Parallels Desktop for Mac is software providing hardware virtualization for Macintosh computers with Intel processors, and since version 16.5 also for Apple silicon-based Macintosh computers. It is developed by Parallels, since 2018 a subsidiary of Corel.


Parallels, Inc. is a developer of desktop and server virtualization software.


Released on June 15, 2006, it was the first software product to bring mainstream virtualization to Macintosh computers utilizing the Apple–Intel architecture (earlier software products ran PC software in an emulated environment).

Its name initially was 'Parallels Workstation for Mac OS X', which was consistent with the adobe 3d models corresponding Linux and Windows products. This name was not well received within the Mac community, where some felt that the name, particularly the term “workstation,” evoked the aesthetics of a Windows product. Parallels agreed: “Since we've got a great Mac product, we should make it look and sound like a Mac product.”, it was therefore renamed ‘Parallels Desktop for Mac’.[2]

On January 10, 2007, Parallels Desktop 3.0 for Mac was awarded “Best in Show” at MacWorld 2007.[3]


Parallels Desktop for Mac is a hardware emulation virtualization software, using hypervisor technology that works by mapping the host computer's hardware resources directly to the virtual machine's resources. Each virtual machine thus operates identically to a standalone computer, with virtually all the resources of a physical computer.[4] Because all guest virtual machines use the same hardware drivers irrespective of the actual hardware on the host computer, virtual machine instances are highly portable between computers. For example, a running virtual machine can be stopped, copied to another physical computer, and restarted.

Parallels Desktop for Mac is able to virtualize a full set of standard PC hardware, including[5]

  • A virtualized CPU of the same type as the host's physical processor,
  • ACPI compliance system,
  • A generic motherboard compatible with the Intel i965 chipset,
  • Up to 64 GB of RAM for guest virtual machines,
  • Up to 2 GB of video Parallel desktop (VRAM),
  • VGA and SVGAvideo adapter with VESA 3.0 support and OpenGL and DirectX 10.1 acceleration,
  • A 1.44 MB floppy drive, which can be mapped to a physical drive or to an image file,
  • Up to four IDE devices. This includes virtual hard drives ranging in size from 20 MB to 2 TB each and CD/DVD-ROM drives. Virtual CD/DVD-ROM drives can be mapped to either physical drives or ISO image files.
  • DVD/CD-ROM “pass-through” access,
  • Up to four serial ports that can be mapped to a pipe or to an output file,
  • Up to three bi-directional parallel ports, each of which can be mapped to a real port, to a real printer, or to an output file,
  • An Ethernet virtual network card compatible with Realtek RTL8029(AS), capable of up to 16 network interface connections,
  • Up to eight USB 2.0 devices and two USB 1.1 devices,
  • An AC'97-compatible sound card.
  • A 104-key Windows enhanced keyboard and a PS/2 wheel mouse.

Version history[edit]

Version 2.5[edit]

The first official release of version 2.5 was on February 27, 2007, as build 3186.

Version 2.5 brought support for USB 2.0 devices, which expanded the number of USB devices supported at native speed, including support for built-in iSight USB webcams. The amount of video RAM allocated to the guest OS was made adjustable, up to 32MB. Full featured CD/DVD drives arrived in this version, which allowed the user to burn disks directly in the virtual environment, and play any copy-protected CD or DVD as one would in Mac OS X. In addition, a shared clipboard and drag-drop support between Mac OS X and the guest OS was implemented. This version brought the ability for users with a Windows XP installation to upgrade to Windows Vista from within the VM environment.[6] A new feature known as Coherence was added, which removed the Windows chrome, desktop, and the virtualization frames to create a more seamless desktop environment between Windows and Mac OS X applications. This version also allowed users to boot their existing Boot Camp Windows XP partitions, which eliminated the need to have multiple Windows installations on their Mac. A tool called Parallels Transporter was included to allow users to migrate their Windows PC, or existing VMware or Virtual PC VMs to Parallels Desktop for Mac.

Netsys lawsuit[edit]

This section needs to be updated. Please help update this article to reflect recent events or newly available information.(November 2015)

In 2007, the German company Netsys GmbH sued Parallels' German distributor Avanquest for copyright violation, claiming that Parallels Desktop and Parallels Workstation are directly based on a line of products called “twoOStwo” that Parallels developed on paid commission for Netsys, of which it says, Netsys has been assigned all copyrights. Additionally, the lawsuit claimed that Parallels Desktop 2.5's compatibility with “twoOStwo” showed that the two software products are run by essentially the same functional core.[7] When Netsys lost its initial urgency proceeding, it filed a new suit, in which it requested a temporary injunction from the Landgericht district court of Berlin.[8]

Version 3.0[edit]

On June 7, 2007 build 4124 was released as the first publicly available version of Desktop 3.0.

Version 3.0 retained all of the functionality from previous versions and added new features and tools. Support for DirectX 8.1 and OpenGL[9] was added, allowing Mac users to play some Windows games without the need to boot into Windows with Boot Camp.[10] A new feature called SmartSelect offers cross OS file and application integration by allowing the user to open Windows files with Mac OS X programs and vice versa. Parallels Explorer was introduced, which allows the user to browse their Windows system files in Mac OS X without actually launching Windows. A new parallel desktop feature was included, allowing one to restore their virtual machine environment to a previous state in case of issues. Further, Parallels added a security manager to limit the amount of interaction between the Windows and Mac OS X installations. This version included a long-awaited complete “Parallels tools'” driver suite for Linux guest operating systems. Therefore, integration between Mac OS X and Linux guest-OS's was greatly improved.[11]

Despite the addition of numerous new features, tools and added functionality, the first iteration of Parallels Desktop for Mac 3.0 was missing some of the features that Parallels had planned for it. A Parallels, Inc. representative stated at MacWorld in January 2007 that version 3.0 would bring accelerated graphics, “multi-core virtual machines/virtual SMP, some SCSI support, a more Mac-like feel, as well as a more sophisticated coherence mode, dubbed Coherence 2.0”.[12] While accelerated graphics have materialised, Coherence, as well as the overall look and feel of Parallels Desktop for Mac has only changed slightly. Also, SCSI support has not been implemented.[13]

It is currently unknown if these features have been abandoned altogether, or if they will show up in a later build of version 3.0.

Build 4560, released on July 17, 2007,[14] added an imaging tool which allowed users to add capacity to their virtual disks.

Feature update[edit]

Parallels Coherence in Exposé

Build 5160, released on September 11, 2007,[15] added some new features and updated some current features.

The release focused on updates to Coherence, with support for Exposé, window shadows, transparent windows, and the ability to overlap several Windows and Mac windows. Further, Parallels' Image Tool was updated to allow one to change their virtual hard disk format between plain and expanding. Parallels Explorer was updated to allow for one to automatically mount an offline VM hard drive to the Mac desktop. Some new features added are iPhone support in Windows, allowing iTunes in Windows to sync with it.[16] Users can now mirror desktops or other folders. Further, Mac drives can now be mapped by Windows and sound devices can now be changed ‘on the fly’. Up to 2 GB of RAM can be allocated to a virtual machine, with a total of 4 GB of RAM available.[17]

Parallels Desktop for Mac Build 5608 added support for guest Parallels Tools for Linux in the latest Linux distributions (including Ubuntu 8). It also added support for running 3D graphics in Windows virtual machines on Mac OS X Leopard 10.5.3.

Use of code from the Wine project[edit]

According to Parallels' Licensing page, Desktop for Mac version 3.0 contains Direct3D code that was originally developed by the Wineopen-source project.[18] Wine software is licensed under the GNU Lesser General Public License, Alien Skin Exposure X6 Bundle Crack+ Keygen Key 2021 - Free Activators required Parallels to release the source code. Parallels released the modified source code on July 2, 2007, about 2 weeks after the promised release date.[19] A Parallels spokesman explained the reasons for the delay in a message on the official company blog.[20]

Version 4.0[edit]

Version 4.0, released November 11, 2008,[21] updates its GUI, adds some new features, enhances its performance by up to 50%[22] and consumes 15–30% less power than previous versions.[23] Version 4.0 is the first version that supports both 32-bit and 64-bit guest operating systems. Parallels Desktop 4.0 for Mac's 3D support includes DirectX 9.0, DirectX Pixel Shader 2.0 and OpenGL 2.0[24] as well as 256 MB video memory. It also adds support for 8 GB RAM in a virtual machine and 8-way SMP. Parallels Desktop 4.0 introduces an adaptive hypervisor, which allows users to focus the host computer's resources towards either host or the guest operating system.[25]

Parallels Desktop 4.0 for Mac adds some new features such as:

  • A fourth viewing mode called Modality,[21] which allows users to scale the size of an active guest operating system on the Mac's desktop
  • A new screenshot utility called Clips, which lets users take and share screenshots between the host and the guest operating systems.
  • Start Menu integration and Automatic Windows Notifications on the Apple Menu Bar.
  • The ability to use select voice commands[26] to remotely control the virtual machine.
  • The ability to start and stop a virtual machine via the iPhone. (Requires installing an iPhone application from Apple's AppStore.)

Starting with the Version 4.0 release, Parallels Desktop for Mac has a new logo, which resembles an aluminum iMac, with what appears to be Windows XP on the screen and 2 parallel red lines overlaid on the right side.

Feature update[edit]

Build 3810, released January 9, 2009,[27] includes performance enhancements and features, such as DirectX 9.0 Shaders Model 2 and Vertex Shader support for additional 3D support Intel Streaming SIMD Extensions (SSE4) for better media applications performance. Build 3810 also adds support for running Windows 7 in a VM and for running Mac OS X Snow Leopard Server as either a host or as a guest OS.[28]

Also included are usability features such as the ability to share Windows files by dragging them directly to a Mac application in the Mac Dock. Windows can now also automatically start in the background when a user opens a Windows application on the Mac desktop. Version 4.0 drew criticism for problems upgrading from Version 3.0 shortly after its initial release.[29] Build 3810 also addresses installation and upgrade issues previously experienced with Version 4.0 and introduces the option to enroll in the company's new Customer Experience Program, which lets customers provide information about their preferences and user priorities.

Parallels-desktop meaning

(Parallels Desktop for Mac) Virtual machine software from Parallels, Inc., Renton, WA ( that allows Windows, Linux and other operating systems to run in an Intel-based Mac running Mac OS X. In 2006, Macintosh computers began shipping with Intel x86 CPU chips, enabling K7 total security lifetime activation key to run natively in the machine. Parallels also supports OpenGL 3D, the graphics language used in many high-end games. See virtual machine.Windows on the Mac DesktopIn the Mac, Windows can run full screen or in a window on the desktop. However, Parallels' "Coherence" is the smoothest mode of operation. Windows applications run in individual windows intermixed on the desktop with Mac applications. When minimized, Windows apps appear in the Mac Dock along with the Mac apps. The Windows Start menu can be set to autohide, leaving no trace of the Windows OS on the Mac desktop.Import a Windows Machine - Switch to MacParallels Desktop comes with a migration utility that can move the entire contents of a Windows PC to a Parallels virtual machine in the Mac. It can also convert virtual machines from VMware and Microsoft to a Parallels virtual machine.The Switch to Mac Edition of Parallels includes a USB transfer cable that connects the Windows and Mac machines together for the migration. See Boot Camp, Virtual PC, VMware Fusion and Parallels Workstation.


Parallels Desktop offers a simple way for you to access Windows on your Mac computer. If you own a Mac, you are probably aware that you cannot access Microsoft Windows applications on your device. But while this is the standard, it doesn’t have to be the case. Reliable virtualization software can get you access to any OS and program that you want on your Mac. Let’s explore the world of virtualization and its application through Parallels Desktop.


Parallels Desktop


What Is Parallels Desktop?

Parallels Desktop is software that lets you create virtual machines within your Mac. A virtual machine is essentially a digital replica of a computer located inside another computer. Each virtual machine runs on its own operating system (OS) and applications. You can choose which OS or applications you want to install. Once you’ve already installed an OS within a virtual environment, you can already use it as a typical computer. That is, you can run applications, create and manage files, access the internet, and so on.

If you are on the lookout for virtualization software, here is a list of the best virtual machine software available.


How Much Is Parallels Desktop? Plans & Pricing


All versions of Parallels are available for download from the official Parallels website. There are three tiers available: Standard, Pro, and Business versions.

They offer discounted prices for students and a 14-day free trial period for anyone who would like to try out the software. In addition, customers who purchase the recently released Parallels 16 or 16.5 may be entitled to a free upgrade. However, there are a few conditions regarding the date of purchase and the location of purchase. Check their official website for details.


Standard Edition

The standard edition of Parallels 17 is a great tool for students and beginners. It can be yours for a one-time fee starting at $79.99. Optimized for macOS Monterey, the Standard version features seamless Mac integration and disk space optimization as you run the Windows OS on your Mac ecosystem.


Mac Pro Edition

The MacPro edition is the high-end version of Parallels 17. All of the features that you can find in the Standard edition are included here. You also have the ability to create an entirely new virtual machine from a clone virtual machine. It also features a Visual Studio plugin that is designed for debugging code in a standalone VM. The plugin installation process for Visual Studio2910 has also been simplified.


Mac Business Edition

The Mac Business edition was not made for enterprise-level for nothing. This version offers micromanaging capabilities for your virtual machines. For starters, it allows managers to assign any number of Windows virtual machines to Mac computers. These Mac computers can run on either Intel or Apple M1 chips. It also makes it possible to mass deploy applications to Mac computers running on both Intel and M1 chips.


How to Get Parallels Desktop? Things You Need

System Requirements

System Requirements

Virtual machines are no simple thing to deal with, hardware-wise. They take up many system resources from the host device, which the host device might also need. As such, it’s imperative that your computer match the system requirements of the software. In addition, it must have the system resources to spare for a virtual machine.


Host OS Compatibility

First off, your computer should be MacOS 10.13 or later. If you’re not sure about your device’s OS number, you can check for its name. The operating systems that qualify for this include High Sierra, Mojave, Catalina, and Big Sur. Take note that versions 16 and 16.5 of the software are only compatible up with MacOS 11. Only Parallels 17 is compatible with the upcoming macOS Monterey.


Memory and Storage

The other two crucial requirements have to do with memory and storage. When it comes to memory, you will need to have at least 4 GB to spare. You will also need a lot of extra storage to accommodate both your software and the guest operating system.

The installation process for Parallels alone will set you back around 500 MB of storage. Of course, you’ll also need to find space for your guest operating system to “live” in. After all, they are literal “guests” on your computer. As per Parallels estimates, you’ll need at least 16 GB of storage space for it.

However, the storage requirement of operating systems also differ. For example, Linux Ubuntu and Windows 10 only take up around 15 GB of storage. On the other hand, you have the upcoming Windows 11, requiring at least 27 GB of storage. While the discrepancies aren’t large, they certainly are there. Thus, it may be a good idea to check storage requirements for your chosen OS beforehand.



Another requirement relates to the chip processor. Parallels Desktop accepts a handful of brands that it deems as top-performers. That includes the Apple M1 chip, a variety of Intel Core chips, and Xeon processors.


Compatible Guest OS

Windows OS

Parallels 17 supports a wide selection of operating systems. But in general, the list can be split into two categories based on the processor being used.


Mac with Apple M1 Chip

Macs with the Apple M1 chip can install a selection of operating systems. That includes various versions of Ubuntu Linux, Fedora Workstation, Debian GNU/Linux, Kali Linux, and macOS Monterey.


Mac with Intel Processors

Macs with Intel processors should be able to support even more types of OS. But of course, the priority is always with Windows systems. The list includes Windows 7 to 11 and Windows Server (2012-2022 versions). It also offers to virtualize the different versions of  Windows Vista, Windows XP, and Windows 2000.

In addition, it supports a variety of other non-Windows operating systems, including Linux, Kali, ElementaryOS, and Solaris. It also supports more obscure types like OpenBSD, ReactOS, Android, and OS X.



Software Installation

The installation process for Parallels Desktop is simple and fast. It is not different from any other Windows-based software. Like any other download, it starts through the official website, where you have to download the DMG copy of the software. This file takes up about 200 GB of storage.

After downloading the file, the software will present you with a software agreement for approval. It will then ask for your Parallels credential to proceed with the installation.

Once you’ve installed the software, the system will present you with quite a long list of permissions. First, it will ask for access to your Downloads folder (on Mac), permission to issue notifications for Parallels Desktop via alerts, sounds, and icon badges, and access to your desktop, documents, and downloads. You can choose which of these you want to provide access to.

At some point, Parallels will offer to download Windows 10 for you. If you agree, it will create a new Windows virtual machine. If you have a virtual machine already prepared, you can skip to the section that allows you to upload it. After a few more hardware permission, you will be asked to sign in to Parallels to confirm your subscription and payment method. This is a requirement before you can access your virtual machine.


Parallels Desktop Review

Top Features

Parallels Features

Parallels have been on a roll this year, and that has a lot to do with the need to keep up with new Microsoft and Apple releases. That is, both brands are set to release a new OS this year. Microsoft has Windows 11 in tow, while Apple has the MacOS Monterey. Not to mention, Apple is also making the switch for their CPU/GPU to the brand-new Apple M1 chip.

These developments combined prompted Parallels to release three versions of their software within the span of one year. Normally they would only release a single version to match the annual release of a new macOS. This time, they released Parallels 16, Parallels 16.5, and Parallels 17 within a span of one year.

For this review, we’ll be focusing on the features of the latest edition.


Compatible with macOS Monterey and Windows 11

Windows 11

Parallels has been preparing to deal with whatever it is Mac and Windows throws in its way. As such, they’ve made the latest version compatible with macOS Monterey as both host and guest operating system (OS). They have also optimized the software to accommodate Windows 11.

This means that you can install them through a virtual machine when either of these OS comes out. It also means that any device carrying the new macOS Monterey can host Parallels.


Sidecar and Apple Pencil Support

Apple Sidecar

Parallels has also crossed over a few functions that are normally found on Macs but not on Windows. The best example of this would be its latest support for Sidecar. Sidecar is an app that allows you how to make flipping book turn your tablet into a secondary display for your Mac screen. In other words, you can reflect your screen on two devices at the same time. When applied to Parallels, it allows you to view specific Windows app via your Mac tablet. You can also use your Apple Pencil to navigate the screen on the tablet.


Speed Improvements

Speed Improvements

Speed is another area where Parallels 17 excels. The speed improvements are just across the board. As a matter of fact, Parallels provides some statistics regarding the speed of their latest version. The results indicate that the latest version of Parallels can run Windows nearly forty percent faster than before.

Parallels 17 has also improved graphics performance by as much as twenty-five percent and twenty-eight percent for DirectX. Disk performance has also improved by 20% for Apple M1 users versus Parallels Desktop 16.5. As all of this data implies, speed improvements are maximized when the host Mac uses an M1 chip.


Improved Gaming Graphics

Gaming Graphics

The Parallels Desktop 17 also benefits from an improved display driver, for the gamers’ sake. A display driver is a bridge between a computer system’s operating system and its graphics hardware. In simpler terms, it’s the hardware component that controls the monitor. The new driver increases the frame rate of the graphics for virtual games. This allows for seamless virtual streaming and gaming.

Similar technology to virtualization software exists, Bandicam Crack it’s in the field of gaming. It’s called a gaming emulator, and it simulates the hardware of gaming consoles on your computer.

If you’d like to explore the topic, check out our list of the best PS2 emulators and PS3 emulators. 


Battery Optimization

Battery Optimization

The latest version of the software allows the guest OS to recognize when the host OS is running low on power. In which case, it will enable a battery-saving mode for the guest OS to prevent it from draining the host device. The latest version also features a new virtual TPM chip that can encrypt your entire drive for extra data protection.

It also features support for multiple sound channels and the ability to detect connections with native drivers. In addition, it also features better resolution for Linux virtual machines in windowed view mode. This should allow your VM’s resolution to stay the same despite window resizing.


Coherence Mode 

Coherence Mode

Coherence is one of the older features of Parallels. This mode allows users to view Mac and Windows OS side by side. The only exception is that the Windows desktop does not appear. Only the Windows app that you are currently using will appear on the desktop. Any shutdowns or interruptions, even notifications on either OS, will not be reflected.

This type of setup is great for people who need to work with both systems simultaneously. It allows for a distraction-free steady dual interface. Besides Coherence, Parallels also offers other modes, including windows, full-screen, and picture-in-picture modes.


Automatic Resource Manager

Resource Manager

Parallels also added a new feature called the automatic resource manager. As you can probably guess from the name, this feature tries to assess the optimal allocation of resources for your virtual machines. It operates much like the app manager on Android and the resource manager on Windows desktop.


Easy Transfer of Files

File Transfer

The process of transferring files from your Mac to your Windows virtual machine is also made easier in Parallels 17. Now, it’s possible to copy and paste or drag and drop photos and other files from your guest OS to your Mac. This feature is very similar and was likely inspired by the new macOS Monterey feature. This particular feature also allows you to drag and drop content from Windows to Apple via the QuickNote feature.


Swipe Gesture

Parallels Swipe Feature

This is a new feature that many will find very convenient. It offers a simple way to access system controls, not to mention switching between operating systems.

For example, a simple three-finger swipe towards the top-right corner of your device will give you access to your desktop. A three-finger tap on the screen will give you access to a “Lookup” feature. It’s also possible to switch between applications or operating systems via a single, three, or two-finger swipe.


Microsoft Office 365 Integration

MS Office

Another defining feature of Parallels 17 is its ability to interact with Microsoft Office apps. This allows you to access the basic lineup of Microsoft Office apps, including Excel, Word, and PowerPoint. In other words, you can work on a document or review a document on your virtual machine running Windows OS. In addition, the Microsoft applications can open up normally on any native Mac web browser.


Multiple Connectivity Options

Cable Connectivity

Parallels 17 also allows you to connect your devices to a wide range of external devices. Of course, the connection has to be made physically via USB, USB-C, FireWire, and Thunderbolt. The software is also able to pair with a variety of Bluetooth devices. This may include things such as your Xbox One, Logitech Craft keyboard, or stylus pen, or printer. It also offers support for the internet of things (IoT) devices like smart speakers, smart lights, and so on.


Ease of Use

Ease of Use

Parallels Desktop has a very user-friendly interface. The system automatically detects whether you already have Windows on your system or if you still need to get it. The setup process is very organized and easy to understand. Navigating the software itself is very easy since all of your options are clearly laid out. Not to mention, you also have a single-swipe function that switches systems quickly. Overall, this is a very clean and organized system with a manageable learning curve.


Customer Support

Customer Support

Parallels also offers full-time customer support, but it’s partial towards premium subscribers. Those who get the MacPro or Mac Business editions get full customer support as long as they’re subscribed. They can contact customer support via chat, email, or telephone. Those who opt for the Standard package still get customer support, but access will be time-limited. Chat and email support expire after 30 days from the date of purchase. Meanwhile, email support expires after two years.


What Are Virtual Machines?

Virtual Machines


Virtualization software may mimic the form of an OS, but it’s an entirely different species of software. In order to fully understand how it works, we need to understand the basic concepts associated with it. We also need to explore the differences between a virtual machine and your standard OS. Here are some of the ways that virtualization software differs from Windows, Mac, or Linux.


Guest vs Host Operating Systems

When discussing virtual machines, we need to make the distinction between a guest and host operating system. A guest operating system is the one that sits inside the virtual machine. It’s the OS that is being simulated since it is not natively available on the device. On the other hand, the computer’s operating system that you are using to run the virtual machine is called the host operating system.


No Hardware

The defining factor of guest virtual machines is that they don’t have their own hardware to support them. Instead, it asks to share system resources with the guest operating system. It borrows portions of your hardware resources such as CPU, RAM, storage, GPU, and NIC. In the case of Parallels, the software only works with devices that run on macOS.



A virtual machine cannot manually interact with the hardware of your computer. Instead, it relies on a management software called the hypervisor. The hypervisor coordinates between the virtual machines and the physical hardware. It negotiates between the two parallel desktop allocate system resources from the hardware to the virtual machine.


System Requirements

Theoretically, you can install and run as many virtual machines as you want with each. But in reality, the amount of RAM, hard drive storage help to determine how many virtual machines you can accommodate in a single device. There’s also compatibility, meaning that your device has to match the computer model, processor chip, and graphics card requirements.



Perhaps the most notable aspect of virtual machines is that they are completely insulated. This means that anything Unreal Commander Download - Crack Key For U do within a virtual machine will not affect other virtual machines. Its effects are also insulated from the larger host operating system.


What Are the Benefits of Virtualization?

Benefits of Virtualization

Virtual machines offer a variety of benefits that you cannot find in traditional computers. Here are some of those benefits:


Multiple OS

For starters, the most obvious benefit is it allows you to run multiple operating systems at once. For the longest time, we have been accustomed to selecting a single operating system for our devices, but now it’s possible to have multiple operating systems running on a single computer.

Because of virtualization, it’s not possible to run foreign software such as Windows on Linux or Mac without a reboot. You also get to pick the operating system you want to install, and you can opt for legacy versions of Windows or Linux.


Resource Efficiency

Virtual machines also reduce hardware and electricity costs, which is an advantage for business owners. They don’t require their own hardware to function, parallel desktop makes them cost-efficient. Virtual machines are also much easier and faster to set up than traditional servers. Installing servers requires a long, multi-step process that takes days to complete. Meanwhile, installing virtual machines is very simple and only takes a few minutes. With virtual machines, you can deploy a new server within minutes.

Virtual machines are also far more efficient than traditional servers. Once installed, you can easily freeze, wake up, back up, and transport virtual machines between hosts. In addition, virtualization also increases operational efficiency. That is, it’s easier to manage multiple operating systems on a single server.



Virtual machines are also able to function in an insulated manner. It allows software developers to experiment within a safe environment. That is, if a virtual machine gets compromised, its effects will not spill over to other VMs. With an environment such as this, you can create as many experimental projects as you want, and any mistakes will not affect the host operating system. In addition, most virtual machines have a snapshot ability. This allows the user to freeze a particular state of the virtual machine and revert to it later.


Final Thoughts on Parallels Desktop

Parallels Official

Overall, Parallels Desktop is a great software for creating virtual machines. It’s one of those rare gems that present a novel solution to a long-held problem. In this case, the problem was how to combine multiple operating systems using a single hardware setup.

As it turns out, virtual machines have been around for a long time.  It’s just that it has never been applied at the level of mass-produced electronics. Parallels is one of the few software to bridge that gap, and it’s a nearly perfect embodiment of what virtualization technology should look like.

While we would have liked to see Parallels offer a version for Windows, it’s a small disadvantage. Because of software like Parallels, we don’t have to pick between Windows and Mac since we can have both and so much more.



Today, we're excited to announce the release of SynapseML (previously MMLSpark), an open-source library that simplifies the creation of massively scalable machine learning parallel desktop pipelines. Building production-ready distributed ML pipelines can be difficult, even for the most seasoned developer. Composing tools from different ecosystems often requires considerable "glue" code, and many frameworks aren't designed with thousand-machine elastic clusters in mind. SynapseML resolves this challenge by unifying several existing ML frameworks and new Microsoft algorithms in a single, scalable API that's usable across Python, R, Scala, and Java.

With SynapseML, developers can build scalable and intelligent systems for solving challenges in domains such as: windows 7 key product

• Anomaly detection
• Computer vision
• Deep mediamonkey windows media player - Free Activators • Form and face recognition
ZIP Password Recover Crack & Activation Key [Latest] 2021 • Gradient boosting
• Microservice orchestration

• Model interpretability
• Reinforcement learning and personalization
• Search and retrieval
• Speech processing
• Text analytics
• Translation

Simplifying distributed ML through a unified API

Writing fault-tolerant distributed programs is complex and a process that's prone to errors. For example, consider the distributed evaluation of a deep network. The first step is to send a multi-GB model to hundreds of worker machines without overwhelming the network. Then, data readers must coordinate to ensure that all data is queued for processing and that GPUs are at full capacity. If new computers join or leave the cluster, new worker machines must receive copies of the model, and data readers need to adapt to share work with the new machines and re-compute lost work. Finally, progress must be tracked to ensure resources are properly freed.

Sure, frameworks like Horovod can manage this, but if a teammate wants to compare against a different ML framework, such as LightGBM, XGBoost, or SparkML, it requires a new environment and cluster. Moreover, these training systems aren't designed to serve or deploy models, so separate inference and streaming architectures are required.

SynapseML simplifies this experience by unifying many different ML learning frameworks with a single API that is scalable, data- and language-agnostic, and that works for batch, streaming, and serving applications. It's designed to help developers focus on the high-level structure of their data and tasks, not the implementation details and idiosyncrasies of different ML ecosystems and databases.

A unified API standardizes many of today's tools, frameworks, and algorithms, streamlining the distributed ML experience. This enables developers to quickly compose disparate ML frameworks for use cases that require more than one framework, such as web-supervised learning, search engine creation, and many others. It can also train and evaluate models on single-node, multi-node, and elastically resizable clusters of computers, so developers can scale up their work without wasting resources.

In addition to its availability in several different programming languages, the API abstracts over a wide variety of databases, file systems, and cloud data stores to simplify experiments no matter where data is located, as shown in Figure 1.

General availability, parallel desktop enterprise support on Azure Synapse Analytics

Over the past five years, we have worked to improve and stabilize the SynapseML library for production workloads. Developers who use Azure Synapse Analytics will be pleased to learn that SynapseML is now generally available on this service with enterprise support. They can now build large-scale ML pipelines using Azure Cognitive Services, LightGBM, ONNX, and other selected SynapseML features. It even includes templates to quickly prototype distributed ML systems, such as visual search engines, predictive maintenance pipelines, document translation, and more. Please see this GA announcement guide for added details.

Getting started with state-of-the-art, pre-built intelligent models

Many tools in SynapseML don't require a large labelled training dataset. Instead, SynapseML provides simple APIs for pre-built intelligent services, such as Azure Cognitive Services, to quickly solve large-scale AI challenges related to both business and research. SynapseML enables developers to embed over 45 different state-of-the-art ML services directly into their systems and databases. The latest release includes added support for distributed form recognition, conversation transcription, and translation, as illustrated in Figure 2. These ready-to-use algorithms can parse a wide variety of documents, transcribe multi-speaker conversations in real time, and translate text to over 100 different languages.

Working with web services at scale can be challenging due to networking issues, throttling, and large amounts of CPU downtime while the client waits on the server's response. To make SynapseML's integration with Azure Cognitive Services fast and efficient, we introduced several new tools into Apache Spark. In particular, SynapseML automatically parses common throttling responses to ensure that jobs don't overwhelm backend services. Additionally, it uses exponential back-offs to handle unreliable network connections and failed responses. Finally, Spark's worker machines stay busy with new asynchronous parallelism primitive to Spark. This allows worker machines to send requests while waiting on a response from the server, which can yield a tenfold increase in throughput. Table 1 shows how these features help SynapseML achieve significantly better throughputs than many baseline implementations. The paper Large-Scale Intelligent Microservices provides a deeper look at this system's architecture.

Broad ecosystem compatibility with ONNX

For tasks that cannot be solved with existing cognitive services, SynapseML enables developers to use models from many different ML ecosystems through the Open Neural Network Exchange (ONNX) framework and runtime. With this integration, developers can execute a wide variety of classical and deep learning models at scale with only a few lines of code. This integration between ONNX and Spark automatically handles distributing ONNX models to worker nodes, batching and buffering input data for high throughput, and scheduling work on hardware accelerators, as shown in Figure 3.

Bringing ONNX to Spark not only helps developers scale deep learning models, it also enables distributed inference across a wide variety of ML ecosystems. In particular, ONNXMLTools converts models from TensorFlow, scikit-learn, Core ML, LightGBM, XGBoost, H2O, and PyTorch to ONNX for accelerated and distributed inference using SynapseML. Furthermore, we have contributed the ONNX Model Hub, making it easy to deploy over 120 state-of-the-art pre-trained models across domains, such as vision, object detection, face analysis, speech recognition, style transfer, and others.

Training your own reinforcement learners with Vowpal Wabbit

SynapseML enables developers not only to use existing models and services, but also to build and train their own. This release of SynapseML introduces new algorithms for personalized recommendation and contextual bandit reinforcement learning using the Vowpal Wabbit framework. This Vowpal Wabbit integration can distribute model training and prediction for a single model or parallelize training across multiple models. This is especially useful for quickly tuning hyper parameters of policy optimization and personalization systems. New users can get started with Vowpal Wabbit on this GitHub page.

Building responsible AI systems with SynapseML

After building a model, it's imperative that researchers and engineers understand its limitations and behavior before deployment. SynapseML helps developers and researchers build responsible AI systems by introducing new tools that reveal why models make certain predictions and how to improve the training dataset to eliminate biases. More specifically, SynapseML includes distributed implementations of Shapley Additive Explanations (SHAP) and Locally Interpretable Model-Agnostic Explanations (LIME) to explain the predictions of vision, text, and tabular models. For example, Figure 4 shows how to quickly interpret a trained visual classifier to understand why it made its predictions. Ordinarily, these opaque-box methods typically require thousands of model evaluations per explanation, and it can take days to explain every prediction over a large a dataset. SynapseML dramatically speeds the process of understanding a user's trained model by enabling developers to distribute computation across hundreds of machines.

In addition to supervised model explainability, SynapseML also introduces several new capabilities for unsupervised responsible AI. With our new tools for understanding dataset imbalance, researchers can detect whether sensitive dataset features, such as race or gender, are over- or under-represented and take steps to improve model fairness. Furthermore, SynapseML's distributed isolation forest enables researchers to detect outliers and anomalies in their datasets without needing labelled training data. Here at Microsoft, we are actively using these techniques to detect and prevent abuse on LinkedIn.

Finally, Azure Synapse Analytics users can take advantage of the private preview of a distributed implementation of Explainable Boosting Machines, which combines the modeling power of gradient-boosted trees with the interpretability of linear additive models. This allows data scientists to learn high-quality nonlinear models without sacrificing their ability to understand a model's predictions.

Simplifying the path to production systems

We hope developers and others who build production-ready scalable ML systems find that SynapseML simplifies the process. SynapseML standardizes a variety of ML frameworks, such as those mentioned in this blog post, to enable new classes of ML systems that compose pieces from different ML ecosystems. Our goal is to free developers from the hassle of worrying about the distributed implementation details and enable them to deploy them into a variety of databases, clusters, and languages without needing to change their code. Moreover, with our announcement of the general availability of SynapseML on Azure Synapse Analytics, developers can depend on enterprise support for their production systems.

Parallels Desktop 16.5 Enables Windows 10 on Mac M1 at Native Speeds

Parallels has released a new version of its Parallels Desktop for Mac virtualization software that features full native support for Mac computers equipped with either Apple M1 or Intel processors. The program allows users to run Windows 10 Arm Insider Preview as well as various Linux distributions on systems running the M1 SoC at native speeds. 

Running Windows on Apple's Mac computers may not be a priority for most of their owners, but there are still quite a lot of users who need to run Windows applications from time to time. Since the latest Apple MacBook Air/Pro 13 and MacMini are based on the Arm-powered M1 SoC, it's impossible to install regular Windows 10 as the second OS on them. Furthermore, unlike other programs for Mac, virtualization machines did not run well on M1-based Macs via the Rosetta layer, so Parallels had to redesign its Parallels Desktop to make it run on an Apple's M1 SoC natively. 

Parallels Desktop for Mac 16.5 supports all the capabilities that that users of PDM are used to on Apple M1 systems, including coherence mode, shared profile, and touch bar controls, just to name a few. 

In addition to Windows 10 for Arm, Parallels Desktop for Mac 16.5 also supports guest operating systems on M1 Macs,including Linux distributives Ubuntu 20.04, Kali Linux 2021.1, Debian 10.7, and Fedora Workstation 33-1.2. 

To ensure flawless operation of its Parallels Desktop for Mac virtual machine, Parallel used help of more than 100,000 Mac M1 users who ran Microsoft’s Windows 10 on Arm Insider Preview along with various software from PowerBI to Visual Studio and from SQL server to Meta Trader. In addition, engineers from Parallels did not forget games and ensured that titles like Rocket LeagueAmong UsRobloxThe Elder Scrolls V: Skyrim, and Sam & Max Save the World worked well on Parallels Desktop for Mac 16.5 and Apple M1-powered systems.

Right now, Parallels Desktop for Mac 16.5 is good enough to launch it commercially, according to the company. 

There are some interesting findings about performance of Apple M1 and Parallels Desktop 16.5 for Mac: 

  • An M1-based Mac running Parallels Desktop 16.5 and Windows 10 Arm consumes 2.5 times less energy than a 2020 Intel-based MacBook Air.
  • An Apple M1 machine running Parallels Desktop 16.5 and Windows 10 Arm performs 30% better in Geekbench 5 than a MacBookPro with Intel Core i9-8950HK in the same conditions.
  • Apple M1's integrated GPU appears to be 60% faster than AMD's Radeon Pro 555X discrete graphics processor in DirectX 11 applications when running Windows using the Parallels Desktop 16.5.

"Apple's M1 chip is a significant breakthrough for Mac users," said Nick Dobrovolskiy, Parallels Senior Vice President of Engineering and Support. "The transition has been smooth for most Mac applications, thanks to Rosetta technology. However, virtual machines are an exception and thus Parallels engineers implemented native virtualization support for the Mac with M1 chip. This enables our users to enjoy the best Windows-on-Mac experience available."


How can I stop Parallels Desktop from listing Apps from a VM available in Spotlight?

I'm trying to stop Windows apps installed on a VM in Parallels from appearing in Spotlight search results on the host Mac. System details:

  • Mac OS: 10.12.6
  • Parallels Desktop Business Edition Version: 11.2.3 (32663)
  • Windows OS Version (running in Parallels): Windows 10 Pro 1709

I've made sure that in Parallels setting for this VM, the setting Options ➡️ Applications ➡️ Share Windows applications with Mac is set to false:

Parallels Settings

In addition, as suggested here, I've added to the Spotlight privacy blacklist:

Parallels Apps Blacklisted

Finally, as suggested by @JMY1000, I rebuilt the entire Spotlight index on my Mac, by following these instructions.

And yet still, I can see Windows Apps listed in Spotlight results:

Parallels Desktop 17 is here and ready to run Windows 11 on M1 Macs

with 66 posters participating

Parallels Desktop 17 has arrived with support for macOS Monterey and Windows 11. Further, the popular virtualization software for Macs is now a universal binary, making deployment a little less complicated for many IT professionals.

Note that you can only run ARM versions of Windows (10 or 11) on Macs with Apple Silicon chips like the M1. Both Windows 10 and 11 for ARM are available as Insider Preview builds. On the other hand, Parallels can run versions of Windows going back as far as XP if you're running it on an Intel Mac. A number of Linux distros are also supported, though Intel Macs gain access to more of those than M1 Macs do.

If you have access to those Insider Preview builds, you can run most Windows applications on your M1 Mac, Parallels' developers say, because Windows on ARM can run both 32-bit and, more recently, 64-bit x86 applications. That said, even on machines it's designed to run on, Windows on ARM can be occasionally fussy about x64 apps. So your mileage will likely vary depending on what you're trying to do.


In any case, Parallels is claiming significantly improved performance on M1 Macs compared to last year's release, which was the first to add support for said Macs. In particular, DirectX 11 performance is getting a boost (Parallels says it's 28 percent faster). Also, both Intel and ARM Macs will see up to sixfold-better OpenGL performance with Windows virtual machines.

There are other added features and quality of life improvements, too. For example, you can now drag and drop content between apps running under macOS and those running in Windows while using Parallels in Coherence mode. There are other improvements to Coherence, too, like Windows shutdown and sign-in screens parallel desktop are presented in a way that feels more native and natural within macOS.

Don’t forget Monterey

Also, support for this year's new version of macOS, Monterey, has been added. As is customary with these annual updates, the new version of Parallels Desktop will be able to run on Monterey host machines or run Monterey in virtual machines.

The other big addition is virtual TPM chip support for Windows 10 and 11 virtual machines, facilitating features like BitLocker and Secure Boot.

Parallels Desktop 17 costs $79.99 annually for the standard edition or $99.99 for the "Pro" edition. The Pro edition includes a Visual Studio debugging plugin that now works on M1 Macs, among other bonuses specific to some professional use cases.
