Best Prices Today: Parallels Desktop for Mac

The Mac is no longer dismissed as an insignificant niche market that struggles to compete with Microsoft Windows. But, even so, there are still times when many Mac users need to run apps and software that are only available for Windows PCs. Perhaps your employer uses particular business software that’s only available for Windows, or you may need to use a website that relies on some Windows-only technologies. Many developers need to test their apps and services on both Macs and PCs and, of course, there are all those A-List games that only run on Windows as well.

It used to be easy to install Windows on Macs, thanks to Apple’s Boot Camp software and the fact that from 2026 to 2020 all Macs used the same Intel processors as Windows PCs. However, with the advent of M-series Macs, Boot Camp is no more, so if you want to run Windows on a Mac you need to consider one of the various virtualization options that we feature in our round-up of the Best Virtual Machine software for Mac.

The advent of Apple’s own chips, aka Apple Silicon, also means that the standard version of Windows, designed for X-86 chips, won’t run on Arm-based chips like Apple’s M-series. If you want to run Windows on an M-series Mac you need the Arm version of Windows. 

Our top solution for running Windows on a Mac is Parallels Desktop. Read on to find out why. 

What is Parallels Desktop for Mac 

Parallels Desktop is referred to as a virtualization program, because it allows you to create a virtual machine on your Mac – sometimes known as a VM – which is essentially a piece of software that simulates the physical hardware of a Windows PC (process also known as emulation) and lets you run Windows on your Mac.  

One of the benefits of a solution like Parallels Desktop is it allows you to run Mac and Windows apps side by side, without having to reboot your Mac to switch between the macOS and Windows (which you had to do with Boot Camp).

Parallels gives you a lot of control over how you integrate Windows on your Mac. You could choose to keep Windows and macOS completely separate, with a full Windows desktop window floating on the Mac desktop, or the Windows VM can be expanded to full-screen size to hide the Mac desktop. But you can also use Coherence mode to run your Windows apps on your Mac so that they integrate fully with your Mac apps–you can even add them to your Dock.

You can run more than Windows as a VM on your Mac with Parallels Desktop. You can create a VM that runs Linux, or even a VM that runs a different version of macOS itself. This can be useful for developers who need to test a website or an app on different versions of the macOS, although it’s currently only possible to create VMs that run Monterey (macOS 12.0) or later on Macs with Apple Silicon. However, Intel-based Macs can go right back to Mac OS X 10.7 Lion–we have the details of how to find old version of macOS here.

Another useful feature of Parallels is Rollback mode, which lets you run Windows (or Linux, or macOS) like a kiosk. What this means is that nothing is saved and after you have finished working and restart the computer the VM will return return to it’s original state, this is perfect for developers who can experiment and then return to a clean slate.

Parallels also makes installing Windows really easy. Since Parallels Desktop version 18 it has been possible to download and buy the ARM version of Windows 11 directly within Parallels. You do need to buy a license for the ARM version of Windows 11 Pro or Enterprise in order to create a Windows VM on Macs with Apple Silicon processors – unfortunately, the less expensive Home edition isn’t supported – although it’s also possible to use an existing license if you have one available. Microsoft doesn’t differentiate between Windows On Intel and Windows On Arm, so a Windows 11 license can be used for either version.

This is a big deal because the Arm version of Windows isn’t normally licensed to individual users. Fortunately, Parallels has worked closely with Microsoft to simplify the process of creating VMs that use the ARM version of Windows. Just select the File/New command to create a new VM (or press the ‘+’ button in the program’s main Control Centre window) and it will present you with a big button labeled: Get Windows 11 From Microsoft. 

Windows 11 On ARM allows you to run most older software and apps that were originally written for the Intel version of Windows, so you shouldn’t have any compatibility problems when running virtual machines that use Windows On ARM.

Older Intel-based Macs can still run Windows 10 via Parallels, although older versions of Windows are no longer supported.

Parallels Desktop system requirements 

Since your Mac is effectively running two operating systems at the same time–the macOS and Windows–so you’ll need a reasonably fast Mac with plenty of memory, disk space and – above all – processor power in order to run your virtual machines efficiently. 

Fortunately, modern multi-core processors like Apple’s M-series of chips can run routine apps such as the Windows versions of Microsoft Word or Excel using virtualization with no trouble at all, and faster Mac models can do a pretty good job running 3D games or high-end tools for design and graphics work.

You do need plenty of memory to run the macOS and Windows alongside each other though. Parallels Desktop generally recommends a minimum of 1-2GB for each VM, but that really is the absolute minimum, and it’s in addition to the memory that your Mac needs just to run the macOS, so if you’ve got a Mac with just 8GB of memory then you’re not going to get the best possible performance when running Windows in a VM.

Juggling memory and processor cores can be confusing for less experienced users, but Parallels Desktop can help by recommending settings that will be suitable for running different types of Windows apps and software. On high-end Macs, such as the Mac Studio, you can configure your virtual machines to use up to 62GB of memory and 18 CPU cores for improved performance. Unfortunately, Parallels informed us that the multiple GPU cores on Apple Silicon chips are controlled solely by the macOS itself, so Parallels doesn’t currently allow you to also specify the number of GPU cores used by your virtual machines.

Parallels Desktop update: What’s in Parallels Desktop 20 for Mac?

One other benefit is that Parallels Desktop has a regular update cycle of annual updates that generally coincide with Apple’s big updates to the macOS itself. Parallels also keeps up with the rapid development of Apple’s M-series processors.

Speaking of regular updates, Parallels Desktop 20 arrived in September 2024, bringing support for macOS Sequoia and new features in that version of macOS. 

Parallels 20 includes a number of new features that are only available to Mac’s running Sequoia. With Sequoia as your Mac’s main operating system – rather than just a guest running in a virtual machine – you now have the ability to sign into a Mac virtual machine (VM) using your Apple ID, which will allow you to use your Apple email and other Apple services. And it will be possible to use the Apple Intelligence-powered Writing Tools feature within Windows apps once that arrives on Macs later in 2024.

There are performance improvements when using Parallels’ file-sharing features to exchange files between your main Mac and your virtual machines. Macs with Apple Silicon also gain the ability to quickly save and restore ‘snapshots’ of your VMs so that you can make or discard changes to your VMs for testing purposes (although the snapshots feature was already available when running Parallels on Macs with Intel processors in the past).

Parallels Desktop 20 is also compatible with the latest Windows 11 On Arm update – known as 24H2 – which has an improved Prism emulator that provides as much as 80% performance improvement when running some older Windows apps that were written for Intel processors. Prism is similar to Apple’s Rosetta, which allows old Mac apps that were written for Intel processors to run on modern Mac
