You can also run Mac operating systems back to High Sierra, 10.13. It is also interesting that Parallels will now run macOS Monterey as a virtual machine, meaning you can run two Macs on one machine, which might be of use, particularly for application testing, or if you need to run Monterey for testing before migrating to the OS on your main Mac. Microsoft has made no announcement concerning its plans, if any, to sell the ARM version of Windows to Mac users for use with Parallels, though the Windows 11 Insider Preview works fine on Apple’s computers, including M1-powered models. The biggest obstacle to Mac users hoping to use Parallels to support Windows 11 on their systems is that Microsoft hasn’t yet officially released the ARM version of Windows for sale.
You’ll also find Intel Macs will support a wider range of guest OSes, mainly because ARM support is only available via Windows 10, 11, Monterey, and Linux distros Ubuntu, Fedora, Debian GNU, and Kali.
One important limitation is that Parallels will work with macOS versions up to High Sierra on Intel Macs, but M1 Macs must run Big Sur or later.
