Virtual macOS on M1 series Macs

Q

Which versions of macOS can I run in a virtual machine (VM) on my M1 Mac?

AM1 Macs have a different processor from Intel models, and have changed how virtualisa­tion is performed. Intel Macs continue to offer the full range of versions of macOS in several systems, including VMware, Parallels and VirtualBox.

There are fewer options for the ARM processors in M1 Macs, and they require Monterey to work, as support for virtualisa­tion in Big Sur is lacking. Parallels worked with Apple to bring macOS virtualisa­tion early, and

Parallels Desktop 17 now supports running Monterey in a VM on M1 Macs also running Monterey. Unfortunat­ely, it’s not possible to virtualise Big Sur because of deep-seated internal engineerin­g issues.

In the meantime, VMware has been catching up, although it hasn’t made running macOS in a VM a priority, and it’s not clear when it will support that. There’s been no word on whether Oracle’s VirtualBox will even be ported to run on Apple silicon Macs. There’s also the promise that an emulator like UTM might eventually be able to run older Intel versions of macOS one day.

For the moment, the only version of macOS which you can run in a VM hosted on an Apple silicon Mac is Monterey, and for that you’ll need Parallels Desktop running on Monterey.
