This is maybe what UTM uses in the latest releases to virtualize macOS on ARM64? Works very well for me so far. https://github.com/utmapp/UTM/releases

If you’re looking for a lighter weight vm (microvm almost), check out lima and colima.

Big +1 for lima. It's basically WSL2 for macOS.

It’s not clear to me what colima[0] adds to lima[1]. Does anyone know?

Love me some UTM. I use it to virtualize the ARM version of Kali. Works flawlessly on M1 MacBook Air!

UTM appears to be based on qemu, and it has full emulation capabilities.

edit: in addition to native virtualization, as noted below

Under "Additional macOS features":

- Hardware accelerated virtualization using Hypervisor.framework and QEMU

- Boot macOS guests with Virtualization.framework on macOS 12+

So, it does use Virtualization.framework for macOS guests.

Indeed. Note that qemu has support various native virtualization platforms including kvm, macOS' hypervisor framework, and Windows hypervisor. I'm not sure whether qemu supports M1 macOS out of the box (though it does seem to support ARM Linux and Windows) though, so perhaps that's an added feature from UTM.

Support for using Hypervisor.framework on M1 Macs was added in 6.2:

>On macOS hosts with Apple Silicon CPUs we now support the 'hvf' accelerator for running AArch64 guests

nice

Qemu doesn’t support vmnet (so you cannot have host-only and bridge network modes using Mac hosts)

https://github.com/utmapp/UTM/releases/tag/v2.2.4

(macOS 11.3+ Only) Bridged networking and shared networking support.

Can you use iCloud?

No.

Is there any reason why it's impossible to use iCloud or any Apple sign in? I can't find anything in UTM documentation.
