What they really need is something powerful and open along the lines of QEMU/KVM. HyperKit is dead-last when it comes the virtualization race, and it's one of the technologies I'm rooting for Apple to scrap altogether. MacOS needs either a thinner hypervisor or a lower-level virtualization solution, either of which I see as equally unlikely from Apple.
They added a framework specifically for Linux in Big Sur. Also QEMU runs on MacOS lol
Does MacOS run on QEMU?
It does! Even PPC versions.
Is there an official source of disk images to install macOS in a VM?
QEMU runs on macos already?
That's news to me!
The newest ones with M1/M1 Pro are actually pretty beefy, and even the Macbook Air has benchmarks that beat literally everything else in the Apple lineup except the iMac Pros and the new-model Mac Pros.
This doesn't help much with current equipment, but it should make future planning easier.
