The hypervisor is QEMU 4.2.0 on Debian Bullseye. Physical CPU is Intel Kaby Lake.
We need you to create a QEMU/KVM setup for a Mac OS guest.
THE IMPORTANT THING: The Mac OS guest may not know it is running inside a VM! We need the "Content Cache" option of Mac OS working, which is disabled if Mac OS detects running inside a VM!
Show screenshot of "sudo AssetCacheManagerUtil activate" sucessfully activating the content cache as proof that your QEMU/KVM based setup works.
We pay for the documentation how to setup a fully working environment.
If you have an alternative solution for this problem, let us know.
