UPDATE: I actually managed to assign a serial number to the VM. Suggestions gladly in the comments! I think, if I would install BigSur natively on my Computer, assigning a serial number would be easier. I didn’t manage to do that with Clover or with a modification of the. Unfortunately, you can only use FaceTime if you assign a (invalid) serial number to the VM. However, if you only need one device, for example to verify an Apple ID, something like this is ideal. I even installed VMWare tools to speed up the VM, even that improved performance only slightly. The programs start a bit slow and the whole behavior of the VM is not optimal. I have tested a few basic programs and have to say that the Vm runs quite laggy, despite the fact that I have allocated 16GB Ram to it.

Anyway, the VM a little slow, even though I installed on a m.2 SSD, provided it 16GBs RAM and installed VMWare tools. I am running the VM on my RIG, that is equipped with a i7 9700K and 48GBs of Ram, so it could run fast enough.
