Actually I think you don't need supperior knowledge to make that up.
I mean, after all Macs are just x86 computers with some TPM chip, EFI instead of BIOS and some other minor thing like a different partition table. Look I honestly have no idea how difficult it is, but besides the TPM chip, the EFI enviroment there's little to search for I guess.. They could make the OS call for all sorts of verification things but they, as far as I know, can be bypassed...

btw, Maxxuss1, any chance you could make a screenshot with this wallpaper;

and have a folder saying 'zizou'

I just love verification xD
