@Judobeing I have now upgraded my 2012 Mini to Big Sur using
Patched Sur
Patched Sur only works as an in-place upgrade rather than a clean install (I usually prefer clean!).
I'd recommend performing a Web restore and restore the Mac to it's default OS (Mountain Lion for me!).
Then follow the instructions, ensuring to select EFI boot, wait for Mac to turn off and then turn on again and select the Big Sur install disk on the boot screen.
Doing it this way, the Mountain Lion install was not bloated with apps and files.
Everything seems to be working well, Logic and my Native Instruments Komplete software is working just as well as it was on Catalina!
Hope this helps!
