I got two MacMinis 6.2 late 2012, that are limited to Catalina, but want to use Live12 on macOS 11 or newer.
So got the latest OpenCore-Legacy-GUI patcher and followed the steps and can boot the BigSur installer from USB, but can't select a drive to install "This update cannot be installed on this computer". APFS and GUID is present which should be correct. The computer is according to OpenCore supported and has a profile for the Mini6.2.
I am stumbling over the "this UPDATE" part. Do I have to wipe the disk or does anyone know why it won't install?

Did you try to format a disk from Disk utility on the installer? I guess both HFS+ and APFS should work.

 

Are you sure you're using OpenCore Legacy? https://dortania.github.io/OpenCore-Legacy-Patcher/

 

I have deleted the partitions and formatted to APFS, but still the same. I don't know why the installer still says "update", but maybe that's normal. The installer shows if something isn't right like wrong filesystem or GUID missing.

 

Yup, that one. Tried it with BigSur 11.0.1 and also downloaded a newer version with the patcher.
