How to change back to Catalina?

My poor Mac Mini 2014 is way too slow on Big Sur.

Mac mini, macOS 11.0

Going back, used to be a lot easier with the older OS X versions.

It is not as straightforward using Recover in the later macOS versions.


You need to have a good backup. (preferable from before you upgraded to Catalina)

You need to startup in macOS Recovery and use Disk Utility to Erase the Internal Drive.

You need to reinstall the earlier macOS version or Restore from an earlier Time Machine backup.
