I INSTALLED MAC OS MONTEREY A FEW DAYS AGO ON MY MAC, AND IT DOESN'T WORK WELL, I NEED TO GO BACK TO BIG SUR, BUT I HAVE NOT BEEN ABLE TO DO IT.
DOES ANYONE KNOW HOW TO DO IT?
DELETE MENTEREY
Installing beta versions on any system that that needs to remain stable and available is... unwise.
Wipe the storage, and perform an install of Big Sur.
You might have to use the Apple Configurator 2 app from another Mac to reset the Mac, if this Mac is M1.
