If you have recently installed MacOS Monterey and regret doing so for whatever reason, perhaps incompatibility with some critical applications, general instability, or experiencing some other problems with MacOS Monterey that make it unworkable for you, you may be interested in downgrading from MacOS Monterey back to macOS Big Sur, or whatever the prior macOS release was.
Downgrading macOS Monterey involves erasing the Mac, reinstalling macOS, and then using Time Machine to restore the data, and that is the method we will cover here. The process is a bit different on Intel Macs versus Apple Silicon Macs.
If you don’t have a Time Machine backup available from before you updated to macOS Monterey, do not proceed.
As Monterey was/is my OS from the day I bought it. Boondabah
