Can you downgrade macOS? Yes, it is possible. If you have already backed up the previous versions with Time Machine or have an installer for macOS Monterey/Big Sur, you can simply downgrade macOS with the previous ones easily. Of course, you have to back up the files beforehand. But you cannot always make sure all files are preserved, especially for using a previous installer.
