Mac air book WD drive not backing up is it because I am now on Monterey?
My WD external drive has stopped backing up my Mac Book Air. Is this because I have updated my system to Monterey?
MacBook Air 13″, macOS 12.7
What app or service are you using to do your backups? Is it Time Machine? If so, have you confirmed in the Options in the Time Machine settings that the external drive is not in the "excluded" list?
