My Passport / Time Machine
I am having difficulty backing up my MacBook Pro through Time Machine. It worked fine for nine months and stopped doing backups December 8th. Now it asks for my password to access "Backups of Carole's MacBook Pro". I don't know the password. It gives no alternative for "forgot password". Just cancel or enter. I need to back it up somehow so I can take it in for tech support. Help!
MacBook Pro 13″, macOS 12.0
