Time Machine couldn't complete backup I get the above notice indicating Time Machine couldn't complete the backup because the backup disk is read-only. It was working just fine until I installed the latest OS (Monterey Version 12.5) The message says the disk is read only. It was backing up fine until installation new OS. Any ideas? What should I do? I'm not a techie.
