Time Machine Autobackup Not Working
I can manually initiate Time Machine backups for my vintage 27" intel iMac - but auto backups just don't happen so often I have weeks between backups as I forget to check. The manual backups are fine and seem to complete properly. I have the same problem on both backup disks. This problem has been going on for ages - I've just got fed up with living with it!
Any ideas on what's up? All help welcome!
iMac 27″, macOS 12.1
