Time Machine Does Not Delete Old Backups to Make Space for New.
I use an external drive for Time Machine. It used to delete the oldest backup to make space for a new backup. In October 2019, it quit doing this and gave me a message that said "Backup Failed. There isn't enough space on 'My Passport for Mac'". How can I get Time Machine to delete the oldest backup and backup my computer again?
iMac, macOS 10.13
