EMERGENCY: Time machine seems to be backed up, but will not move to older backups
I can see the current window in the front, and the dates on the side indicate backups for exactly the length I would expect since I set it up (around a month), but I cannot click on any previous date and the arrows do not show me older "versions."
Meanwhile, I need a missing file for work right away. Any ideas?
Note: I am backing up Time Machine to two drives, which is something you can choose in the settings. Could this be the problem?
