My mid-2011 mac mini died very suddenly. It was working fine and an hour later it wasn’t. In all fairness, I was getting steady appearances of the dreaded SPOD all day, but no error messages. I had planned to shutdown and restart before I went to bed to see if that would fix the SPOD, but the computer had already died by then.
I took it into the Apple store near me and was informed that they no longer repaired anything that old and to try a 3rd party. In the interim I bought a new Macbook Air (that seems excellent).
I took it home, plugged it into my Time machine and was informed that the most current backup was 12/11/2018! The time machine had been plugged in to the mac mini and should have been backing up automatically every hour. Apparently it wasn’t, and again - there were no error messages.
I restored what I could and all seems well. I’m just wondering why I had this trouble and how can I check in the future if TM isn’t doing it’s job? Is it just a question of clicking the “Clock” icon repeatedly and seeing that the backups are happening as they should be? Or should I be entering Time Machine and seeing if the days are OK? Or…
