I used to have a Time Capsule. But I was having issues with it, plus most everything is backed up to iCloud now, so I replaced it with a new Airport Base Station (without the built in Time Capsule).
I then went into Time Machine preferences to turn it off so it wouldn’t continue to try backing up but there’s no on/off switch. I’m almost certain there was in older versions of MacOS. Instead there’s a box next to “Back Up Automatically.” So I unchecked it thinking that would do it.
But now I keep getting notifications that I haven’t backed up in so many days, or that the last back up didn’t finish. I’ve tried going into “Select Disk” to see if I can unselect the old one, but no luck.
How do I tell Time Machine to stop trying, or to turn it off completely?
