Well, computer goes to the Apple Store tomorrow. My senior tech exhausted everything he could do. We did get the desktop for Big Sur as a test user, but it just won't find the Time Capsule back-ups. Again, in disc utility it does look like all my stuff IS on the hard drive, so hopefully they can extract from that or the Time Machine. I have to bring both things so hopefully they can extract from Time Machine while I'm there so I can bring it back home to use as my router, otherwise I'll have to buy a new router and hope I can figure out how to set it up because I can't get on the wireless from the guy in the back house - too far. So, probably another sleepless night, and I'm cancelling tomorrow's noon rehearsal.
