After panicking, the 3rd Apple Support Representative and I endeavoured to try and reset the System Management Controller (SMC) [1] once again. At this point I had realised that the first few times that I tried this with a previous support representative would not have worked, as I was holding shift on the left-hand side of the keyboard (the previous support representative did not specify) and not the right-hand side as outlined in the support article for Macs with the T2 chip.
Good luck!
Upgrading to a new OS on release day without a prior backup. You like to live dangerously, do you?
Actually I never upgraded to Catalina and waited until Big Sur seemed stable enough to upgrade to and it upgraded from Mojave without a hitch. I had been following the beta releases of Monterey and it seemed pretty solid, so I figured what the heck, let’s live dangerously baby!
As for not having a recent backup it’s just something that always gets put the back burner. That’s my failing. But to be honest, I wouldn’t have really lost anything of worth, everything important is in version control. Maybe I would have lost a few dot files, some configs, some PoCs, the grooves in my couch. Those grooves that I’ve cultivated wouldn’t cost me much time and honestly sometimes it’s good to get a fresh couch and re-evaluate the grooves of the past.
With all of that said, despite the inconvenience of the upgrade, I would love to give a shout out to Apple support. It’s these moments that you get to appreciate the fact that you can pick up the phone and talk to someone who has some outstanding fault finding and problem solving abilities, leagues ahead of any other provider I have ever had experience with.
