re: Apple Core Rot
Apple software updates keep getting scarier (inscrutable progress, multiple reboots), and taking long and longer, even for minor updates.
So far my 2019 Mac Pro has rebooted four or five times. I don’t yet know if the update has destroyed my boot drive, or whether it will succeed. It’s doing something now yet again (“8 minutes remaining”). Another reboot and maybe it will be OK?
UPDATE: it ultimately worked.
Surely Apple indicate with each reboot that it’s not just in an endless bugfest loop.
