When I upgraded my MBA to Sonoma, it was unusable for about 3-4 days. Opening Finder would slow the system down to a halt and eventually crash.

I have no idea what the problem was, but it eventually sorted itself out after that (not before I was ready to wipe it all and start again, despite how uninterested I was in doing that). Search engines and GPT didn’t give me much - Spotlight reindexing was everyone’s best guess, but I saw no evidence of this.

The fact that I’d transitioned to putting all my dev work into iCloud didn’t help - I moved out of that pretty shortly after, iCloud really doesn’t like files changing that often.

The UX on macOS is still my favourite across all the OSs I’ve used for personal use. But when it stops working … it’s impossible to figure out why and impossible to do anything about it except wait and hope, or start over.
