After some of the early warnings I waited awhile on Big Sur. Finally installed it yesterday, some observations.
First, generally, overall, I am pleased. I probably should have read up on things some more before I did it, so that maybe the UI changes wouldn’t have been so surprising, but I like the look and feel of it so far.
Some things that were different
My menu bar utility (Dozer) I had been using to hide less-used items is not working well. Everything is spaced out farther than before, including the two dots that Dozer uses. I hope I can find a fix for this…
Some things, mostly utilities, that were previously set to always start didn’t start - Skitch, ToothFairy, all seem to work after a manual start.
Oddly, the desktop wallpaper was still Catalina - managed to find the Big Sur wallpaper and switch it out manually.
Things that just work
Alfred, Keyboard Maestro - no problems - same for Notion, FastMail, Firefox, Safari
Sorry, nothing more profound than that. It’s just working, so that’s good.
