Just upgraded my M1 Air, loving the new animated wallpapers and lock screen.
My only pet peeve is that the offline phase of the upgrade took a whole 20 minutes - something which no other OS requires - yes, even for Windows, the offline phase of an upgrade is usually in single digits.
So this is something Apple definitely needs to improve upon.
Sure, I mean it’s not a big deal. But it felt a bit odd considering macOS and Apple Silicon usually flies in pretty much every other task, so the lengthy update just felt a bit out of place.
