iCloud is still syncing with iCloud
Setting up a new M2 Ultra Mac Studio (review: it is nice) has revealed a whole new crop of WTFs in the onboarding process (Setup Assistant no longer encourages enabling FileVault? What?) and offboarding process (this screen has been sitting here for hours as I wait to wipe my previous Mac).
Super neat experience so far.
UPDATE: two more neat screenshots. Free of charge.
