I had to boot into safe mode to log in to iCloud, to get an auth code from a device I removed months ago, just to remove the notification flag that said I needed to log in to use certain apps.

I don't get how they can keep making buggy OS upgrades like this. I mean is the wealthiest company in the world too cheap to hire a good QA team? Or do they just assume those who bitch on their forums are their QA team?
