If you own an iPhone X or later and have gone out into the world recently, you probably noticed an unfortunate side effect of the new mask-wearing culture: Face ID doesn't work. It is more of a feature than a bug, but the fact of the matter is that if Apple's True Depth camera system can't scan your whole face, it won't unlock your phone. If you're wearing a mask like most stores and restaurants require, you're left typing in your passcode whenever you want to check your shopping list or pay your bill. Apple offered up a workaround with the recent iOS 13.5 update, but it's hardly a fix. Now, instead of waiting for Face ID to fail a couple times before the passcode screen pops up, you can swipe up from the bottom of the screen to quickly enter your code.

This is almost like part two of my macOS Sierra review. I had a chance to test Apple's newest desktop operating system at the beginning of the summer, just before it was released in a public beta. The software hasn't changed much since, but a few of the headline features were missing from that earlier build; Apple said they wouldn't be available until the final version shipped in the fall. As it happens, Sierra arrives today as a free upgrade, so I'm picking up right where I left off. What follows is my full review of Sierra, though if you read my earlier preview, or have been using the software yourself, you won't find many big surprises here.
