Today is one of those days in which Apple releases a new update for every single operating system in its stable. We’re talking about iOS, watchOS, tvOS, as well as macOS, so regardless of which Apple device you have, an update is likely waiting for you in the relevant section of the OS as you read this.
iOS 10.3.3 brings with it bug fixes and performance enhancements, as well as better stability all-round. No new features are in this time around. The story is similar for watchOS 3.2.3, which can be installed on your Apple Watch through the Watch app on iPhone.
Unsurprisingly, tvOS 10.2.2 for the fourth generation Apple TV is all about bug fixes, performance improvements, and enhanced security too. You’re obviously noticing a trend by now, and macOS Sierra 10.12.6 isn’t the release to buck that. Yes, this one is minor as well, with no user-facing novelties to speak of. Despite all that, you should definitely keep your devices up to date, if only to avoid a security scare or two.
