Apple Releases macOS 10.12.6, iOS 10.3.3, watchOS 3.2.3, and tvOS 10.2.2

by Josh Centers

Apple has released bug fix and security updates for all of its operating systems. The company didn’t list any new features in the release notes. These updates fix the BroadPwn vulnerability (see “iOS 10.3.3 Patches High-Profile BroadPwn Flaw [1],” 21 July 2017), so we recommend updating as soon as possible. As always, back up your data first!

macOS 10.12.6 -- macOS 10.12.6 Sierra [2] is available via Software Update, where it’s an 819 MB download. Alternatively, you can instead download a 1.98 GB combo updater [3] to update from any version of 10.12.

In addition to unspecified bug fixes, 10.12.6 includes the following enterprise-focused changes:

macOS 10.12.6 includes 24 security fixes [4].

iOS 10.3.3 -- You can install the iOS 10.3.3 update via Settings > General > Software Update or through iTunes. It too features 24 security fixes [5] and ranges in size from 80 MB to 140 MB.

watchOS 3.2.3 -- watchOS 3.2.3 is a 26.1 MB update that you install via the Watch app on your iPhone (in Watch > Settings > General > Software Update). Remember that the Apple Watch must be on its charger, charged to at least 50 percent, and within range of your iPhone, which itself must be on Wi-Fi. Don’t start installing if you’ll want to use the watch again within an hour or so — watchOS updates take surprisingly long to load. watchOS 3.2.3 includes 10 security fixes [6].

tvOS 10.2.2 -- Finally, Apple released tvOS 10.2.2, which includes 15 security fixes [7]. If your fourth-generation Apple TV isn’t set to update automatically, you can get tvOS 10.2.2 via Settings > System > Software Updates > Update Software.
