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

   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. Given the security focus of these updates, we encourage
   you to update soon, but wait a week or so to make sure that they don't
   suffer from unanticipated side effects. As always, back up your data
   first!

   macOS 10.12.6 -- [1]macOS 10.12.6 Sierra is available via Software
   Update, where it's an 819 MB download. Alternatively, you can instead
   download a 1.98 GB [2]combo updater to update from any version of
   10.12.

   In addition to unspecified bug fixes, 10.12.6 includes the following
   enterprise-focused changes:
     * Resolves an issue that prevented making certain SMB connections
       from the Finder
     * Fixes an issue that caused Xsan clients to unexpectedly restart
       when moving a file within a relation point on a Quantum StorNext
       File System
     * Improves the stability of the Terminal app

   macOS 10.12.6 includes [3]24 security fixes.

   iOS 10.3.3 -- You can install the iOS 10.3.3 update via Settings >
   General > Software Update or through iTunes. It too features [4]24
   security fixes 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 [5]10 security fixes.

   tvOS 10.2.2 -- Finally, Apple released tvOS 10.2.2, which includes
   [6]15 security fixes. 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.
