Apple has updated its entire suite of operating systems, shipping updates macOS High Sierra 10.13.3, iOS 11.2.5, watchOS 4.2.2, and tvOS 11.2.5 to the public on Tuesday.
The updates come after a few days of testing with the previous beta releases, and a month-long testing cycle overall. The iOS and watchOS versions are unchanged from the last beta. Both macOS High Sierra 10.13.3 and tvOS have small increments, suggesting a few changes since the last beta release but not many.
The updates are “sub-point” releases, so it remains unlikely that major new features are coming to the updates. Apple usually keeps small version increments limited to bug fixes and small tweaks —including some fixes for the “Meltdown” and “Spectre” vulnerabilities.
All users can get the patches through the software update feature on the devices. Users with an iPhone, iPad, or Apple TV get them through the Settings menu, with macOS users getting them through the Mac App Store. Apple Watch owners perform the update through a linked iPhone.
