Apple releases iOS 10.2.1, macOS Sierra 10.12.3, tvOS 10.1.1 and watchOS 3.1.3 -- here's what's new

Apple today releases updates for all its major operating systems, introducing iOS 10.2.1, macOS Sierra 10.12.3, tvOS 10.1.1 and watchOS 3.1.3. The latest builds do not add any new features, as the focus is on improving the existing functionality and squashing bugs.

Mac users are treated with the lengthiest changelog, and users of the latest MacBook Pros (October 2016 models) should be particularly interested in it. That's because Apple improved graphics switching on the 15-inch MacBook Pro and fixed graphics issues that occurred while using Adobe Premiere Pro to encode projects on both 13-inch and 15-inch Touch Bar-equipped MacBook Pros.

But that is not all that macOS Sierra 10.12.3 brings to the table. Apple also resolved a problem that prevented users from searching scanned PDFs in the Preview app, solved a compatibility issue related to exporting encrypted PDF documents, fixed a problem that prevented a number of third-party apps from importing photos from cameras properly, and, on the enterprise side, it also eliminated an issue that had cached or network user accounts disabled when the maxFailedLoginAttempts password policy was used.

On the iOS side of things, iOS 10.2.1 is a minor release, only introducing security improvements -- which Apple lists on this page here -- and bug fixes. Same goes for tvOS 10.1.1 and watchOS 3.1.3, for which there are no major changes listed. We can only assume that we are looking at a number of bug fixes and small improvements.

All the aforementioned OS updates are available to download right now over the air.
