Apple releases iOS 10.2.1, watchOS 3.1.3, tvOS 10.1.1, and macOS Sierra 10.12.3 with bug fixes and improvements

Apple on Monday released several updates for its various platforms. iOS 10.2.1 is out for iPhones and iPads, tvOS 10.1.1 for fourth-gen Apple TVs, watchOS 3.1.3 for Apple Watches, and macOS Sierra 10.12.3 for Macs. All of the updates can be installed via their respective OTA mechanisms, or you can grab the standalone packages from our Downloads page.

There’s not much to talk about here in terms of new features or user-facing changes. These updates were mostly focused on under-the-hood stuff. As you see in the above screenshots, iOS 10.2.1 “includes bug fixes and improves the security of your iPhone or iPad,” and WatchOS 3.1.3 “includes improvements and bug fixes.” Here’s the macOS 10.12.3 change log:

  • Improves automatic graphics switching on MacBook Pro (15 inch, October 2016)
  • Resolves graphics issues while encoding Adobe Premiere Pro projects on MacBook Pro with Touch Bar (13 and 15 inch, October 2016)
  • Fixes an issue that prevented the searching of scanned PDF documents in Preview

As usual, we’ll update this post if we receive new information or spot additional changes worth noting.
