Update: iTunes 12.5.5 was also released today.
Apple gave us four updates for our iDevices and Macs today.
Earlier this afternoon, MacOS Sierra 10.12.3 arrived offering graphics improvements for the October 2016 edition MacBook Pros. The Sierra 10.12.3 update closed up a hole in Preview that was mucking with searching scanned PDF files.
iTunes 12.5.5 was also released for MacOS (and Windows PC) adding "minor app and performance improvements".
Also arriving today was 10.2.1, a minor security and bug fix update for iPhone and iPad. watchOS 3.1.3 tagged along to give Apple Watch owners a small tune up also.
And, last, but not least, Apple TV got a minor bump up to tvOS 10.1.1 from 10.1.
All of today's updates are minor security and bug fixes, with no major features or new functionality added.
Look for the iOS 10.3 beta releases to start arriving any day now.
