MacOS Sierra 10.12.5 Update Released
Apple has released MacOS Sierra 10.12.5 for Mac users. The small point release update to Sierra includes security updates and bug fixes, and is therefore recommended to install for all users running a prior MacOS Sierra build.
A separate security update release is available for Mac users running OS X El Capitan and Yosemite.
Separately from the Mac OS update, Apple has released iOS 10.3.2 for iPhone and iPad, watchOS 3.2.2 for Apple Watch, and tvOS 10.2.1 for Apple TV.
Always back up a Mac before installing any system software update. Backing up via Time Machine is easy and recommended.
