Beta 4 of MacOS 10.12.5, iOS 10.3.2, tvOS 10.2.1, watchOS 3.2.2 Available
Apple has released the fourth beta versions of macOS 10.12.5, iOS 10.3.2, watchOS 3.2.2, and tvOS 10.2.1.
No major new changes are expected in the beta releases, as the builds likely continue to focus on bug fixes and security enhancements.
MacOS 10.12.5 beta 4, iOS 10.3.2 beta 4, WatchOS 3.2.2 beta 4, and TVOS 10.2.1 beta 4 are all available now for users who are participating in the beta testing programs. The latest versions can be downloaded now through the respective software update mechanisms in each OS, typically though the Settings app or the Mac App Store.
Apple typically goes through several beta versions of software updates before unveiling a final version of that system software to the public. A fourth beta would usually be a bit beyond the halfway point of beta testing, offering a vague idea of when the final releases might be issued.
