Just three days after releasing the third beta version of macOS Sierra 10.12.3, Apple today released the fourth (build 16D30a).
According to the release notes of the new version, the update improves the stability, compatibility and security of macOS (there is nothing less in particular). On the floor of the carriage, it should not be long before this version is released to the general public due to the bug in Safari that was recently discovered.
For now the update is only available to developers, but in a little while it should also paint Apple Beta Software Program

Apple also released the fourth test version of iOS 10.2.1 (compilation 14D27).
Like macOS and the other systems that are in beta, no big news is expected for it. There is an expectation, however, that Apple will soon make available the first beta version of iOS 10.3 this one, yes, with a supposed novelty called ?Theater? mode.
wait to see just like macOS 10.12.3 beta 4, iOS 10.2.1 beta 4 should be painting very soon in the Apple Beta Software Program.
