macOS High Sierra 10.13.3 beta 2 was released by Apple last night, those from Cupertino finally starting the testing process of the future major update for Macs. Officially, Apple hasn't said what changes they implemented in macOS High Sierra 10.13.3 beta 2, but we can expect what we usually get.
macOS High Sierra 10.13.3 beta 2 is most likely to improve the general performance of the operating system and to solve some performance problems of the previous version. Of course, this does not mean that Apple will avoid offering a final version without vulnerabilities that allow obtaining administrator rights without a password, but we could be surprised.
macOS High Sierra 10.13.3 beta 2 can currently only be installed by application developers for the macOS platform, and a public beta should be available soon.
