As well as the new iOS 11.3 beta and the new watchOS beta, Apple also released a new beta for their desktop software, macOS High Sierra 10.13.4 Beta 5. The software is also available for members of Apple’s public beta testing program.
The new macOS High Sierra 10.13.4 Beta 5 is now available to download for registered developers and the software will bring a range of new features to Apple’s Mac range of computers.
The latest version of macOS High Sierra will also include a range of bug fixes and performance improvements for the Mac.
The fifth beta of Apple’s macOS High Sierra 10.13.4 is now available to download from Apple’s developer center. We are expecting the final version of the software to land later this month along with iOS 11.3 and watchOS 4.3.
