Continuing to work like a Swiss watch, Apple today released a week after its last updates the fourth test versions of iOS 11.4.1 (compilation 15G5074a), from macOS High Sierra 10.13.6 (17G54a) and the tvOS 11.4.1 (15M5072a). In addition, the third beta version of the watchOS 4.3.2 (15U5069a).
As we have said, it is natural for Apple to continue working on sub-versions of the current systems, since the new ones (iOS 12, macOS Mojave 10.14, watchOS 5 and tvOS 12) will still need a few months of testing before they are ready for the general public.
There is no news of big news in these small updates, which should only focus on bug fixes and small performance improvements. If something interesting comes up in any of the updates, of course, we will be looking forward to notifying you. ?
