Apple today released another batch of beta versions of its operating systems which are expected to be released to the general public in September / October. Just them: iOS 12 beta 9 (build 16A5362a), macOS Mojave 10.14 beta 8 (18A371a), watchOS 5 beta 8 (16R5357a) and tvOS 12 beta 8 (16J5355a).
Note that iOS 12 is a beta version in front of the rest. That's because, last week, Apple released beta 7 but had to shut it down due to system performance issues; a few days later, however, she released the eighth test version of iOS 12 fixing the problem. Then, at least for now, things (numerically speaking) will be out of step.
Soon, the new test builds for iOS 12, macOS 10.14 and tvOS 12 should also paint the watchOS as the only system that is not part of public tests in the Apple Beta Software Program.
To those who are already testing, share your experiences on these new builds in the comments below! ?
