As a watch, Apple continues to update trial versions of its newest operating systems. One week after Friday, we are already among the seventh beta versions of iOS 13 (compilation 17A5565b) of iPadOS 13 (same compilation), from watchOS 6 (17R5566a) and the tvOS 13 (17J5557a).
Interestingly, the macOS Catalina Still out of the list: The future operating system of the Macs has not yet won a trial version in August. Its last beta was the fifth, released on the last day of July. Is the system already so round that it needs no further testing? I tend to doubt, but we'll see.
The aforementioned beta betas are currently available only to Apple Developer registered developers. The public trial versions (except watchOS, which is not part of the program) should be released in the next few days on the Apple Beta Software Program and we will, of course, advise you of everything here.
Who is already testing? Any interesting news?
