https://techcrunch.com/2017/09/12/macos-high-sierra-release-date/ >Apple has been hard at work on four different operating systems — iOS, tvOS, watchOS and macOS. And the company just updated its website after its iPhone launch event. It now says that macOS High Sierra is going to come out on September 25. >macOS didn’t get any love this time around as the company didn’t even mention High Sierra once. Maybe there wasn’t enough time. Or maybe there wasn’t anything new to share beside a new release date.
