Apple has released this afternoon the Golden Master beta of MacOS High Sierra. It should be the last version, with all the errors tuned, that is presented to the developers so that they give the approval and do not find any more failure to solve.
In some very isolated cases has happened, which forces Apple to launch a second Golden Master to the developers, but basically, we should be before the last previous version of macOS High Sierra before its official launch on September 25.
Unrestricted, for everyone
This time Apple has launched the MacOS High Sierra Golden Master for both the developer community and the general public.
That means that from Cupertino they are quite confident that this is the final version of the system, and that their behavior should already be very close to that of the final version that we will see in two weeks.
Still, if you want stability and performance guaranteed by Apple it is best to wait eleven days to download the stable version from the Mac App Store.
If you already have a previous beta installed, you can upgrade to the Golden Master from the same site.
