Apple will release the final version of its desktop operating system – macOS Mojave – on the 24th of this month. Get your Mac ready right away.

Staying true to its trend of releasing its desktop operating system later than usual, Apple has revealed that macOS Mojave will be released on the 24th of September, which is at the end of this month. But the good news is: the macOS Mojave GM (Gold Master) build will be available to developers and public beta testers today, which is the release candidate of the final version. If last minute bugs pop up, Apple will be forced to release a slightly updated version of its desktop OS as the final build. But we’re hoping that won’t be the case.
