Apple has released the seventh beta of macOS Mojave to developers.
At the time of writing, no new features or changes had been discovered - but we will update this article if any are found. One change is the removal of Group FaceTime (also in iOS 12 too) - Apple have said the feature has been removed for now and would be back in a future release of macOS Mojave.
The official release of Mojave is nearing, and Apple is working quite hard, releasing betas every week, with more performance improvements and bug fixes. More when we get it.
