Apple has released the fifth beta of MacOS Mojave 10.14.1 to beta testers, the day after iOS 12.1 had its fifth beta released. The update, for those who are registered in the beta program, is available in Settings>System Updates. The new build is version 18B73a for those keeping score at home.
As is normal for these beta releases, Apple offers no release notes for them and there is little known about what they contain. However, given where we are in the beta cycle for 10.14.1, Apple is likely in the “fit and finish” phase where they are making sure everything is cleaned up and working properly. With the Apple event next week expected to announce updated and new Macs, the release of this update is likely close at hand.
What we do know of course is that MacOS Mojave 10.14.1 will support 70 new emoji and will have Group FaceTime. Group FaceTime will allow you to video or audio FaceTime with up to 32 people at once, providing an ad-hoc conferencing solution. This new feature will be supported by iOS 12.1 and WatchOS 5.1, both of which are also in the latter stages of their beta testing.
As always, it is not recommended that you install the MacOS Mojave 10.14.1 beta on your “daily driver” Mac as unexpected bugs or issues can pop up that cause issues for your daily needs.
