Coming five days after the second beta, MacOS Mojave 10.14.1 has a new beta build out for developers. The third beta of the first update to Mojave was released yesterday and is available for those who have Mac devices registered in the Apple Developer Program. If you have a registered device, you can download the update via the Software Update feature in Settings.
In normal Apple fashion, very little is known about what is fixed or new in the beta. Apple generally only releases detailed notes on updates when it is released to the general public. When that will happen is not yet known.
We do know that Group FaceTime is coming as it was in the first beta back in September and remains in this beta. That feature, for those that haven’t heard, will allow you to use FaceTime to video and/or voice call with up to 32 friends at the same time. It dropped out of the original MacOS Mojave release about midway through its beta cycle. Additionally, the 70 new emoji that were originally released in iOS 12.0.1 are now in this new beta for testers too.
As always, it is recommend that you not install betas of MacOS Mojave on your production Mac in case there is a major bug discovered. The hint is in the name: It’s beta and you could find a bug or odd behavior that impacts your daily use of your device.
