Apple has provided its fourth beta of macOS 10.14.1 Mojave to developers for testing, arriving two days after developer betas for its iOS, watchOS, and tvOS counterparts.
The latest builds for Apple's operating systems are available to download via the Apple Developer Center for those enrolled into the test program, or can be installed directly on a Mac running the beta software by going to the "Software Update" facility in System Preferences. Public beta releases are usually made available after the developer versions, and can be updated the same way, or downloaded from the Apple Beta Software Program website.
The fourth macOS 10.14.1 Mojave build is 18B67a, up from the third beta's build, 18B57c.
Apple has provided relatively few details about the contents of the beta builds so far, but there are some confirmed additions. Chief among the features is the return of Group FaceTime, which enables up to 32 people to be involved in the same video conference, after it was pulled from the macOS 10.14 betas just before its public release.
Social users will also benefit from the inclusion of 70 new emoji, including one that recently received some unexpected controversy. While largely included for iOS 12.1, the same emoji will also need to be in macOS and Apple's other operating systems that offer messaging services and similar features that use the symbols.
AppleInsider, and Apple itself, warn users away from installing beta releases on primary or mission-critical hardware, due to the possibility of a loss of data or other issues. Users wishing to try out the betas should install them on non-essential devices, and to retain backups of their data before setting it up or performing updates.
