Apple this week began rolling out the third beta build of macOS Mojave 10.14.4 to both developers and public beta testers. This comes a couple of weeks after the second beta was released.
The new build can be installed by heading over to the System Preferences section of the Settings app. From there, hit “Software Update” and you should spot the upgrade ready to be download. Hit download and wait for it to finish installing. You’ll want to plug in your MacBook before installing the update to ensure you don’t run out of juice. Otherwise, sit back and be patient.
macOS 10.14.4 will likely include mainly bug fixes, security improvements, and other under-the-hood enhancements. Therefore, don’t expect to see any user-facing changes once the software is installed. That being said, if anything significant is discovered, we’ll let you know.
