Three weeks after the release of macOS Mojave 10.14.1, in which new emoji and FaceTime group call support appeared, Apple introduced version 10.14.2.
The release note does not indicate any global innovations. Apple limited itself to the traditional “fixing bugs and improving system performance.”
In macOS, Mojave 10.14.2 added support for RTT (Real-Time Text) when making calls over Wi-Fi, and also fixed the iTunes error , due to which the player refused to play music on third-party speakers supporting AirPlay.
You can download the update in the Settings -> Software Update menu. This item of the system just appeared in the OS Mojave. The size of the update varies from 2 to 3 GB, depending on the Mac model.
