After a false start yesterday, a second beta of MacOS Mojave 10.14.2 was released by Apple this morning. While it is technically the second beta, it for all intents and purposes is the first. Yesterday, the first .2 build was online for just a handful of minutes before mysteriously being pulled by Apple. The Cupertino company never gave an official reason why the first build was pulled but it probably doesn’t matter much now given a replacement is out for it.
As for the build itself, the main focus of it is to address bugs and performance issues. There are not any new features of note (at least none found yet) and there aren’t any expected with this release. The interpretation readers: Maintenance Build.
Apple has been keeping a rapid pace going on all of their major and minor updates over the past year and it looks like that trend is going to continue. Assuming that we have the normal 4-6 beta build cycle for this .2 build, it is likely we will see it before the end of the year. Best case, it could be out at the end of this month. More than likely, it will be a mid-to-late December release.
Right now this MacOS Mojave 10.14.2 beta is only for registered developers. More than likely we will see it hit the public Apple Beta Program channel later today or tomorrow.
