Follow up on the release to the developer community last week, Apple has now released the first beta of MacOS Mojave 10.14.4 to public testers registered in the Apple Beta Program. The release is ready to download now and can be accessed by going to System Preferences>Software Update on your Mac that is registered in the program.
MacOS Mojave 10.14.4 will have some new features in addition to those fixes and updates. One such new feature is Apple News for those of you in Canada. The localized version of News is available both in English and French. Apple notes that, during the beta testing, the Apple News app won’t be updated as frequently as it is for those in the US, UK, and Australia where the service has already been released.
As for when we can expect MacOS 10.14.4 to be released to the general public, that is not clear. Apple does not post a release schedule for their updates to MacOS so it is a bit of a guessing game. Based on historical beta cycles the company has for the platform, we can probably expect a release sometime between four to six weeks from now. That, of course, can change should a major bug be found during the beta testing cycles.
Finally, Average Apple Guy does not recommend installing beta software on your primary Mac.
