Apple has seeded the third beta of MacOS Mojave 10.14.5 to registered developer testers. The updated build is 18F118d for those keeping score at home. As of this post, the beta bits had not been released to those registered in the Apple Beta Program, the public testing program.
For those registered in the Apple Beta Program, you shouldn’t have to wait much longer for MacOS Mojave 10.14.5. Apple tends to release the public beta later on the same day or within a few days of developers getting it. This new beta comes about two weeks after the second beta was released.
Like the first two betas, there are no new features in this build of macOS Mojave. Instead, this release is primarily focused on bug fixes, security improvements, and overall performance updates. That doesn’t necessarily mean there will not be new features by the time this version is released to the public. It just means, for now, that’s not the focus for the folks in Cupertino.
One of the early debates with version 10.14.5 was if we would see the new Apple TV app arrive with its release. It is increasingly looking like that will not be the case. With Apple focused on Marzipan, it is likely we will see the ported Apple TV app in macOS 10.15. That should be released later in 2019, likely in the September/October time frame.
