The first developer beta versions of macOS Mojave 10.14.4, iOS 12.2, watchOS 5.2, and tvOS 12.2 are now available. Apple hasn't been long since the final versions were released for all users and the developers already have the first beta versions available.
In this case, the versions have just been released and we will be waiting for the improvements that are included in them despite the fact that the previous versions officially released only solved errors. These new betas have all the earmarks of being the same in this regard. We will see with the passage of the afternoon if they really add any outstanding novelty, in principle it seems that they do not.
macOS Mojave 10.14.4 continues firm and stable step towards the WWDC without significant changes in its operation, but the rest do not seem to add substantial improvements or notable changes in the operation of the system either. Apple is saving news at this point and there may not be too many added until the next switch to macOS 10.15 or even until summer.
We are pending of the possible novelties that appear and in the case of having an outstanding one, we will update this same article or directly publish a new one. At the moment what we have are beta versions for all Apple devices, Macs, iPhone, iPad, Apple Watch and Apple TV.
