In the blink of an eye we already have the macOS Mojave 4 beta 10.14.3 in the hands of developers and is that the beta 3 version of macOS that was launched last Tuesday has become obsolete today. In this case, it has been in the hands of the developers for no more than three days and there is already a new version.
It therefore seems that some problem has been detected in the previous beta version and it is that the launch of two versions so in a row is not usual. In this case we also have public beta version available for users who are registered in the beta program, so we are served this week with the betas.
At the moment it is a very recent launch and No. there is data about the news or corrections that have been added in this new beta version, but what is clear is that in addition to macOS they have also launched the beta version of iOS and this is undoubtedly a slightly unusual move in the launch of beta versions.
In any case, we will be attentive to possible news or changes that may have been implemented in these new beta versions, of which Apple Watch and Apple TV have been left out for the moment. As we always say with beta versions, it is best to install them on computers that we are not going to use as primary in case a problem arises, we can also install these new beta versions on an external partition but we should avoid installing them on computers that we need for our day to day .
