This afternoon macOS Sierra 4 beta 10.12.6 was released for developers. The truth is that we are all looking forward to the public version of macOS High Sierra and I am not lying if I say that we are all more aware of it than of the current version of the Mac OS. In any case, the beta versions are advancing at a good pace and it is possible that you are implemented improvements in the operation of the system with typical bug fixes included is the little that remains to be added to macOS Sierra before the jump to the new operating system presented by Apple on June 5 at WWDC.
We have been a while in which beta versions provide those bug fixes and little else, so we can not say that the news is highlighted. On the other hand we already want to try some of the new features of the next macOS and that is why we all look forward to the public beta of the new version than the current one.
As always, it is better to stay out of these beta versions if you are not a developer until the public version is released, since we could have some incompatibility problem with applications or work tools. The beta versions released are usually stable and to date they have been, they do not show errors that affect the functionality of the system or the like, but we must not forget that they are beta versions and it is better to be cautious with them even though they show a lot stable and do not add new features in functionality that may affect the operation of the Mac.
