We have here the first beta of the year 2017 for the operating system macOS Sierra 10.12.3 released by Apple for developers. In this case, it is beta 3 for macOS Sierra 10.12.3 and as in previous beta versions the improvements that are incorporated are not added in the description apart from improvements in system stability and security improvements in macOS.
Apple kicks off the day that celebrates the 10th anniversary of the presentation of the iPhone with all the new beta versions for developers, both macOS Sierra and iOS, watchOS and tvOS.
If there is any outstanding news in this new version, we will publish it directly in this article or if it is of importance we will create a new one. In any case, what we have on the table looks like bug fixes on the previous beta version and we don't expect big changes in this regard. Apple is quite clear that in these versions it has to polish security and stability details, something that although it is true we can say that it has been doing since the first versions of macOS Sierra, it would have to press a little more. In any case it is good that the beta are coming out at a good pace, but hopefully the improvements will be noticed in these final versions.
On the other hand, it should be noted that we are still waiting for the final version that they removed from watchOS due to stability issues, but Apple seems to have forgotten that it has to release that new version and is releasing beta versions of the new 3.1.3 for developers. We imagine it will soon be available to all Apple Watch users ..
