On this occasion and almost 24 hours after the other versions of the different Apple OS arrived, the developers have in their hands the new beta version of macos catalina. In this case we are facing the third beta and in it, as always, new features are added focused on the stability and security of the system, bug fixes and little else.
As always, keep in mind that new versions of macOS or any other software requires a time of adaptation and improvements when there are many changes, in this case, in macOS Catalina, the numerous internal changes to the system, the adaptation of the applications to 64 bits and others, is costing a little more than normal.
Clearly the recommendation is that you update to macOS Catalina in its official version, that you stay away from the beta versions for developers and above all that you see that your team and your work tools are compatible with the new Mac operating system and then update.
The news in this new beta 3 for developers is focused on the system and its improvements. The update is important and more so when many users are having failures or problems in their equipment, so it is interesting that Apple is quick to close any failure or problem that they may have and in this case it seems that they are doing so. We may think that the unseen changes are less important but really are the ones that an operating system needs the most to work well and these are the ones they are implementing in these betas.
