Apple launches OS X El Capitan 4 beta 10.11.2 punctual to the appointment on Tuesdays. In this case, the new beta has build 15C47a and is already available in the Apple Developer Center for download by developers.
As in the previous beta versions, Apple asks developers to focus their efforts on observing the proper functioning of WiFi connectivity, graphics, the native Mail application, Calendar, the Photos and Notes application in addition to Spotlight. . Improvements in the performance and stability of the system are Apple's priority and they are focusing on this as much as possible, leaving aside the contribution of new features in these beta versions.
It is expected that for tomorrow if everything is fine in this beta 4 version released a few minutes ago, the Cupertino company will launch the same version of this OS X El Capitan 10.11.2 (with another beta number) for the group of users that they are wrapped in the public beta program.
On the other hand, it is expected that Apple will also launch the beta of iOS 9 today so we imagine that if they do not do it while we are writing this article, it will lack little. Apple continues to improve operating systems through minor tweaks that are hardly noticeable to most users, but system stability and fluidity seem to be a priority at Apple right now.
