Continuing the batch of updates, the Cupertino company today launched the fourth beta of OS X 10.11.6 El Capitan for developers and beta testers, a week after launching the third beta of OS X 10.11.6 and more one month after the public release of OS X 10.11.5. OS X 10.11.6 is undergoing tests since 23 May.
The fourth update of OS X 10.11.6 beta can be downloaded through the Apple Developer Center or the software update mechanism in Mac App Store.
No news about the new beta of OS X El Capitan, so probably this fourth version of the operating system for desktops and laptops is mainly focused on performance improvements, security and bug fixes, instead of making changes perceptible naked eye. Taking into account the notes changes from previous versions of OS X betas, the update improves stability, compatibility and security of the Mac.
No obvious changes or bug fixes that have been found in the first three betas, but detail later if something comes up again in this fourth beta of OS X El Capitan.
Apple has also started testing macOS Sierra granting developers the first beta of the operating system and reportedly will be released in September.
Sierra macOS includes features such as the integration of Siri to execute commands for you and can find photos, videos, open applications, among other things. Another novelty is that macOS Sierra has the possibility to be unlocked by an Apple Watch, among many other features.
The batch update also affects iOS 9.3.3 and 9.2.2 TVOS available for both developers and for beta testers who have subscribed to Apple testing program.
