Apple has released a third beta OS X of El Capitan for developers and public beta program members.
The new build 15C40a focuses on fixing bugs and further improving various functionality: Wi-Fi, graphics, network, USB, Calendar, Notes, Photos and Spotlight.
Judging by the fact that the previous beta for developers and testers came out only a week ago, the new version of the operating system is close to completion. 3 weeks have passed since the last update OS X (10.11.1), in which 150 new emojis were added.
You can upgrade from the previous beta OS X 10.11.2 to this one in the Updates tab on Mac App Store. You can also download the update through the Developer Center or on the website Apple after registering for the testing program.
Along with this, iOS 9.2 beta 3 and tvOS 9.1 beta 2 were also released for public testing.
