OS X 10.11 El Capitan

Released in September 2015, El Capitan was pitched as a performance and stability update to Yosemite. As such, many of the features were behind the scenes, such as System Integrity Protection, better PDF rendering and support for Metal. Split screen apps were possible for the first time, and were managed within Mission Control. Notes received a major overhaul, matching most of the features found in the iOS 9 version of the app.

OS X 10.11 changed the system font again, this time to Apple’s own San Francisco. It was also the first release to have Dashboard disabled by default on new installations.
