Apple today released OS X 10.11.3 to the public, marking the launch of the third update to the El Capitan operating system that was first released on September 30. In testing since December 16, OS X 10.11.3 follows the December launch of OS X 10.11.2. Prior to release, Apple seeded three betas of OS X 10.11.3 to developers and public beta testers.

The OS X 10.11.3 update can be downloaded through the Software Update mechanism in the Mac App Store. It is available to all OS X El Capitan users.



During the beta testing period, no significant outward-facing changes were discovered in OS X 10.11.3, with the update instead aiming to improve performance and fix bugs discovered since the launch of OS X 10.11.2. According to Apple's release notes, OS X 10.11.3 includes unspecified bug fixes and security updates.

The OS X El Capitan 10.11.3 update improves the stability, compatibility, and security of your Mac. This update contains bug fixes and security updates.

OS X 10.11.3 will be followed by OS X 10.11.4, which is already in testing and has been provided to developers. Like OS X 10.11.3, OS X 10.11.4 appears to be focused on fixing bugs and improving performance rather than introducing new features. OS X 10.11.4 will likely see a spring debut alongside iOS 9.3.
