OS X El Capitan (/ɛl ˌkæpɪˈtɑːn/ el KAP-i-TAHN) (version 10.11) is the twelfth major release of macOS (named OS X at the time of El Capitan's release), Apple Inc.'s desktop and server operating system for Macintosh. It focuses mainly on performance, stability, and security.^[3] Following the California location-based naming scheme introduced with OS X Mavericks, El Capitan was named after a rock formation in Yosemite National Park. El Capitan is the final version to be released under the name OS X. OS X El Capitan received far better reviews than Yosemite.

The first beta of OS X El Capitan was released to developers shortly following the WWDC keynote on June 8, 2015.^[4] The first public beta was made available on July 9, 2015.^[5] There were multiple betas released after the keynote. OS X El Capitan was released to end users on September 30, 2015, as a free upgrade through the Mac App Store.^[6]

OS X El Capitan is the final version of OS X to support Aluminum Macs and Xserve, as its successor, macOS Sierra drops support for the mid 2007 and final models.
