OS X El Capitan (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. 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 did Yosemite.
