what is the latest version of osx el capitan
OS X El Capitan OS X El Capitan (/ɛl kæpɪˈtɑːn/ el-KAP-ɪ-TAHN) (version 10.11) is the twelfth major release of OS X (now named macOS), Apple Inc.'s desktop and server operating system for Macintosh computers. It is the successor to OS X Yosemite and focuses mainly on performance, stability and security.[2] Following the Northern California landmark-based naming scheme introduced with OS X Mavericks, El Capitan was named after a rock formation in Yosemite National Park, signifying its goal to be a refined version of Yosemite. El Capitan is the final version to be released under the name OS X; its successor, Sierra, was announced as macOS Sierra. El Capitan received far superior reviews when compared to Yosemite.
