OS X Yosemite (/joʊˈsɛmɪtiː/ yoh-SEM-it-ee) (version 10.10) is the eleventh major release of OS X (now named macOS), Apple Inc.'s desktop and server operating system for Macintosh computers.
OS X Yosemite was announced and released to developers on June 2, 2014 at WWDC 2014 and released to public beta testers on July 24, 2014. Yosemite was released to consumers on October 16, 2014. Following the Northern California landmark-based naming scheme introduced with OS X Mavericks, Yosemite is named after the national park.
