OS X El Capitan
OS X El Capitan is a new version of OS X that refines the Mac experience and improves system performance. Building on last year’s landmark release of OS X Yosemite, El Capitan introduces enhancements to window management, built-in apps and Spotlight search, and makes everyday activities — from launching apps to accessing email — faster and more responsive. Metal, Apple’s breakthrough graphics technology, is integrated into El Capitan, delivering system-wide performance gains and enabling games and pro apps to tap into the full power of Mac graphics processors.
