Apple’s Mac OS X El Capitan is now available in public beta. It’s the first public beta of OS X El Capitan, and since it’s beta version, do expect some bugs to encounter.
OS X El Capitan 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.
In order to access the public beta of OS X El Capitan (or future beta programs), you must enroll to Apple Beta Software Program.
