el capitan - Computer Definition
Version 10.11 of the Mac OS X operating system, named after a rock formation in Yosemite National Park. With the first beta released in June 2015, El Capitan includes faster performance and a raft of enhancements, plus new features in Notes, Mail, Safari, Maps and Mission Control. On startup, the cursor starts out large for instant recognition on huge screens, and two selected apps can snap side-by-side to fill the screen. Spotlight is more context sensitive and accepts natural language. Enhancements to Chinese and Japanese input, and Arabic and Hebrew dictation are added. The Metal programming interface (API), introduced in iOS 8, is added for faster graphics (developers can get closer to the hardware). See Mac OS X and Yosemite.
