Building on last year's Yosemite update, Apple presents OS X El Capitan, their latest update to the Mac OS X operating system. The company calls their newest update an "Experience and Performance" upgrade with this year's OS X perfecting the fit and finish, tightening up such as app speed and switching and a variety of new UI features.
UI updates include improvements to Mission Control, split view in full screen mode, and a more robust Spotlight with additions like sports scores and weather. You'll also see graphics performance tweaks across the board with faster rendering performance on the desktop and in your favorite games. El Capitan will be available for Public Beta next month and will be officially available this Fall.
