Mac OS X El Capitan revealed at WWDC keynote

Apple shows off the new features of its newest notebook operating system.

Every year in June, Apple kicks off its Worldwide Developer's Conference week with a keynote outlining new operating system features for devs. First up was their announcement for the new OS for Mac, called OS X El Capitan. The features focus on heightening both the experience and performance for users. First, Mission Control has been refreshed for better window and app management, and a feature called Split View has been added.

Split View enables an application to fill half of the screen so the user can focus on two at the same time. Spotlight has also been enhanced to search more comprehensively and will include sports, weather, stocks, and other information. Searching is also easier, and Spotlight understands searches in natural language. Safari has also been refreshed for El Capitan. Tabs can now be "pinned" to the tab bar for convenience, and AirPlay will have the option to stream video from the browser to a TV. A few other features were unveiled, but the largest changes come to performance.

Apple has made a lot of architectural changes to El Capitan. App launch is now 1.4x faster, app switching is 2x faster, and opening a PDF is up to 4x faster. They have added Metal to Macs too, and it has allowed them to speed graphics rendering by up to 50%, and is 40% more efficient. OS X El Capitan will bring some great new UI features and a lot of under-the-hood improvements when it releases as a free update in the Fall.
