OS X : How to use Split View in OS X El Capitan
Here’s how to use OS X El Capitan’s Split View feature
Open the two apps you want to use in OS X El Capitan’s split view. Don’t minimize any of the apps. Click and hold the expand (green) button on any app’s window, and it will be snapped to the left side of your screen. Now right side will show small thumbnails of the other running apps that support split view. Select the one you want and you’ll be in Split view. Enjoy!
