Split View lets you have two apps running side-by-side on one Mac screen without having to resize either window. This saves you from switching between apps and losing your place if you’re working in two different programs.

Here’s how to enable and turn off Split View.

1. Open two apps and place them on opposite sides of the screen.

2. In the top left corner of one app’s window, hover over, or click, the green bubble to open a dropdown menu.

3. Select either Tile Window to the Left of the Screen or Tile Window to the Right of the Screen. That app will fill that side of the screen.

4. Click the other app on the opposite side of the screen for the app to fill the remainder of the screen.

To exit Split View, click the green bubble again or press Esc on your keyboard. This only exits one app from Split View -- the other app will now be in full-screen mode on its own Desktop.
