Enter Split View
Split View requires OS X El Capitan or later, and the steps differ slightly based on which macOS you're using. If these steps don't work, choose Apple menu > System Preferences, click Mission Control, and make sure that “Displays have separate Spaces” is selected.
- Hover your pointer over the full-screen button in the upper-left corner of a window. Or click and hold the button.
- Choose ”Tile Window to Left of Screen” or ”Tile Window to Right of Screen” from the menu. The window then fills that side of the screen.
- Click a window on the other side of the screen to begin using both windows side by side.
Other macOS versions
- Click and hold the full-screen button in the upper-left corner of a window.
- As you hold the button, the window shrinks and you can drag it to the left or right side of the screen.
- Release the button, then click a window on the other side of the screen to begin using both windows side by side.
