  • Two open apps or windows
  • Recent macOS version
  • Trackpad or mouse

Safety Precautions

  • Save work before rearranging important windows.

    Open two windows

    Launch the apps or documents you want side by side.

  2. Step 2

    Hover over green button

    Move the pointer over the green full-screen button on one window.

    Select Tile Window to Left of Screen or Right of Screen.

  4. Step 4

    Pick second window

    Click the window you want on the other side.

  5. Step 5

    Switch spaces if needed

    Use Mission Control to find the Split View space.

  7. Step 7

    Exit split screen

    Move to the top of the screen and click the green button again.

Practical Example

Example: You put a browser on the left and Notes on the right so you can research and write without switching windows.
