How do I split windows in half on a Mac?
Built into macOS
On macOS 15 (Sequoia) and later, dragging a window to an edge or corner of the screen tiles it. On earlier versions you can press and hold a window's green button for options like “Tile Window to Left of Screen”. Both need the mouse.
KittyKit window layout
Place the current window right away with a shortcut or a menu bar item.
- Left half, right half
- Fill the screen, center
- Move to the next monitor
You can change the shortcuts in Settings, and it warns you if one clashes with another action or a macOS shortcut (⌃ or ⌘ is required). It needs the Accessibility permission, and it tells you why when there is no window, the window can't be resized (such as full screen) or there is only one monitor. Window layout is a Pro feature with a 7-day free trial.
