macOS Sequoia (15) and later can tile windows from the keyboard. This guide lists the keys, how to send a window to another display, and where the built-in tools stop.
Tile one window
Click the window first, then press:
| Shortcut | What it does |
|---|---|
| fn ⌃ ← / → | Left or right half of the screen |
| fn ⌃ ↑ / ↓ | Top or bottom half |
| fn ⌃ F | Fill the screen (not full screen) |
| fn ⌃ C | Centre the window |
| fn ⌃ R | Return to the size it had before tiling |
Add ⇧ to an arrow shortcut to arrange two windows at once: the active window on one side and the previous one on the other.
Quarters have no shortcut. Use Window → Move & Resize in the menu bar; holding ⌥ while the menu is open shows more arrangements. On newer Mac keyboards the fn key is the Globe key.
Tile with the mouse
Drag a window to the edge of the screen until an outline appears, then let go. Drag to a corner for a quarter. Holding ⌥ while dragging shows the outline straight away.
You can turn these off, or the margins between tiled windows, in System Settings → Desktop & Dock.
Move a window to another display
With more than one display connected, the Window menu (under Move & Resize in Sequoia and later) offers Move to followed by the other display’s name. You can also drag the window across.
Before Sequoia
macOS Sonoma and earlier have no tiling keys. Hovering over the green button in a window’s corner offers Tile Window to Left/Right of Screen, which puts two apps side by side in full screen on a new desktop.
Where the built-in keys stop
The shortcuts arrange the window you are in, one or two at a time. They don’t:
- arrange every app across several displays in one step,
- remember an arrangement or put it back after a monitor reconnects,
- open the apps you need or hide the ones you don’t.
That is what Flincth Workspace Manager does. A setup places each app’s windows across all your screens and switches its clipboard history; give it a shortcut such as ⇧⌘D and one press arranges the whole desk. It works alongside the tiling keys rather than replacing them. Start with How to Create Your First Setup, or see how to make your Mac remember window positions.
