Snap windowson a Mac,no app needed

For years, putting two windows side by side on a Mac meant installing Rectangle or Magnet. Since macOS 15 Sequoia, window tiling is built in. Here is everything it can do, and the keyboard shortcuts that make it fast.

The shortcuts

The tiling shortcuts use the fn (Globe ๐ŸŒ) key together with Control:

  • fn โŒƒ โ† / fn โŒƒ โ†’: left or right half of the screen
  • fn โŒƒ โ†‘ / fn โŒƒ โ†“: top or bottom half
  • fn โŒƒ F: fill the screen without going full screen (the menu bar and Dock stay visible)
  • fn โŒƒ C: center the window
  • fn โŒƒ R: return to the size and position it had before

You'll find all of them, and more layouts such as quarters, under Window โ†’ Move & Resize in any app. The menu shows the current shortcut next to each item.

Drag to tile

  • Drag a window to the left or right edge of the screen. A preview appears and the window fills that half when you let go.
  • Drag to a corner to fill a quarter.
  • Drag to the menu bar to fill the whole screen.
  • Hold โŒฅ Option while dragging to see the tiling preview straight away, anywhere on the screen.

You can also hover over the green button in a window's top-left corner to pick a layout with the mouse.

Settings worth changing

Open System Settings โ†’ Desktop & Dock and scroll to Windows:

  • Drag windows to screen edges to tile: turn this off if windows snap when you don't want them to. The keyboard shortcuts keep working.
  • Hold โŒฅ key while dragging windows to tile: tiling then only happens when you ask for it.
  • Tiled windows have margins: turn it off for edge-to-edge windows with no gaps.

Moving a window to your other monitor

With two or more displays, the Window menu also has Move to [display name]. To make it a shortcut, go to System Settings โ†’ Keyboard โ†’ Keyboard Shortcuts โ†’ App Shortcuts, add a shortcut for All Applications, and type the menu title exactly as it appears, for example Move to LG HDR 4K.

Tiling shortcuts work on whichever screen the window is on. Snap it to the left half of the monitor, then to the right half of the laptop, all from the keyboard.

On macOS 14 or earlier

Hover over the green button and choose Tile Window to Left/Right of Screen, which opens both windows in full-screen Split View. For real desktop tiling with shortcuts, the free, open-source Rectangle is the classic choice; its default is โŒƒ โŒฅ โ† / โ†’ for halves.

One more thing for multi-monitor setups

Tiling solves where windows go. It doesn't solve where your typing goes: on a Mac, keyboard focus stays with the window you last clicked, even after you turn to the other screen. I made KeyFollow for that. It notices which screen you look at, using the Mac's camera on-device, and moves focus there so you can just start typing.
