DockThumbTile Mac windows from the keyboard. No more dragging edges.
Window tiling means snapping windows into halves, thirds or a grid so they share the screen without overlapping. On a big display or a laptop with two apps side by side, it saves a lot of small mouse moves.
What macOS does by default
Since macOS 15 Sequoia, you can drag a window to a screen edge to snap it, or use the Window menu › Move & Resize. That covers halves and quarters. There are no thirds, no layouts for several windows at once, and no way to sort every window of a type into a grid.
How it works in DockThumb
- All shortcuts sit on ⌃ ⌥ and follow your keyboard layout, AZERTY included.
- Arrows for halves and full screen, 1, 2, 3 for thirds, U, I, J, K for corners.
- Whole layouts at once: two or three columns, main window + stack, or a grid.
- ⌃⌥A sorts every open window into a grid by type. ⌃⌥Z undoes the last layout.

Questions
Does macOS have built-in window tiling?
Yes, since macOS 15 Sequoia: drag a window to an edge, or use Window › Move & Resize. It handles halves and quarters. A tiling app adds thirds, multi-window layouts and faster shortcuts.
What is the keyboard shortcut to split the screen on Mac?
With DockThumb, ⌃⌥← and ⌃⌥→ put the active window on the left or right half. On macOS 15 and later without an app, the Window menu lists the native tiling commands and their shortcuts.
