Kumiko vs macOS window tiling
Apple added window tiling in macOS Sequoia. For many people it is enough. On a big screen, its limits show quickly.
Updated
Short answer: Built-in tiling covers halves and quarters on any Mac for free. Kumiko adds thirds, sizes that suit ultrawides, whole-screen layouts, Resume and the AI command bar.

- fn⌃ + arrow shortcuts, plus arrangements for two or four windows
- Nothing to install
What Kumiko adds
- Arrow keys that know your screen. Hold ⌃⌥ and press ← or →. Press again to go from ½ to ⅔ to ⅓. On a 21:9 or 32:9 ultrawide the first press gives a third, and ↑ gives you the centre column.
- Six layouts for the whole screen. Focus centre, Halves, Thirds, Studio, Stack and Columns place every window at once with ⌃⌥1 to ⌃⌥6.
- Resume. Close the lid and Kumiko brings back every browser tab, the project folder in your editor and the folder each terminal was in. It works with 45 apps.
- The AI command bar. Press ⌥ Space and type "review PR 482 and reply to the team". Kumiko picks the windows, opens what's missing, brings the right tab forward and shows you the plan first.
- Meeting and Share-safe. Calls move under your camera with notes below; private apps blur when you share your screen.
Which one should you pick?
Pick macOS window tiling if
You use a laptop or a standard 16:9 monitor and halves are enough.
Pick Kumiko if
You have a wide or big screen where halves waste space and you want thirds, centre columns and whole layouts.
Kumiko is €30 once for 2 Macs, and the first 25 launch licences are €9. It works on macOS 14 or later.
Questions
What are the macOS window tiling shortcuts?
With the window you want selected: fn⌃← and fn⌃→ for left and right halves, fn⌃↑ and fn⌃↓ for top and bottom, fn⌃F to fill, fn⌃C to centre and fn⌃R to go back. Add ⇧ to arrange two windows side by side.
Can I use Kumiko and macOS tiling together?
Yes. They use different shortcuts (Kumiko uses ⌃⌥ with the arrows). If dragging to an edge feels doubled up, turn off "Tile by dragging windows to screen edges" in System Settings › Desktop & Dock.
Does macOS tiling do thirds?
No. Built-in tiling does halves and quarters only. Kumiko does thirds and two-thirds, and on an ultrawide the first press gives you a third.
