Mac Window Tiling Shortcuts Not Working? What's Actually Going On (and How to Fix It)

macOS Sequoia's window tiling keyboard shortcuts — the ones that appear when you hover over the green traffic light button — stop working for a handful of specific, fixable reasons: Accessibility permissions being denied, conflicts with other apps grabbing the same key combos, or Sequoia's tiling feature simply being toggled off in System Settings. None of them are obvious, and Apple doesn't tell you which one is the culprit.

Why macOS Sequoia window tiling has shortcuts at all

Sequoia (macOS 15) introduced native window tiling as a proper feature for the first time. You can drag a window to the edge of the screen to snap it, or hover over the green button to get a layout picker. What most people don't know is that Sequoia also added keyboard-driven tiling — but the shortcuts are buried and easy to accidentally disable or conflict with.

The shortcuts live under System Settings → Desktop & Dock → Windows and control things like tiling left half, right half, and filling the screen. They're not printed on any obvious menu, which is why so many people don't even know they exist until they stop working.

The most common reason: tiling is switched off entirely

Before debugging shortcuts, confirm the feature is actually enabled.

1. Open System Settings → Desktop & Dock
2. Scroll to the Windows section
3. Check that "Tile by dragging windows to screen edges" is on
4. Also check "Hold Option key while dragging to tile" — this is separate and off by default

If tiling is off, no shortcut will do anything. This toggle has been known to reset after macOS point-release updates (15.3 and 15.4 both caused reports of this).

Shortcut conflicts with other apps

This is the most overlooked cause. If you have any of these installed, they almost certainly claim the same key combos Sequoia wants to use:

• Rectangle — uses ⌃⌥← and ⌃⌥→ by default, which clash with Sequoia's half-screen shortcuts
• Magnet — same story
• BetterSnapTool — customisable but often conflicts out of the box
• Alfred, Raycast — can grab modifier-heavy shortcuts if you've set custom triggers
• Any app with a global hotkey set to ⌃⌥↑↓←→

The test: open System Settings → Keyboard → Keyboard Shortcuts → App Shortcuts and look for anything using the same modifiers. Also check the preferences of any window manager or launcher you have installed.

If you find a conflict, either reassign the conflicting shortcut or disable it. Rectangle in particular has a setting to disable all shortcuts in its preferences — you can keep it installed without it stealing keys.

Sequoia's tiling shortcuts aren't actually customisable

Here's a genuinely frustrating limitation: unlike most macOS shortcuts, Sequoia's built-in tiling shortcuts can't be remapped through System Settings → Keyboard. Apple hardcoded the modifier pattern. If another app claims those keys, you either move the other app's shortcut or you're stuck.

This is one of the reasons people end up switching to dedicated window managers — they give you explicit control over what keys do what, without fighting over system-level shortcuts.

Missing tiling icons on the green button

If the layout picker doesn't appear when you hover the green traffic-light button:

• Make sure you're hovering (not clicking) — it requires a deliberate pause
• Check you're not in full-screen mode for any other app (this can suppress the picker in adjacent windows)
• Try holding the Option (⌥) key while hovering — on some Sequoia versions this surfaces additional layout options
• Restart the WindowManager process: open Terminal and run killall WindowManager. It restarts automatically. This fixes phantom states where tiling stops responding without any clear reason.

When dragging to the edge doesn't snap

Drag-to-snap can stop working independently of keyboard shortcuts. If dragging a window to the edge of the screen does nothing:

1. Confirm "Tile by dragging windows to screen edges" is on (same setting as above)
2. Check you're dragging by the title bar, not a toolbar or sidebar
3. Some apps (notably Electron apps like Slack) resist snapping because they override their own window chrome — this is a per-app issue, not a system setting
4. Log out and back in — Sequoia's window compositing layer occasionally needs a reset

When it keeps breaking after updates

If your tiling shortcuts work fine, then a Sequoia update ships and they stop again, you're not imagining it. Apple's point releases have reset window management preferences at least twice since Sequoia launched. The fix each time is the same: go back to System Settings → Desktop & Dock → Windows and re-enable the settings.

This is genuinely annoying, and it's one of the concrete reasons people look for alternatives.

If you've fixed it but still find Sequoia tiling too limited

Sequoia's native tiling covers the basics — left half, right half, quarters, full screen. What it can't do:

• Save a named layout and restore it with one shortcut
• Automatically reapply layouts when you plug in or unplug a monitor
• Handle multi-monitor setups gracefully
• Schedule layouts by time of day

If you've sorted the shortcut issues and still find yourself manually repositioning windows every morning, or losing your layout every time you undock your MacBook, that's where Layoutish picks up. It stores named layouts (all windows, all monitors), restores them with a single keystroke, and detects monitor changes automatically. The price goes up to $9.99 on 1 September 2026 — it's $6.99 until then.

Common questions

Why do my Mac window tiling shortcuts work sometimes but not others?

Intermittent failures usually point to a shortcut conflict — another app is grabbing the key combo when it's in focus. Quit your other window manager or launcher apps one at a time to identify the culprit, then reassign that app's conflicting shortcut.

Does macOS Sequoia window tiling work on all Macs?

Native window tiling requires macOS Sequoia (15.0 or later). The keyboard-driven layout picker requires a Mac with a mouse or trackpad that supports hover — it won't appear on Magic Keyboard input alone. All Apple Silicon Macs and Intel Macs running Sequoia are supported.

Can I use Rectangle and Sequoia tiling at the same time?

Technically yes, but practically you'll hit shortcut conflicts immediately. The cleanest approach is to pick one: either disable all Rectangle shortcuts (in Rectangle → Preferences → uncheck shortcuts) and rely on Sequoia's native tiling, or disable Sequoia's tiling in System Settings and use Rectangle for everything. Running both with shortcuts active leads to unpredictable behaviour.
