Fix Guide: Window Tiling Not Working on macOS Sequoia

Symptom: You drag a window to the edge of the screen, but the new Sequoia window tiling (snapping) does not activate, or the green "hover" previews are missing.

Why this happens

Sequoia's native window tiling can conflict with 3rd party window managers (like Rectangle or Magnet). It can also be disabled by "Displays have separate Spaces" settings in Mission Control.

Recommended Troubleshooting Tool

Fix 1: Check System Settings

1. Go to System Settings > Desktop & Dock.
2. Scroll down to the Windows section.
3. Ensure "Drag windows to screen edges to tile" is toggled ON.
4. Ensure "Hold Option key while dragging to tile" is set to your preference.

Fix 2: Mission Control Reset

1. Go to System Settings > Desktop & Dock.
2. Find "Displays have separate Spaces".
3. Toggle it OFF and then ON again (requires logout). This often fixes the window snapping engine.

Recommended Tool: Rectangle

If Sequoia's built-in tiling feels too limited:

- Get Rectangle (or Rectangle Pro) for much more powerful keyboard shortcuts and snapping zones that go beyond what Apple currently offers in Sequoia.
