Short answer
You can manage Mac windows with macOS's own tiling, a free tiling utility such as Rectangle, a paid tiler such as Magnet, a switcher such as AltTab, or an all-in-one like Casement. They differ in layouts offered, whether they switch windows, and permissions needed. Most need Accessibility permission.
Categories
| Approach | Typically gives you | Cost model |
|---|---|---|
| macOS built-in | Tile to halves and quarters; Command-Tab for apps; Mission Control | Included |
| Free tiling utilities (for example Rectangle) | Keyboard and drag snapping to halves, thirds and more | Free, open source |
| Paid tiling utilities (for example Magnet) | Drag and keyboard snapping | One-time or subscription, depending on the app |
| Window switchers (for example AltTab) | Alt-Tab style list of windows | Free, open source |
| Casement | Layout picker, window switcher, Dock window lists, hover to focus, drop shelf, display control, Chrome profile Dock icons | Free core; $9 once for Chrome profile Dock icons |
Questions that separate them
- Do you want a layout picker you can see, or keyboard shortcuts only?
- Do you need to switch between windows, not just apps?
- Do you use several Chrome profiles?
- Do you prefer one app or several small ones?
Things to consider
- Check each tool's current feature list and price on its own site; they change.
- Two tools that both react to dragging to an edge can conflict. Turn off the system option if you use one.
- Permissions: most window tools need Accessibility; some also need Screen Recording for previews.
Questions people ask
Can I use more than one together?
Yes, as long as only one handles each gesture.
