Mac Window Switcher and Manager Apps for Windows Users

For Alt+Tab-style switching on a Mac, install AltTab: it’s free and lists every window with a thumbnail, minimized ones included. For Windows-style snapping, use the tiling built into macOS 15 and later (Fn + Ctrl + ← or →), and add Rectangle if you want more layouts.

What Windows users miss on a Mac

Coming from Windows, you usually miss two different things, and they are solved by different kinds of apps. A window switcher replaces Alt+Tab: one shortcut that cycles through every open window. A window manager replaces Win + arrow snapping: putting a window on half or a quarter of the screen.

On a Mac, Cmd + Tab shows one icon per app, and Cmd + ` cycles through the windows of the front app. The full list of shortcut equivalents, and how the Windows key maps to Command on a Windows keyboard, is in Alt+Tab on Mac.

Window switchers: Alt+Tab style

A switcher gives you one list of windows instead of apps. I build one of the apps below, Command Reopen, so keep that in mind; the other details come from each app’s own website, checked in October 2026.

AltTab

AltTab is the closest thing to Windows’ Alt+Tab. It runs on Option + Tab by default and shows a thumbnail of every window, including minimized and hidden windows and windows on other Spaces; pick one and it comes to the front. It’s free and open source, with a paid Pro version that adds search, layouts and more shortcuts. It needs Accessibility permission, plus Screen Recording for the thumbnails, and runs on macOS 12 or later. A side-by-side comparison goes into the trade-offs.

Witch

Witch from Many Tricks is a long-running keyboard switcher that lists windows, and also browser tabs, instead of apps. You can act on a window straight from the list, for example press M to minimize it. It costs $14 with a free trial and supports macOS 10.13 and later, so it suits people who want a configurable list without thumbnails.

DockDoor

DockDoor is for people who miss the Windows taskbar more than Alt+Tab. Hover over an app in the Dock and its windows appear as previews; it also adds a window switcher on Option + Tab. It’s free and open source, needs Accessibility, plus Screen Recording for previews, and runs on macOS 13 or later. More in the DockDoor comparison.

Contexts

Contexts lets you jump to a window by typing part of its title after Control + Space, and adds a sidebar of windows. It costs $9.99 with a free trial and needs Accessibility. Its latest release, 3.9, came out in August 2022, so check that it still works on your macOS version before you buy. More in the Contexts comparison.

Command Reopen

Command Reopen takes the opposite approach: it keeps the Mac’s own Cmd + Tab and fixes the part that surprises Windows users most. When you switch to an app that has no visible window, it brings back the minimized window, or opens a new one if the app has none. You still switch apps, not individual windows, and there are no thumbnails. It needs no permissions, so it also works on company Macs that block Accessibility, and it’s on the Mac App Store for $9.99 one-time or $5.99/year after a 14-day free trial.

Window managers: Windows-style snapping

A window manager moves and resizes windows. Since macOS 15 Sequoia, the Mac does the basics on its own, so try the built-in tiling before installing anything.

Built-in tiling (macOS 15 and later)

Apple documents these ways to tile windows:

1. Drag a window to the left or right edge of the screen and release it when the highlighted area appears. Drag to a corner for a quarter. If snapping doesn’t start, hold Option while you drag.
2. Or hold the pointer over the window’s green button and choose a layout under Move & Resize.
3. Or use the keyboard: Fn + Ctrl + ← and Fn + Ctrl + → for left and right halves, Fn + Ctrl + F to fill the screen, Fn + Ctrl + C to center, and Fn + Ctrl + R to return to the previous size.

Apple lists all of them in window tiling keyboard shortcuts. What’s missing compared with dedicated apps is custom layouts such as thirds, and shortcuts you can change.

Rectangle

Rectangle is a free, open-source window manager with keyboard shortcuts and snap areas: halves, quarters, thirds, moving a window to the next display and more. You can install it from its website or with brew install --cask rectangle, and it runs on macOS 10.15 or later, so it also covers Macs too old for built-in tiling. It needs Accessibility permission. Rectangle Pro is a separate paid app built on it, with extras such as moving windows between Spaces, and a 10-day free trial.

Magnet

Magnet does the same job from the Mac App Store. Drag a window to an edge or corner, or use its keyboard shortcuts, both of which you can customize. It costs $4.99 and needs macOS 13 or later. Pick it over Rectangle if you’d rather buy from the App Store.

Which ones to install

Pick by what you miss most. One app from each group is plenty, and built-in tiling may be all you need:

• You want Alt+Tab exactly as on Windows: AltTab, if you can grant Accessibility and Screen Recording.
• You want Windows taskbar previews: DockDoor.
• You only want Cmd + Tab to stop leaving windows in the Dock: Command Reopen, with no permissions to grant.
• You want snapping: the built-in tiling first; Rectangle or Magnet if you need more layouts or your own shortcuts.

A switcher and a window manager don’t conflict, so you can run, say, AltTab and Rectangle side by side.
