A tiny menu bar app that makes Cmd+Tab switch between windows the way Alt+Tab works on Windows. Cmd+` keeps working as before. It also adds an on-demand Dock on Option+Tab, and makes a window's green button maximize instead of going full screen. Each of these can be turned off in the menu.
| Key | Action |
|---|---|
| Tab / Shift+Tab | Next / previous window |
| ← → ↑ ↓ | Move the selection around the grid (grouped: ↓ into the app's window previews, ← → between them, ↑ back) |
| F | Find: type part of an app's name or a window's title to show only the windows that match, then Return to switch |
| Release Cmd, or press Return | Switch to the selected window |
| W | Close the selected window |
| Q | Quit the selected window's app |
| M | Minimize / restore the selected window |
| H | Hide / show the selected window's app |
| G | Group / ungroup windows by app (remembered for the next Cmd+Tab) |
| R | Switch between the grid and a big ring (the Dock follows), with R Toggles Ring Layout on in the menu (it's off by default, and R beeps) |
| . | Switch between app icons and window thumbnails (the same choice as in the menu, so it sticks for the next Cmd+Tab; grouped too) |
| N | Open a new window of the selected window's app, and switch to it |
| T | The tiling menu for the selected window (← ↑ ↓ → and Return to pick, Esc to close) |
| X | Exchange: close the switcher (without switching) and open the Dock instead |
| ? | Show / hide a bubble listing these keys and mouse actions |
| Esc | Cancel |
| Mouse hover / click | Select / switch (in icon view, hovering also shows the window title if the bubble doesn't already) |
| Right-click | The tiling menu for that window |
A quick Cmd+Tab tap jumps straight to the previous window without showing the switcher. Windows are listed in most-recently-used order, with minimized windows last.
W, Q, M and H act on the selected window (or, grouped, the highlighted preview's window, or the app's most recent one) and keep the switcher open, so you can tidy up several windows in one go. Holding one of these keys acts only once. N opens a new window through the app's own New Window menu item (or one like New Finder Window), found by name rather than by shortcut, because Cmd+N and Cmd+Shift+N mean different things in different apps (in Finder, Cmd+Shift+N makes a new folder). An app without such an item beeps. Finder can't be quit with Q. Restoring a minimized window of a hidden app with M also unhides that app, the same as clicking the window's thumbnail in the Dock.
X swaps the switcher for the Dock and back. After X from the switcher, you're still holding Cmd: until you let go of it, keys typed with it go to the Dock (letting go doesn't close it). After X from the Dock, the switcher stays up until you press Return, Esc or click, since you aren't holding Cmd; press and hold Cmd to get the usual "let go to switch" back. X beeps if the other one is turned off in the menu.
Press F (still holding Cmd) and type part of an app's name or a window's title to find a window. In the Dock, F finds an app, a folder or the Trash by name.
- Only the tiles that match stay, in their usual order and at their usual size, and the best match is selected. A name or title that starts with what you typed comes first, then one with a word that starts with it, then one that has it anywhere. Ties go to the more recently used window (in the Dock, to the item further left).
- Case and accents don't matter. Each word you type can match anywhere, so "chr git" finds a Chrome window titled GitHub. Grouped, an app shows if its name or any of its windows' titles match, with only the matching windows in its previews.
- A key that would leave nothing matching beeps and isn't added, so a typo after a name is already unique does no harm. Backspace deletes. Tab, the arrow keys and the mouse work as usual among the matches.
- Return switches to the selected window (in the Dock, opens the selected item). While the search is up, letting go of Cmd doesn't switch. You can let go and type comfortably, then press Return. Keys typed while you still hold the Cmd you pressed F with go into the search too.
- Esc stops typing but keeps the search: it dims (read-only), the matches stay, and every key works on them as usual, so you can close several windows of one app with W, hide one with H, and so on. Press F to edit the search again. If none of the matches are left, the search goes and every window comes back.
- Clear the search with the ✕ at its end, with Delete while it's read-only, or with Cmd+Delete while typing. Every tile comes back, the selection stays, and the search stays up, empty.
- Esc on an empty search puts it away, with the selected tile still selected. On a read-only search with something in it, Esc cancels the switcher (or closes the Dock), as it does without a search. Without Cmd held, the switcher stays up until Return, Esc or a click once the search is gone, as after X.
- While typing, the keys that act on the selection also work with Cmd, as in any search field: let go of Cmd, then press Cmd+W, Cmd+Q, Cmd+M, Cmd+H and so on.
- Typing follows your keyboard layout, without Option's special characters. Input methods that compose characters, such as Japanese or Chinese, can't be used. While Cmd is held, macOS's own shortcuts (such as Cmd+Space for Spotlight) may still take the key, so type spaces after letting go of Cmd.
Press G (still holding Cmd) to show one icon per app instead of one per window, like the native switcher. The selected app's windows hang below its icon as previews, the same as in the Dock: press ↓ to move into them, ← → to pick one, ↑ to go back. Letting go of Cmd switches to the highlighted preview's window, or else to the app's most recent window. Press G again to go back to one icon per window. In thumbnail view, each app's tile shows a thumbnail of its most recent window instead of its icon, with all its windows below as usual (none for an app with only one window, since its tile already shows it); press . to switch between the two, grouped or not. Grouping is remembered: the next Cmd+Tab opens grouped too, until you press G again. Grouped, a quick Cmd+Tab goes to the previous app, like the native switcher.
First turn on R Toggles Ring Layout in the menu; it's off by default, and until then R just beeps. Then press R in the switcher or the Dock to lay the tiles out around a ring, the way WindowRing does, and press it again to go back to the grid (or the Dock's row). The ring is one setting for both, and it's remembered, so X swaps the window ring for the Dock ring and back, and the next Cmd+Tab or Option+Tab opens as a ring too. Turning R Toggles Ring Layout off puts both back to the grid and row.
- Tiles start at 12 o'clock and go clockwise in the usual order; Tab, → and ← go around the ring.
- The selected tile's wedge is highlighted, and its name (and window title) shows on a small card in the ring's see-through middle, where the ? help also appears.
- Point anywhere on the ring to select the tile in that direction, like a pie menu; click to switch.
- Window previews (grouped, the Dock's previews, Show Window Preview) are cards in an arc just outside the ring, centered on the selected tile and going clockwise; ↓ moves into them, ← → along the arc, and ↑ back.
- Icons and thumbnails (.), grouping (G) and every other key work the same as in the grid.
Right-click a window's tile (or, grouped, an app's icon or a window preview), or press T, for a menu like the one under a window's green button (the Dock's window previews have it too):
- Fill, Center. Like the green button, Fill toggles: while CmdTab has the window filled, the item reads Restore Size and puts it back
- Move & Resize: Left, Right, Top, Bottom; Top Left, Top Right, Bottom Left, Bottom Right; and arrangements that also place the next most recent windows: Left & Right, Right & Left, Top & Bottom, Bottom & Top, Quarters
- Return to Previous Size, after CmdTab has moved the window (shown as Restore Size above while it's filled)
- Enter / Exit Full Screen
- Move to another display, when you have more than one
Choosing one lays out the window on its display (minus the menu bar and Dock), closes the switcher and switches to it. While the menu is open, letting go of Cmd doesn't switch; closing the menu without a choice then switches, as letting go would have. CmdTab does these layouts itself; macOS's own Full Screen Tile (side-by-side full screen) isn't available to other apps.
- App icons (default): one large app icon per window, styled like the native macOS switcher. The selected icon gets a darker rounded square that hugs it, and its app name floats in a bubble above it, like the Dock's. When an app has more than one window listed, the bubble shows the window's title instead, so you can tell them apart. Otherwise, rest the pointer on an icon to see that window's title in a tooltip. With Show Window Preview on, a snapshot of the selected window also hangs below its icon; click it to switch to that window.
- Window thumbnails: a live snapshot of each window, with the app icon and window title above it. The selected tile gets the same darker rounded background as in icon view.
Choose between them in the menu, or press . while the switcher is up. Thumbnails and window previews need Screen Recording permission (System Settings → Privacy & Security → Screen & System Audio Recording), and CmdTab must be relaunched after you grant it. Until then, they show the app icon. Minimized windows, windows of hidden apps and windows on other desktops can't be captured live, so they show their last snapshot, or the app icon if CmdTab hasn't captured them yet.
On macOS 26 and later, CmdTab's panels use the same Liquid Glass material as the native switcher, with a thin border in the opposite tone so they stand out against a background of the same tone. The window switcher is tinted with your Accent color (System Settings → Appearance), in a shade that suits Light and Dark, so it can't be mistaken for the neutral Dock. Choose Graphite for a gray switcher. Earlier versions get a blurred, tinted panel instead. Either way they follow the Appearance setting.
A small yellow badge marks windows you can't currently see:
| Badge | Meaning |
|---|---|
| ● dot | The window is minimized (yellow, like the minimize button in a window's title bar) |
| ◯ ring | The window's app is hidden |
| ◉ ring around the dot | Both |
Normal windows have no badge. In icon view the badge sits on the icon's bottom-right corner; in thumbnail view it's at the right end of the title row.
A plain click on a window's green button maximizes the window to fill the screen (minus the menu bar and Dock) instead of taking it full screen. Click it again to put the window back where it was. Double-clicking a window's title bar does the same, instead of the system's Fill, which leaves a margin around the window. If you move or resize a maximized window, the next click maximizes it again rather than restoring.
Option-click the green button to go full screen, which is what a plain click does in standard macOS. Only clicks that land on the green button are affected, and hovering still shows the button's tiling menu. Turn this off in the menu to get the standard behavior back.
Press Option+Tab to bring up a Dock where you're working (per the Show On setting), laid out like the real one: Finder, your pinned apps (without any spacer gaps you added), the recent apps section (if it's on in Dock settings), running apps that aren't pinned, then a divider, your Dock folders (such as Downloads), and the Trash. Running apps have a dot under the icon, hidden apps get the ◯ badge, and the selected item's name floats above it. It's handy with several displays, or with the real Dock hidden.
This doesn't replace the system Dock: that stays where it is, and CmdTab's Dock is a second, temporary one that appears only while you want it. The two don't interfere. CmdTab reads your Dock's pinned apps, folders and Trash but never changes them, and opening an app from either one does the same thing. The usable area CmdTab uses for tiling and the green button leaves room for the system Dock, unless it's hidden.
To get a Dock that only shows up on demand, turn on auto-hide for the system Dock: System Settings → Desktop & Dock → Automatically hide and show the Dock (or press Option+Cmd+D). The system Dock then slides away until you move the pointer to its edge, and Option+Tab gives you CmdTab's Dock wherever you are, on whichever display you choose with Show On. Without auto-hide, both are simply available: use the system Dock by pointer and Option+Tab by keyboard.
Unlike Cmd+Tab, it stays up after you let go of Option, until you pick something, press Esc or Option+Tab again, or click outside it.
With Show Window Previews on (it's off by default), previews of the selected running app's windows hang below its icon, and they follow the selection. Click a preview, or press ↓ and then Return, to bring that window forward. The previews follow the Include Minimized Windows, Include Windows of Hidden Apps and Include Windows from All Desktops settings. Live snapshots need Screen Recording permission (see Views); without it, previews show the app icon and window title. Minimized windows and windows on other desktops show their last snapshot, or the app icon.
| Key | Action |
|---|---|
| Tab / Shift+Tab | Next / previous item |
| ← → | Next / previous item, or window preview while in the previews |
| ↓ / ↑ | Into the selected app's window previews / back to the icons (with previews on); between rows if the Dock wraps into a grid |
| F | Find: type part of an item's name to show only the items that match, then Return to open |
| Return, or click | Open the item, like clicking it in the Dock, or bring the highlighted preview's window forward |
| W | Close the highlighted preview's window |
| Q | Quit the selected app |
| M | Minimize / restore the window: the highlighted preview's, or else the app's most recent one |
| H | Hide / show the selected app |
| N | Open a new window of the selected app (an app that isn't running, or has no windows, just opens, as when clicked) |
| T | The tiling menu for the same window as M |
| G | Beeps: the Dock is already one icon per app (G groups in the switcher) |
| R | Switch between the row and a big ring (the switcher follows), with R Toggles Ring Layout on in the menu (it's off by default, and R beeps) |
| . | Beeps: the Dock always shows icons (. switches the switcher's view) |
| X | Exchange: close the Dock and open the Cmd+Tab window switcher instead |
| ? | Show / hide a bubble listing these keys and mouse actions |
| Esc, Option+Tab, or click outside | Close (with a search up, Esc stops typing, or puts away an empty search, first) |
| Any other key | Close, and the key goes to the app you're in (with a search up, it types, or beeps while the search is read-only) |
Opening an app activates it (launching it if needed), the same as a Dock click. Folders open in Finder.
Right-click a tile for its menu:
- Running app: its windows (choose one to bring it forward; ◆ marks minimized ones), Show in Finder, Hide/Show, Quit. Hold Option for Force Quit.
- Other apps and folders: Open, Show in Finder.
- Trash: Open, Empty Trash.
- Window preview (with Show Window Previews on): the tiling menu for that window. Choosing a layout applies it, closes the Dock and brings the window forward; closing the menu without a choice leaves the Dock open.
The menus never change your real Dock (no Keep in Dock / Remove from Dock). Items an app adds to its own Dock menu, such as a browser's New Window, aren't available to other apps, so they're not shown. The Dock follows the same Show On choice as the switcher.
The menu bar icon has these options:
- Cmd+Tab Shows Windows: turn the window switcher on or off. While it's off, the system Cmd+Tab works as usual. Its options are indented under it:
- Include Minimized Windows / Include Windows of Hidden Apps: show or skip those windows.
- Include Windows from All Desktops: also list windows on other Spaces (desktops), including full-screen ones. Picking one switches to its desktop. Off by default.
- Show App Icons / Show Window Thumbnails: choose the view.
- Show Window Preview (icon view, off by default): a snapshot of the selected window hangs below its icon, like the Dock's window previews. Click it to switch to that window. Not used while grouped, where the selected app's windows hang there instead.
- Group Windows by App: one tile per app, with the selected app's windows in a strip below (see Grouping). Pressing G in the switcher changes the same setting. Off by default.
- Option+Tab Shows Dock: turn the Dock on or off. It works independently of Cmd+Tab Shows Windows.
- Show Window Previews: preview the selected app's windows under its icon in the Dock. Off by default.
- Show On: where the switcher and the Dock appear. All Displays (the default) shows them on every display; arrow keys follow the grid on the pointer's display. Display with Pointer or Display with Active Window (the display showing most of the frontmost window) shows them on just one.
- Appearance: System, Light or Dark, for CmdTab's panels (the switcher, the Dock, previews and name bubbles) only.
- R Toggles Ring Layout: lets R switch the switcher and the Dock between their grid (or row) and a ring. Off by default: R then beeps, and they're never shown as a ring.
- Green Button Toggles Maximize Instead of Full Screen: see Green button. On by default.
- Keyboard Shortcuts…: both lists of keys and mouse actions, side by side in a window. The switcher and the Dock also show their list (the same one ? shows) the first time each appears.
- Launch at Login
- Accessibility Permission: shows whether it's granted, and opens System Settings if it isn't.
- Quit CmdTab
CmdTab runs on macOS 14 or later, on Apple silicon and Intel Macs.
-
Download
CmdTab-<version>.zipfrom the latest release, unzip it, and move CmdTab.app to your Applications folder. -
CmdTab isn't notarized by Apple (notarization needs a paid Apple developer account, which this free project doesn't use), so macOS blocks it the first time. To allow it, run this once in Terminal:
xattr -dr com.apple.quarantine /Applications/CmdTab.app
Or, without Terminal: try to open CmdTab, then go to System Settings → Privacy & Security, scroll down, and click Open Anyway. (On macOS 15 and later, right-clicking the app and choosing Open no longer gets past this.)
-
Open CmdTab and grant Accessibility permission when asked (System Settings → Privacy & Security → Accessibility). It starts working as soon as you turn it on.
-
For window thumbnails and previews, also grant Screen Recording permission and relaunch CmdTab (see Views).
Each release lists the zip's SHA-256 checksum, so you can check your download with shasum -a 256 CmdTab-<version>.zip.
If you have Apple's free command-line developer tools (xcode-select --install), you can build CmdTab yourself. An app you build on your own Mac isn't blocked by Gatekeeper, so there's no step 2.
./install.sh # builds, signs, copies to /Applications, launchesThe first time you run it, install.sh creates a self-signed code-signing certificate called "CmdTab Local Signing" in your login keychain. macOS asks for your password to trust it, and may ask once whether codesign can use the key (choose Always Allow). Every build is then signed with that certificate, so the Accessibility and Screen Recording grants survive rebuilds. Then grant the permissions as in steps 3 and 4 above.
Builds are universal (Apple silicon and Intel).
./build.sh alone builds build/CmdTab.app with an ad-hoc signature, and ./build.sh install installs that. macOS treats each ad-hoc build as a new app, so you'd have to grant permissions again every time.
- While CmdTab is running with Cmd+Tab Shows Windows on, it turns off the system Cmd+Tab app switcher. It turns it back on when you quit CmdTab or uncheck Cmd+Tab Shows Windows.
- Permissions are tied to the code signature. When it changes (for example, the first
install.shrun after an ad-hoc build), the install resets the old Accessibility and Screen Recording entries and you grant them once more. To sign with your own certificate instead, setCODESIGN_IDENTITY. - Like the Windows default, only windows on the current Space (desktop) are shown, unless Include Windows from All Desktops is on. macOS's Accessibility API doesn't list windows on other desktops, so CmdTab finds them through windows it has already seen. A window that was opened directly on another desktop, and that you haven't visited since CmdTab started, may be missing until you visit that desktop once. Windows on other desktops can't be captured live, so thumbnails and previews of them show their last snapshot or the app icon.
