How to switch between windows of the same app on Mac
Command-Tab gets you to an app. To move between that app's windows, try Command and the grave-accent key (`). Want to see the windows before choosing? Control–Down Arrow opens App Exposé for the current app. If those controls already feel right, you don't need another utility.
First, check whether you're looking for an app, a window, or a tab
Two Safari windows still share one Safari icon in Command-Tab. And several browser tabs inside one window are a different thing again: use the browser's own tab controls for those.
| What you want to do | Start here |
|---|---|
| Get back to another app | Command-Tab |
| Move between windows in the current app | Command + grave accent (`) |
| See the current app's windows together | Control–Down Arrow |
| Get an overview of the desktop's open windows | Control–Up Arrow, for Mission Control |
These are the standard shortcuts. The grave-accent key varies with your keyboard, and shortcuts can be reassigned or handled differently by an app. Apple's keyboard shortcut guide explains the defaults.
If you want to pick by sight, use a preview
Window titles are useful until three of them look almost the same. OmniDock can show live or static thumbnails when you hover over a running app's Dock icon. Click the preview of the window you want to bring it forward.
For setup and permissions, see Dock window previews. Previews represent separate windows, not every tab inside them.
Prefer the keyboard? The two preview options do different jobs
OmniDock can add static previews above the app selected in Command-Tab. The system's app switcher remains the app switcher; the extra image helps you recognize what's open.
Option-Tab is a separate, window-level picker. Enable Show Dock Window Previews first, then Alt-Tab Preview under Window Preview. If another tool already uses Option-Tab, disable that binding there before trying it in OmniDock. The Support page covers the permission and shortcut checks.
An app hotkey is different again: it launches or brings forward one assigned app. It doesn't ask you to choose one of that app's windows.
If a window is missing, check its state
Bring the app forward and restore the window before checking again. A hidden or minimized window may have only an earlier snapshot available. Full-screen windows, protected content, Spaces, and the app itself can affect what macOS makes available for preview. A missing thumbnail doesn't mean the document has closed.
Try it with two windows you actually use
Open two separate windows in a familiar app, keep them on the same desktop, and switch with the built-in shortcut. Then try App Exposé. If you still prefer choosing from the Dock, try the preview workflow with those same windows. Test any full-screen or multi-display setup you rely on before changing your everyday routine.
