To see all open windows on a Mac, use Mission Control by pressing the F3 key, swiping up with three or four fingers on the trackpad, or clicking the Mission Control icon in the Dock, which displays all windows across apps and desktops; 2. For windows of a single app, hover over the app’s icon in the Dock, right-click, and select “Show All Windows” or press and hold the icon until windows appear; 3. Use the keyboard shortcut Control Down Arrow to view windows of the currently active app, which can be customized in System Settings; 4. While Command Tab switches between apps, holding Command and releasing Tab shows a preview of individual windows for quick selection; Mission Control is best for system-wide visibility, while App Exposé is efficient for single-app window management.

To see all open windows on a Mac, you can use one of several built-in methods depending on your preference and workflow. Here are the most common and effective ways:

1. Use Mission Control

Mission Control gives you a bird’s-eye view of all open windows across all apps and desktops.

• Press the Mission Control key (usually F3 or labeled with two overlapping rectangles on the keyboard).
• Or swipe up with three or four fingers on the trackpad (depending on your settings).
• Alternatively, click the Mission Control icon in the Dock or use a designated hot corner.

Once activated, you’ll see all open windows arranged by application, making it easy to locate and switch to the one you want.

2. Use App Exposé to See Windows for a Single App

If you want to see only the windows of a specific app:

• Hover over the app’s icon in the Dock and right-click (or Ctrl-click).
• Select “Show All Windows” from the menu.
• Or press and hold the app icon in the Dock until its windows appear in Exposé.

This is useful when an app has multiple windows open and you want to quickly pick one.

3. Keyboard Shortcut for App Windows

You can also use a keyboard shortcut to activate App Exposé:

• Press Control Down Arrow (or Control Up Arrow, depending on settings).
• This shows all windows for the currently active app.
• Navigate between them using arrow keys or click to select.

Note: You can customize this shortcut in System Settings > Keyboard > Keyboard Shortcuts > Mission Control.

4. Use Command Tab to Switch Apps (Limited Window View)

While Command Tab only shows app icons (not individual windows), releasing the shortcut while still holding Command will show a preview of the app’s windows, letting you switch directly to one.

For most users, Mission Control is the fastest way to see all open windows at once. If you're focused on one app, App Exposé (via Dock or keyboard) is more efficient.

Basically, it comes down to what you’re trying to find — all windows system-wide or just within a single app. These tools make it easy once you know the gestures or shortcuts.
