How to Disable the macOS ‘Show Mission Control’ Keyboard Shortcut

The Accidental Workspace Switch

Mission Control is macOS’s built-in window management system, providing a bird’s-eye view of all your open applications and virtual desktops (Spaces). By default, Apple assigns specific keyboard shortcuts to instantly trigger this view, most commonly utilizing the F3 key or a combination involving the Control key (like Control + Up Arrow). While this provides rapid access to window management, it can become a significant source of frustration depending on your workflow.

If you are a heavy keyboard user, a programmer utilizing a complex IDE, or a gamer, you likely rely on a vast array of custom keyboard shortcuts. The default Mission Control shortcuts frequently conflict with application-specific hotkeys. For example, you might try to execute a multi-line selection in a code editor using the Up Arrow, only to accidentally trigger Mission Control, violently yanking your focus away from your code and throwing all your windows into an overview grid. If you prefer to trigger Mission Control using only trackpad gestures (like a three-finger swipe up) or if you simply don’t use the feature at all, you should disable the keyboard shortcut to reclaim those keys for your own applications.

How to Turn Off the Mission Control Shortcut

You can unbind the Mission Control hotkeys via the Keyboard Shortcuts settings.

1. Click the Apple Logo in the top-left corner of the screen and select System Settings… (or System Preferences).
2. In the left-hand sidebar, scroll down and click on Keyboard.
3. In the right-hand pane, click the Keyboard Shortcuts… button.
4. In the new window that appears, select Mission Control from the left-hand list.
5. Look at the right-hand pane for the specific checkbox labelled Mission Control.
6. Uncheck the box next to it to completely disable the shortcut.
7. Click the blue Done button to save your changes.

Pressing the previously assigned shortcut (e.g., F3 or Control+Up) will no longer trigger the Mission Control overview, allowing your active applications to register the keystroke instead.
