How to Set Up Mac Hot Corners for Faster Navigation

Hot Corners are a hidden productivity feature on every Mac. The idea is straightforward: when you push your mouse cursor all the way into one of the four corners of your screen, something happens automatically. You can assign a different action to each corner, turning corners into instant shortcuts.

Many Mac users don't know Hot Corners exist, but once you set them up, they become part of your muscle memory. Common uses include showing Mission Control (all your open windows at once), revealing your Desktop, locking your screen when you step away, or putting your display to sleep without hunting for a menu.

Here's how to set them up. Open System Settings (the gear icon in your Dock or Apple menu), then go to Desktop & Dock. Scroll down to the bottom and click the "Hot Corners" button. A small window appears showing all four corners. Click the dropdown for any corner to pick an action.

The available actions are: Mission Control (shows all open windows spread out), Application Windows (shows all windows for the current app), Desktop (hides all windows and shows your Desktop), Launchpad (the full-screen grid of all your apps), Screen Saver (starts the screen saver immediately), Display Sleep (turns off the screen but doesn't log you out), Lock Screen (locks your account), Notification Center (slides in the right-side panel), and Quick Note (opens a floating notepad).

A good starting setup for many people: top-left corner for Mission Control, bottom-left for the Desktop, bottom-right to Lock Screen, and top-right for Notification Center. But experiment — there's no wrong answer.

One important option: you can require holding a modifier key (Shift, Option, Command, or Control) before the Hot Corner fires. Hold Option while selecting an action in the dropdown to add that requirement. This prevents accidental triggers when you move your cursor near a corner while working normally. If you find Hot Corners fire too often by accident, adding a modifier key solves that completely.

Hot Corners work alongside trackpad gestures — you can have both active at the same time without conflict.
