The Ultimate Guide to Setting Up Hot Corners on Mac Hot Corners is one of the most underrated productivity features built into macOS. It turns the four corners of your Mac’s screen into instant shortcuts, allowing you to trigger actions just by moving your mouse pointer. Here is how to configure and master Hot Corners to streamline your daily workflow. How to Enable Hot Corners
Setting up Hot Corners takes less than a minute through your system settings. Open the Apple menu in the top-left corner of your screen. Select System Settings. Click on Desktop & Dock in the left sidebar. Scroll down to the bottom of the right pane. Click the Hot Corners… button. Click the dropdown menu for any of the four corners. Choose your desired action for that corner. Click Done to save your changes. Available Actions Explained You can assign a variety of system commands to each corner:
Mission Control: Visualizes all open windows on your desktop.
Application Windows: Shows all open windows of the active app. Desktop: Hides all windows to reveal your desktop files. Notification Center: Slides out your widgets and alerts. Launchpad: Opens the full-screen app launcher grid. Quick Note: Opens a fresh note for rapid typing.
Start Screen Saver / Disable Screen Saver: Controls your display saver.
Put Display to Sleep: Locks your Mac instantly to save power. Lock Screen: Brings up the login prompt immediately. Pro-Tip: Prevent Accidental Triggers
The biggest complaint about Hot Corners is triggering them by accident when reaching for a menu or closing a window. You can easily fix this by requiring a modifier key.
When selecting an action from the dropdown menu, hold down the Command (⌘), Option (⌥), Control (⌃), or Shift (⇧) key—or a combination of them. The menu will update to show the key symbol next to the action. This means the Hot Corner will only activate if you push your mouse to the corner while holding down that specific key.
