The Search for Efficiency
If you use a Mac all day for work, much of your time is spent executing repetitive navigation tasks. You repeatedly minimize windows to find a file on your desktop, you constantly open Mission Control to see all your open applications, or you repeatedly click the Apple menu to put your display to sleep when you step away from your desk.
While you can learn keyboard shortcuts for these actions (like Command + F3 for the desktop), keyboard shortcuts require taking your hand off the mouse or trackpad, which breaks your physical flow. Apple has built a vastly superior, nearly invisible feature into macOS to solve this: Hot Corners.
Hot Corners allows you to turn the four physical corners of your Mac’s screen into hidden buttons. By simply flicking your mouse cursor into a specific corner, you can instantly trigger a system action without clicking a single button or pressing a single key. In this guide, we will set up and customize these hidden triggers.
How to Enable and Configure Hot Corners
The Hot Corners menu is tucked away inside the Desktop & Screen Saver settings (or Desktop & Dock in macOS Ventura and later).
- Click the Apple menu in the top-left corner of your screen and select System Settings (or System Preferences).
- Scroll down the left sidebar and click Desktop & Dock.
- Scroll all the way down to the bottom of the right-hand pane and click the Hot Corners… button.
A small window will appear displaying a graphic of your monitor. In each of the four corners, there is a dropdown menu. These menus dictate what happens when you move your cursor into that specific corner.
Choosing the Best Actions
When you click a dropdown menu, you are presented with several options. Here is a breakdown of the most useful actions to assign:
1. Desktop (The Most Useful Corner)
If you are working in a maximized browser window and someone AirDrops you a file, or you need to grab an image you saved to your desktop, you normally have to manually drag your browser window out of the way. If you assign “Desktop” to your bottom-left corner, simply flicking your mouse down and to the left will instantly slide all open windows off the screen, revealing your bare desktop. Flick your mouse back into the corner, and the windows instantly slide back into place.
2. Put Display to Sleep (The Security Corner)
If you work in a busy office or a coffee shop, you should lock your Mac every time you step away to use the restroom. Assigning “Put Display to Sleep” or “Lock Screen” to the top-right corner allows you to instantly secure your computer with a single flick of the wrist as you stand up.
3. Mission Control
If you have twenty windows open across five different applications, finding the specific window you want can be chaotic. Assigning “Mission Control” to the top-left corner allows you to flick your mouse and instantly see a bird’s-eye view of every single open window, neatly tiled across your screen so you can click the one you need.
4. Quick Note
Introduced in recent versions of macOS, the Quick Note feature is excellent for jotting down a phone number or a quick thought without opening the full Notes app. Assigning it to the bottom-right corner allows you to instantly summon a small digital sticky note from the edge of the screen.
Preventing Accidental Triggers (The Modifier Key Trick)
The biggest complaint new users have about Hot Corners is that they accidentally trigger them when trying to click the Apple Menu (top left) or close a window. There is a hidden trick to prevent this completely.
While you have the Hot Corners setup window open, do not just select an action from the dropdown menu. Instead, press and hold the Command (cmd), Option (alt), or Shift key on your keyboard while you click the dropdown.
You will see the modifier key symbol appear next to the action name (e.g., ⌘ Desktop). This means the corner will only activate if you are physically holding down the Command key when you move your mouse into the corner. This eliminates 100% of accidental triggers while keeping the feature incredibly fast.
Conclusion
Hot Corners are the ultimate expression of macOS design philosophy: powerful, frictionless, and invisible until you need them. By taking two minutes to assign “Desktop” and “Put Display to Sleep” to your corners, you will permanently eliminate dozens of unnecessary clicks from your daily routine.
