HOW TO Use Hot Corners on your Mac
Open Preferences
Hot Corners is in System Preferences > Desktop & Screen Saver, and it’s also in System Prefs > Mission Control, too. It doesn’t matter which one you choose: they’ll both take you to the same options.
Find the button
If you went for the Screen Saver option, you’ll need to click the Screen Saver button. You should now see the Hot Corners button at the bottom right. If you went the Mission Control route, it’s at the bottom left.
See what’s set up
When you click the Hot Corners button you’ll see a pop–up window with four menu selections. On Monterey, the bottom right one may already be filled in with the Quick Note feature, which is allocated to the bottom right.
Test the corner
Let’s try that one first. Move your mouse or trackpad cursor to the lower right of your screen and you should see a Quick Note corner appear. If you keep the cursor there or click, the note will open up for you to edit.
Change the corner
You don’t have to stick with Quick Note here. Click the menu for the lower–right corner to see more options including screen saver options, Mission Control and Launchpad, and some display options too.
Add some more
Now make your way around the other corners to add more Hot Corners. If the menu shows a dash (“–”) it means that corner isn’t active as a Hot Corner. You can disable any Hot Corner by choosing that option.
Test it out
Here, we’ve made the top–left corner show current application windows, in this case for Safari; moving the cursor into the top left temporarily hides everything but the currently selected app’s windows.
Disappear desktop
Now, we’ve assigned Desktop to a Hot Corner; moving over the corner hides the apps so that we can see what is currently on our desktop. With dual displays this shows the desktop for the display with the Hot Corner.
Launch Launchpad
In this example, we’ve chosen to activate Launchpad from our Hot Corner, providing quick access to all our apps and to the Dock too. It’s a great example of how Hot Corners can make your Mac more you.
