ACTIVATE AND USE HOT CORNERS

FIND HOT CORNERS

As with most system tweaks in macOS, this one requires opening System Preferences. Once you’re there, click Mission Control and you’ll see a button for Hot Corners.

FOUR CORNERS

Click that button. In the panel that opens, the four corners of the desktop are represented as pop-up menus. Click one to see all the actions you can assign to that corner.

YOUR OPTIONS

Handy system shortcuts include showing Mission Control, Launchpad, or the current app’s windows. You can also start your screensaver, or alternatively put the display to sleep.

ACTIVATE ACTIONS

You only have four corners to play with, of course, so experiment with the line-up of actions. Pick actions from as many of the menus as you want. Click OK when done.

TEST THEM OUT

Any action you’ve assigned is activated automatically when the pointer reaches the corresponding corner, saving you remembering menu item locations or keyboard shortcuts.

DISABLE A CORNER

Hot Corners are very useful if you need to use a non-Apple keyboard or mouse. If you want to remove one’s action, though, set its corresponding pop‑up menu back to the — (dash) item.
