OSX: Stop Triggering Those Hot Corners

| TMO Quick Tip

OS X's Hot Corners feature is a way to add quick access to some Mission Control features, but if you drag your mouse pointer into one of your Hot Corners by accident, you may inadvertently activate that feature when you didn't want to. Adding a modifier key to your Hot Corners can easily prevent that accidental activation. Here's how.

Open System Preferences on your Mac, and then click the Mission Control preference pane.

Next, click 'Hot Corners...'

Choose the corner you want to make 'Hot.' In the list, you'll see a handful of options that can be super useful to have quick access to. Activate one, and dragging your mouse to that corner of your screen will quickly activate that feature.

To add the modifier key, simply hold down the keyboard key that you would like to associate with the Hot Corner and make your action selection. This works with the Shift, Control, Option or Command keys.

I’m a big fan of using this setup to put my Mac’s display to sleep. My home office is in the bedroom, and as much as I enjoy my photo screensaver, when it’s time to hit the sack, I want that screen to be dark.

Brilliant Jared, thanks.
I often accidentally activate the top hot corners when trying to point to the menu bar.
No more!

OMG, thank you Jared!  I love using hot corners but accidentally activating them drives me cra-cra.  Not anymore!
