What are the common corners on macOS and how to set it up

macOS comes preloaded with many features, and while many of these are easy to locate and use, some are hidden behind several screens. However, this does not make them any less useful. These hidden features often turn out to be some of the best you can use to increase your productivity and get things done faster on your Mac.

Hot Corners on Mac is one of those features that doesn’t get much attention. It allows you to turn ordinary screen corners into interactive corners that perform tasks for you. You can assign a task to each of the four corners on your Mac. Then, when you bring the mouse pointer to any of these corners, the pre-specified actions are automatically triggered.

Why use Hot Corners on a Mac?

Hot Corners has many different uses depending on the tasks you assign to all four corners of the machine. If one or more of these tasks are things you launch frequently on your Mac, this feature can save you a lot of time.

It also helps you quickly return to your Desktop no matter where you are on your Mac. If you are a Windows user, you may know this feature when you click on a small pane in the lower right corner to bring up the Desktop.

How to Use Hot Corners on Your Mac

Using Hot Corners is as easy as taking the mouse pointer to any corner of your Mac.

When your Mac detects that your cursor is in one of the corners, it immediately triggers the action specified for it. You should see your screensaver, Desktop or something else depending on what you chose for the corner.

How to add custom keys to call hot corners

While the Hot Corners feature allows you to quickly access some of your macOS features, there is an issue that some of you may encounter. Since these corners are called out as soon as you bring the cursor there, you can sometimes trigger them accidentally.

Your Mac knows situations like this, and so has a feature that lets you add a key modifier to call Hot Corners. That means you can assign a key to these corners and only when you press this key and bring the cursor to the corner the action will launch.

You can do that by going to the same Hot Corners configuration pane.

  • Click the drop-down menu for any corner.
  • While the menu is still open, press and hold Change, Control, Right to buyor Request and then select an option.

Your Hot Corners will now only activate when you press and hold the specified key and bring the pointer to one of the corners on your Mac.

How to Disable Hot Corners on Mac

If you don’t want to use Hot Corners on your Mac for some reason, you can turn it off from the very menu you used to configure it.

  • Open Hot corner configuration pane.
  • From the drop-down menu on your screen, select the last option which is nothing but (minus). Then click ALRIGHT.

All corners should now have a null task assigned to them, meaning accessing them on your screen won’t take any action.
