What are hot corners on Mac?

Hot corners allow you to use the four corners of your Mac’s screen to trigger specific actions as soon as you move the pointer in a particular corner. Besides, the bottom-right corner is set to Quick Note by default. Go ahead and try moving your pointer at the screen’s bottom right. You should be able to see a small box. Click it to open a new note, which can come in handy whenever you need to jot an idea quickly. But you can customize each hot corner as per your need.

Why use hot corners?

If you’re like most people, your Mac’s desktop is likely cluttered with opened browser windows and apps. This may make it difficult to find a specific window, view your desktop, or hide all your windows instantly. With a flick of a wrist, hot corners on your Mac instantly lock your screen, hide sensitive information on your desktop, and perform several other actions. The feature eliminates the need to memorize several keyboard shortcuts or click around toolbars to navigate your desktop.

How to enable hot corners on Mac

Alternatively, you can also set it up by going to the Apple menu → System Preferences → Mission Control → Hot Corners.

Actions you can set up on hot corners

You can select from ten different actions for your Hot Corners:

1. Mission Control

If you run multiple windows and apps simultaneously on your Mac, Mission Control helps you stay on top of your game by giving you an overview of all the items currently open on your Mac. Assigning it to a Hot Corner is just one of several ways to access Mission Control on your Mac.

2. Application Windows

This gives you an overview of all the opened windows for a particular app. For some apps, you may also be able to see recently accessed files. You can switch between different app thumbnails in this view.

3. Desktop

If you’re like me, you put every important file on your desktop for easy access. However, accessing them may not be as easy when your desktop is cluttered with too many windows. This action moves all the windows aside so that you can access your desktop. The windows return as soon as you click a file.

4. Notification Center

This is seldom used as a Hot Corner since you can always access the Notification Center through the menu bar. 

5. Launchpad

This hot corner opens the Launchpad, which looks and feels like an iPad or an iPhone’s Home screen. Launchpad is useful for finding, organizing, deleting, and accessing your apps. You can also add the Launchpad icon on your Dock, so this might not be as useful as a hot corner. However, if you want a quick way to use the Launchpad, this is an excellent way to do it.

6. Quick Note

As mentioned, this Hot Corner is assigned to the lower right hot corner by default and allows you to open a note instantly. You can find your Quick Notes in a dedicated folder on the Notes app.

7. Start Screensaver

While screensavers are not commonly used anymore, this can be a handy feature if you want to hide the contents of your desktop as you walk away for several minutes. This action immediately triggers your screensaver to appear and overrides the preset time that your Mac must stay idle before a screensaver appears.

8. Disable Screensaver

If you have set your screensaver to turn on after several minutes, it may appear at a time that you don’t want it to— like when you’re staring at your desktop, thinking hard and long about the best way to word an email. This hot corner action buys you some time and prevents your screensaver from coming on.

9. Put Display to Sleep

If you’d rather put your screen to sleep instead of using a screensaver to save energy, you may prefer this action. This hot corner lets you override the Turn display off after in System Preferences → Battery and allows you to turn off your display instantly.

10. Lock Screen

This hot corner action allows you to immediately put your screen to sleep and requires a password to reaccess it. Locking your screen may come in handy when dealing with sensitive information or simply enjoying some additional privacy.

How to prevent triggering hot corners by accident

One of the frequent complaints against hot corners is the tendency to trigger them by accident. To prevent this, you can add modifier keys, requiring you to press specific keys while swiping to a corner to activate the action. For this, you can use the Command, Shift, Option, Control, or a combination of these keys. Just click the popup menu and hold any of these keys to add modifier keys with the hot corner. Wrapping up… Using hot corners is an efficient way to use your Mac and will save you a great deal of clicking over time. Are you using hot corners? Which actions do you prefer and why?
