How to enable hot angles on your Mac? 1. Open the system settings and enter "Desktop and Dock"; 2. Click the "Hot Corner" button; 3. Assign actions to each corner from the drop-down menu, such as Mission Control, desktop, screen saver, etc. Hot corners are the corners of the screen that trigger specific actions by mouse movement, suitable for quick access functions and save time. It is recommended to avoid the same diagonal setting operation when using it. Multiple monitors need to maintain consistent settings. If you frequently touch mistakes, you can set them to "none" or change corners. To turn off, just set the operation in the corresponding corner to "None".

Turning on Hot Corners on your Mac is a quick way to trigger Mission Control, Desktop view, screen saver, and more with just a mouse movement. It's handy if you want fast access without using keyboard shortcuts. Here's how to set it up.

What Are Hot Corners and Why Use Them?

Hot Corners are areas in each corner of your screen that activate specific actions when you move your mouse pointer into them. They're useful for quickly switching desktops, showing the desktop, launching Mission Control, or starting the screen saver. If you're someone who uses multiple apps at once or likes to keep things tidy, Hot Corners can save you time and clicks.

How to Enable Hot Corners on macOS

To set up Hot Corners:

• Go to System Settings (or System Preferences on older macOS versions)
• Click on Desktop & Dock
• Scroll down to find the Hot Corners button and click it

From there, you'll see four corners listed. For each one, you can choose an action from a dropdown menu like:

• Mission Control
• Application Windows
• Desktop
• Screen Saver
• Lock Screen
• Notification Center
• Dashboard

You can assign different actions to each corner based on what makes sense for your workflow.

Tips for Using Hot Corners Effectively

Some setups work better than others depending on how you use your Mac:

• Avoid putting the same action in opposite corners — it might get confusing
• Use “Desktop” in one corner if you frequently minimize windows
• Try “Mission Control” in another corner to manage desktops and full-screen apps
• If you have a multi-monitor setup, Hot Corners work on all displays, so be consistent across screens

Also, if you accidentally trigger a Hot Corner too often, consider changing that corner's action to "None" or picking a less-used corner for that function.

Turning Off Hot Corners When You Don't Need Them

If you ever want to disable a Hot Corner, just go back to the settings and select None from the dropdown for that corner. You don't need to turn off all of them at once — only the ones that aren't working for you anymore.

That's basically all there is to it. Not complicated, but definitely useful once you get the hang of it.
