How to Set Up and Control Hot Corners on Mac Like a Pro

If you’re a Mac user, you’ve probably heard of Hot Corners—a handy macOS feature that lets you assign specific actions to the four corners of your screen. With just a quick flick of your mouse, you can activate Mission Control, launch the Screen Saver, open Notification Center, or even create a QuickNote. It’s a time-saving trick that makes navigating your Mac feel effortless.

But let’s be honest: Hot Corners can sometimes be a little too sensitive. Ever accidentally triggered a Hot Corner while working on a smaller MacBook screen? Suddenly, your apps are flying everywhere, and you’re left scrambling to regain control. Don’t worry—there’s a simple solution. By using modifier keys, you can take charge of your Hot Corners and prevent those frustrating mishaps. Here’s how to set it up like a pro.

What Are Hot Corners and Why Use Modifier Keys?

Hot Corners are a macOS feature that turns each corner of your screen into a shortcut for specific actions. For example, you can set the top-left corner to activate Mission Control or the bottom-right corner to start your Screen Saver. It’s a fantastic way to streamline your workflow and access essential functions quickly.

However, the downside is that Hot Corners can be triggered accidentally, especially on smaller screens or if you lose track of your cursor. This is where modifier keys come in. By assigning a key like Command, Shift, or Option to a Hot Corner, you ensure that the action only activates when you hold down the key. It’s a small adjustment that makes a big difference in usability.
