How to set up and use active corners on Mac.

macOS, Apple’s desktop operating system, is packed with useful features, some of which may go unnoticed (in addition to these 9 macOS easter eggs that very few people know about). One of these features, known as hot corners, offers us a very efficient and quick way to interact with our Mac and perform tasks just by moving the mouse. Let’s see how to set up and use this feature to improve our productivity.

Active Corner Settings

Active corners allow us to assign specific actions to each corner of our screen. This means that when we move the cursor to a corner, we can trigger an action such as opening the Notification Center, starting the screensaver, or accessing Mission Control, for example. The interesting thing is that we can customize these actions according to our needs and work habits. We will do it like this:

1. In the Apple menu (), choose System Preferences.
2. Go to Desktop & Dock.
3. In the bottom, click on Hot Corners.
4. For each corner, choose the action you want to perform from the dropdown menu.
5. Click Done to save the changes.

We have 11 options for each corner: Mission Control, Application Windows, Desktop, Notification Center, Launchpad, Quick Note, Start Screen Saver, Disable Screen Saver, Put Display to Sleep, Lock Screen, or assign no action. Let’s also note that we can hold down the Command, Shift, or Control key while choosing the option and then have to press it at the same time as we move to that corner. With this system, we will prevent actions from being activated without actually wanting them.

Using active corners

The use of active corners is really intuitive and can significantly simplify the way we interact with our Mac. For example, if we assign the Application Windows function to the top right corner, when we move the cursor there, all open windows of the current application will be displayed, making it easier to switch between them.

If one of our corners activates Launchpad, we can drag a file from a Finder window to the icon of an application in Launchpad, like Notes, to create a new note with that file through the corner.

We can also mention the configuration of the Screen Lock corner, very useful when we need to quickly step away from the desktop. A simple movement towards that corner and our Mac will lock, protecting our privacy.

If we work with multiple screens, the active corners work independently on each of them, so we have even more options. If we prefer them to act as if it were a single large screen, we just have to align the monitors in the System Settings, within Displays.

Active corners are a really capable and too often underestimated feature of macOS. Allowing us quick and customizable access to the functions we use most – like playing ambient sounds on Mac – and optimizing our workflow with it, it’s something that, once properly configured and tested, becomes essential.
