macOS comes preloaded with many features, and while many of them are easy to spot and use, some are hidden behind different screens. That doesn’t make them any less useful, though. These hidden features often turn out to be some of the best you can use to boost your productivity and get things done faster on your Mac.

Hot Corners on Mac is one such feature that hasn’t seen much of the spotlight. It allows you to turn normal screen corners into interactive corners that perform tasks for you. You can assign a task to each of the four corners of your Mac. Then, when you hover the mouse cursor in one of these corners, the pre-assigned tasks are automatically activated.
