    MacOS is filled with features that can help streamline your workflow and improve your productivity when using your computer. And while you’re probably well acquainted with keyboard shortcuts, which there are a lot of, there’s a low-key feature you can also use to quickly run a number of actions — known as hot corners.
    Using your mouse, you can move your cursor into any one of the four corners of your Mac to run several system actions, hide your open windows, lock your screen, show your notifications, put your computer to sleep and more. However, this feature isn’t enabled by default, so you must configure it before using.
    Check out the story below to learn what these hot corners can do and how you can set them up on your Mac.
