How to Disable Hot Corners on macOS: and Why you Might Wish to as a VoiceOver User

In this episode, Tyler demonstrates how to disable Hot Corners on macOS. Hot Corners are areas of the screen that perform a specified action when the mouse pointer is hovered over them. As a VoiceOver user who doesn't use the mouse, you might want to configure them to do nothing, so you don't inadvertently cause an action to be performed if you accidentally brush your fingers against the trackpad or use trackpad gestures to control VoiceOver. To do this, go to System Settings > Desktop & Dock > Hot Corners, and make sure the popup menu for each screen corner is set to hyphen (-) rather than any of the actions in the menu.
