A screensaver is typically activated automatically during a period of inactivity – like when you’ve stepped away from your computer for an extended period of time.

It’s easy to change your screensaver on a Mac computer, and you can even customize patterns and choose the images you want to feature.

You’ll also be able to set a password with your screensaver to protect your computer.
