It’s worth noting that if you’re not going to be using your Mac for a while, you can instead set macOS to turn off your display automatically or simply put the Mac to sleep, which can help you save power over time. You can use them for fun things like displaying a custom message, showing album artwork, or playing slideshows of your favorite photos when you’re not using your machine. The theory behind screen savers is that they continuously display a fluid, moving image that causes the image to change so that no one area will get burned in.Įven if you’re not worried about burn-in (such as with LCD panels in most modern monitors), screen savers are also a playful way to customize your Mac. Some types of monitors and TV sets you might have hooked to your Mac can suffer from burn-in, which means certain areas of the screen will degrade in image quality over time if they continuously display the same static image. If you’d like to add some personal graphical flair to your Mac-or prevent burn-in on an OLED, plasma, or CRT display-macOS lets you select from a number of attractive screen savers.
