Not only does macOS let you set any picture in your Photos library as a desktop wallpaper, you also can use your Moments, Collections, Years, Places, Faces, Albums and Shared iCloud Albums as your desktop wallpaper, as we recently explained.
Wouldn’t it be nice if you could select a set of photos to use as your screen saver, too? In this tutorial, you’re going to learn how to set the Photos library as a screen saver on your Mac with just a few clicks.
How to set Photos library as a screen saver on your Mac
1) Launch System Preferences on your Mac.
2) Click the Desktop & Screen Saver preference pane.
3) Click the Screen Saver tab.
4) Select a desired screen saver in the lefthand column.
5) In the righthand column, click the pop-up menu next to Source and select a recent photo event, or choose the Photo Library option.
6) Now choose a set of photos to use for the screens saver. You can select a Moment, Collection, Year, Place, Face, Album or Shared iCloud album to use as your Mac’s screen saver, or click individual photos to use for the screen saver.
7) If you want the screen saver to cycle through the selected photos in random order, click the Shuffle Slide Order box.
8) To adjust when the screen saver starts, click the pop-up menu next to Start After and select an option.
The available choices include 1 Minute, 2 Minutes, 5 Minutes, 10 Minutes, 20 Minutes, 30 Minutes and One Hour.
To see your screen saver in action, click the Preview button.
To have the screen saver activate when you reach one of the screen corners with the mouse pointer, click the Hot Corners button, select a screen corner and then choose the Start Screen Saver option in the pop-up menu.
Tip: For security reasons, you can select the Require Password option in System Preferences → Security & Privacy → General, which will require you to enter your account password after a predetermined period of time has passed since your Mac went to sleep or screen saver began.
