These two are also the less battery intensive options, especially compared to changing images every 5 minutes. Two really nice options here are When logging in - which assuming your Mac only has the one user can be translated as on restart - and the other is When waking from sleep. Under this selection, you can set how often you want the picture to change, and if the order should be random or not. Under the Desktop tab, you can choose a Finder folder or an album from your Photos library. Start by opening System Preferences, and click Desktop & Screen Saver. Did you know that you can change your desktop background automatically on macOS? It’s very easy to do, and you can have it switch between a folder or album of photos too!
