Change the Desktop Wallpaper Automatically in Mac OS X
Can’t decide which wallpaper to use as your desktop background? Me neither. Fortunately there’s a setting in Mac OS X that causes the desktop picture to change itself automatically at a user selected time interval, ranging from every 5 seconds to once a day or upon system wake.
- Open “System Preferences” from the Apple menu and click on “Desktop & Screen Saver”
- Click the checkbox next to “Change picture” and set the time interval, the default is a new background every 30 minutes
- Select “Random order” as well for best results
Whatever your background picture was set to will be changed immediately, and then it will change again at the time interval you selected.
Changing every 5 seconds can be a bit neurotic, but if you have enough similarly themed wallpapers to go with, it can create a feeling similar to the living desktops of Android fame.
Another option is to use a free app like Wallpaper Wizard Lite, which will automatically download new desktop pictures in addition to changing them for you.
