While some people are content to use whatever default desktop background Apple puts in the latest version of Mac OS X, others get bored easily and want to see something new every so often. Fortunately, there’s a quick and easy way to do that automatically so that you don’t have to bring up System Preferences each and every time you want to change the desktop background. Here’s how to do it:
1) Launch System Preferences from the Dock or from Apple Menu > System Preferences.
2) Click on the Desktop & Screen Saver button, which is the second button in the top row of System Preferences (see below).
3) Select the source of the images you wish to see on your Mac desktop. This can be the standard folder of beautiful desktop images supplied by Apple, solid colors, a folder of images from either iPhoto or Photos, or any other folder of images that you select from the list on the left side of the Desktop & Screen Saver system preferences pane (see below).
4) Check the “Change picture” box, then select a time duration from the pop-up menu (see below). Images can be changed as often as every five seconds or as rarely as each time you log into your Mac.
5) Once your selection of source photos and duration of showing the desktop image has been made, just click the red close button on the System Preferences window to save the setting change.
Automatically changing the desktop background on a large-screen Mac like a 27-inch 5K Retina display iMac can be a great way to display the best of your photography.
