Not in love with Apple’s customary mountain range, or night sky wallpapers? No problem! It’s quick and easy to give your Mac a customized look by changing the desktop background image to something you prefer.
You can select from a variety of other options already loaded by Apple, or use one of your own photographs. Whatever you choose, you can freshen up your look now by following the simple steps below.
How to change your background picture from Systems Preferences
You can set your desktop image to one of a variety of options that Apple has already preloaded onto your Mac:
1. Open the Apple menu and select “System Preferences.” It may also be pinned to your dock (it’s a grey gear).

2. Click on “Desktop & Screen Saver.”
3. On the left side of the Desktop panel select the Apple drop down and click on “Desktop Pictures.”
4. You can now choose the picture you want to use as your background image. You can also have the image change at regular intervals by ticking the “Change picture” option at the bottom of your page, then set the time interval from the drop down box. The background will go through all the photos in the “Desktop Pictures” folder.

If you want the order to be shuffled, then tick the “Random order” option box at the bottom of the page. Depending on your Mac OS version, you may be able to choose a “Dynamic Desktop” image. The “Dynamic Desktop” options will automatically change your desktop image based on the time of day.
You can also choose to use your own photos for the desktop background:
1. To use photos in your Photos app or Pictures folder, you can use the drop down option on the left side of the panel or you can add another folder by clicking the + in the bottom left corner.
2. Now, choose the location of the folder that contains the photo, or photos you want to use.
3. You can now select the photo you want to use from the options displayed, or select the “Change picture” option to have the background image cycle through all of the images in your selected folder. The time between changes can be set from the drop down menu and you can have the order shuffled by ticking the “Random order” box.
If you use multiple displays, you can also set a different image for each screen.
