Give your desktop a custom look
There are several ways to give your desktop—the background area of your screen—a custom look.
Change the picture you see on the desktop
In Desktop preferences, you can choose the picture that’s displayed on your desktop. Your Mac comes with dozens of desktop pictures to choose from, but you can also use your own pictures, or choose a solid color.

If you can’t settle on just one picture, you can cycle through all the pictures in a folder. Select the “Change picture” checkbox, then choose how often you want the picture to change—for example, every hour. This option may affect the performance of some apps, such as games, that use many graphics. To use just one picture again, des
