Desktop Pictures

OS X comes with a mountain of desktop pictures, ranging from National Geographic–style nature photos to plain solid colors. To install a new background picture, first choose one of the image categories in the list at the left side of the window, as shown in Figure 17-10.

Your choices include Desktop Pictures (muted, soft-focus swishes and swirls and a few nature shots—like the new El Capitan shots); Nature (bugs, water, outer space); Plants (flowers, soft-focus leaves); Art (a collection of famous paintings by Monet, Degas, Seurat, and other canvas superheroes); Black & White (breathtaking monochrome shots); Abstract (swishes and swirls with wild colors); Patterns (a pair of fabric closeups); and Solid Colors (simple grays, blues, and greens).
