To change your desktop wallpaper in OS X, follow these steps:

  1. Click the Desktop to make the Finder active.

  2. Select Preferences under the Finder menu.

  3. Change the wallpaper by pressing the Select Picture button.

By default, this opens the Desktop Pictures folder in the Library directory, but you can browse to anywhere on your computer to find a suitable JPEG or PICT file.
