How to Change Desktop Wallpaper on a Mac

The background image on your computer's desktop is the first thing you typically see when you boot your computer, and can be anything from a picture of a friend or family member to a generic color you enjoy. If you have a Macintosh computer, changing your background image is very easy to do and only takes a few minutes.

Instructions

1. 

   Press the Apple icon at the top left hand side of the screen and then select "System Preferences" from the available options.

2. Choose "Desktop and Screen Saver" from the System Preferences menu.

3. 

   Select "Desktop" from options at the top of the display box.

4. 

   Select a picture for the available options. The box on the far left of the screen will allow you to browse through the pre-loaded Apple images as well as any images that might be stored on your computer. Images will appear in the box on the right and can be selected by double-clicking.

5. Exit the menu by pressing the red dot in the top right corner.
