    Hi, maybe just try shutting down the computer, waiting about 30 seconds, and then restarting the computer and trying again.

    First follow the instructions in this support article.

    If an iPhoto or Aperture library is the source of your desktop pictures, it may need to be rebuilt, or you may need to update the application to the latest version.

    Otherwise, continue as below.

    Back up all data.


    In the Finder, hold down the option key and select


    Go Library


    from the menu bar. From the Library folder, delete the following item, if it exists: 


    • Caches/com.apple.systempreferences


    and move the following item to the Desktop:


    • Preferences/com.apple.desktop.plist


    Launch System Preferences and test. If you still have the issue, put the item on the Desktop back where it came from and post again. Otherwise, delete the item.

    Hi there Linc,

    I am in the finder but when I hold down the option key nothing happens?


    Have I missed a step? I am looking to use just one of my photos as a screensaver.
