Unable to Change Background on Mac


On your Mac, nothing happens when you change your Desktop wallpaper.


The preference that manages this setting has become corrupt.


  1. Go to your User Library folder.
  2. Open the Preferences folder.
  3. Delete the file “com.apple.desktop.plist”.
  4. Logout and log back in.

You should now be able to change your background again.

  1. Thank you so much! I had tried everything; going onto Apple’s forums, trying other computer help forums, etc and your’s was the only one that worked. Thank you again for sharing your knowledge.
