I am on a MacBook Pro running 10.5.8 I have not been able to change the desktop wallpaper for approximately 6 months. I have created another user account on the computer and the wallpaper can be changed in that account. I have read many threads in this forum and elsewhere and this is what I have tried so far but none of it has yet worked: 1: I have deleted the following and then restarted - /Users/[home folder]/Library/Preferences/com.apple.desktop.plist /Users/[homefolder]/Library/Preferences/ByHost/com.apple.screensaver*.plist This got rid of the desktop I had, but now I have the default background of Aurora and cannot change it. 2: I have also deleted - /Users/[homefolder]/Library/Preferences/ByHost/com.apple.screensaver*.plist -com.apple.screensaver.plist -com.apple.screensaveritunesartwork.plist -com.apple.screensaversildeshow.plist 3: I have also tried this: /System/Library/Frameworks/ScreenSaver.framework/Versions/A/Resources/Computer Name.saver I went there and double clicked and then clicked install. Nothing appeared to change. Any thoughts about what else I can try? Thank you!
