I recently bought a new 15" PowerBook, and within the first day of use my System Preferences stopped working. I tried clicking the alias on the dock, but it changed to a question mark. I tried opening it through the apple menu, but no response. I can't find it in my applications folder or when doing a search, or when doing software restore from the CD either. Can anyone help me out or give me some advice what to do? My problem sounds exactly the same as the one on the Mac Fix-It Forum: http://www.macfixitforums.com/php/s...er=588884&page=0&view=expanded&sb=5&o=&fpart= Thanks!!
