What preferences (plist) can you trash to eliminate startup problems? The menu bar starts to draw under the Spotlight icon, about 1/2" and then he computer freezes. The rest of the menu bar is missing but the Dock and the spinning beach ball is there. I threw away: com.apple.finder.plist, com.apple.LaunchServices.plist and com.apple.loginwindow.plist from ~/username/library/preferences. This helped but what I am looking for is there a list of preferences we could make up to clean house, so to speak, to help the OS rebuild the startup prefs.
