I noticed something weird when I go to: Code: About this Mac > More Info > System Report > Software > Installed Software Basically some applications appear twice in the list. For example a game that I have. It stopped working for some reason, so I uninstalled it and reinstalled it. Now it appears twice in the list, the one I installed yesterday and the one I installed earlier today after it stopped working. Is there a way to delete one of them? That may be the reason why the game wont work. Another weird thing is that iTunes appears in the list as well. They are both the same version and one was installed 30 minutes after the first one was. Note that Ive done a fresh install so the game is really the only thing I have installed since then. Maybe someone can enlighten me!
