Hey Ok I'm doing this from my touch so there maybe spelling and typos along the way. Anway, I ran software update this morning and began downloading, all went well then it asked to Restart. So I did. Now its sitting at the leopard space wallpaper with the circle spinning. It's been like this now for 45min and the screen has now dimmed and I can't move the mouse. What should I do? Hold the power button?
