I've searched for this but can't seem to find anyone with this problem (which worries me): I tried an install of 10.6 today. Everything went fine (although it took a lot longer than I was expecting), until the final restart. I get the apple on the silver screen, and the spinning clock (or whatever, not the colored wheel), and that's it. It just spins forever but doesn't finish the reboot. Has this happened to anyone else? What do I do now?
