Does anyone know of a way to uninstall/rollback a software update? My buddy is having a problem with his airport connection on his mbp since he installed, I believe it was, the 5.3.2 airport utility. He's saying that the system receives an i.p. address from the router and the whole lot, but no apps seem to recognize it. I wasn't able to get him into log viewer to check network activity so I don't exactly know whats going on. Anyone have any ideas?
