Talk about bad luck! My friend left for Switzerland a couple of days ago. She lands there and while skyping with her today, I tell her to update Snow Leopard via software update since the last update she got to was 10.6.3. She texts me a few minutes ago that her macbook pro (mid 09, 13'') is not booting up: Apple logo and spinning wheel stay there. This never happened to me so I have no idea what she can do with being all the way in Switzerland with her MBP as her only laptop and no installation discs with her. I told her to boot into safe mode as that's the first thing that comes to mind and to attempt a disk repair from there. If that fails, what should her next step be?
