hello, I wish my first post wasn't in the help section as I've lurked quite a bit but here goes. a friend of mine purchased a 27 inch late 2011 imac with lion, and asked if I could help transfer data to it from his late 2003 imac g4 (it has been updated to leopard). I started the new imac, set up a profile and passed on data migration at initial setup. I then grabbed a fire wire cable and after doing an update on the old imac(to make it compatible with Lion), ran migration assistant on both. The data transferred with no problems. The new imac then did 2 software updates, and we restarted it hoping to see the old profiles available. The new Imac booted to a grey screen with just an apple logo. that was it, and nothing else. I could safe boot into either profile, but from a normal startup, there was nothing.... just grey screen and apple logo I called apple tech support and was on the phone for an hour. The girl was nice and ran me through a battery of tests but to no avail. the hard drive check was fine, some permissions were out of wack, but we repaired. still didn't work. reinstalling the OS now, but wondering if anyone has ever had any of these issues or could offer advice? thanks in advance.
