I just got an iMac 27" i7 last week, which by the way, I love. But it's a pretty fresh install with nothing unusual on my drive and just some very basic and common applications as well as my music, movies, etc. So I went to download 10.6.3 and install seemed to go fine but it just hanged at the very end on "moving items into place" or somesuch. It stayed there for like 20 minutes with the blue bar moving maybe one or two pixel rows. Then the screen went black. I did a hard restart but the iMac wouldn't boot and just hanged on the loading screen several times. I'm doing a time machine restore now but am scared to reinstall 10.6.3. Anyone else having the same issue?
