That's what I did, I ran NBI with all the numbers, ran the update, ran NBI again, and it says 10.6.7, no problems. IDK if I needed to run NBI b4 the update, but I thought what the heck. It is working fine, every once in a while after a hibernate, sound won't work and I still get the hibernate image too old, but other than that, working great. I was worried since I did skip an update in the past when I went straight from new install to update and got the terminal error. So I am extra careful now but it is working great. I have to go to the windows side of my dual boot once a month, if not for a program I would be 100% mac all the time.
