Hi AppleInsiders! I use to post on here a lot a while back but it seems my account was lost so made a new one! Basically, a few weeks ago I transported my iMac from one city to another, done this a few times always strapped it in good etc. Now immediately after getting home and setting up again, after booting my mac all was well until these lines just appeared on the screen and the computer shut down then went into a loop like you've probably seen with a lot of macs...
