help help help help help! i did the most recent os update on my (G5 non-iSight) iMac through the software update thing but instead of restarting immediately i procrastinated, went on the internet a bit, deleted my trashcan and then restarted (i think there may have been an error message after deleting my trash). now when i power up all i get is the apple logo followed by a blue screen with welcome to Mac os X with a space for a progress bar (yet no bar appears) where it just seems to eternally hang. safe mode doesn't help anything, neither does starting from a jaguar CD, although i can access the iMac through firewire target disc mode. anyone have any suggestions?! it's my presumption that i have somehow deleted esssential start-up files by emptying my trash before restarting (despite not having put anything like that in my trash - is this even possible? if so, what an incredibly bad system!!!) thanks a lot mac community!
