Hi, after many hours browsing this forum I have decided to sign up ! I have a problem with one of the macs here at work - It wont get past the blue screen and the constantly spinning gear like icon. I have tried a few things like booting into safe mode which it wont ! I have also gone into single user mode and ran fsck which returned with everything is ok and verbose mode halts after line - /System/Library/CoreServices/loginwindow.app/Contents/MacOS/loginwindow: Login Window Application Started I have also tried to boot from CD but this comes up with an error telling me I have to restart my mac... Anyone any ideas ? Thanks for your time in advance.
