Gday i tried to upgrade my 1.83gz 15"macbook pro to OSX 10.4.8 and there was an error in installation. My computer restarted but then tells me to shut down as there is a Panic kernel. Iv been told this is to do with the driver? I did an Apple hardware test and it came up with error code: 4MOT/1/40000002 : Left_middle_front ???? Can anyone help me?
