Hi, I have searched for this problem allover the net and read everything and tried everything but nothing has worked. I was loading some up-dates and my mac suddenly went to Kernel Panic black screen telling me to re-boot, so I rebooted and now I have the Kernel Panic screen all the time and Im unable to use the Mac. I did the hardware test and found no problem, Ive also tried re-loading the disks. does anyone know what I can do ?. Thanks so much for any help !
