Hi. I have had a look through the forums but can't find anything to answer my problem, maybe someone can help. I have a Power Mac G4 1.5 Ghz Procesor. 2 GB Ram. 500 DD. I was running 10.2.8 and went to the apple store and bought Leopard New version 10.5.6 which installed with no probs, as I am doing a software update a black screen slowly comes down and says I have to reboot. In the "Inform Apple" section is shows " Darwin Kernel ecv2sd" I am now loading the Software back in again and hooking up a time macine before I do anything else. Is there something I have missed!!. Thanks for any advice from you guys who have more experience in this area.
