Hey John, Excellent news ! Happy to hear you were able to resolve the issues surrounding this. It sounds like it was the memory after all as I had sort of thought that it would not have been an issue, as my experience with most 3rd party memory has been problem-free. I have always believed and and appreciated that mac owners have a strong sense of community, it is never been just a group of people with boxes, etc, rather the opposite: passionate creative people who are willing to help each other. And these forums, this one in particular in the past, was very active in this regard. Have a nice day. I believe I sent you my contact info before so if you have a question about anything aside from this board, I will be happy to do my best to help in any way if possible. Have a good day Cheers from Geneva, CH Fred On 09.08.13 03:25, "John Sparks" <jmsparks1 at verizon.net> wrote: >Hello Fred: >Finally success, Leopard is installed on my G4 PowerBook 867 Ghz.
