I downloaded the combo upgrade file from MacFixit and installed it. It required that I undergo a lengthy download and upgrade procedure. At the end, I lost my capability. I installed the combo upgrade to my PowerBook G4 15" Power PC G4 (1.1), 1.5 GHz, 1 GB Memory, Boot ROM Version 4.8.4f1 which had great Bluetooth connectivity. Afterwards, it reports "Bluetooth Not Available" in faded type. I note that I'm not the only person who experienced this result. What are my options now? Am I forever without bluetooth, or is there some way for me to revert to what I had before? -- Nick Since the Internet has no walls or fences, who needs Windows or Gates?
