My MacBook 1.83GHz has started with the processor buzz. I've seen a lot of MBP owners report this, but no MB owners. I'm certain it's the processor because installing CHUD and disabling a processor core makes the noise vanish. Additionally, and this is my favored solution, I can run Photo Booth in the background and that also kills the noise. There's also a utility called QuietMBP I found written by a guy with the problem, and that works, but often makes the CPU fan spin-up. What I wanted to ask is what to do about the problem. Am I right in thinking Apple won't do a thing about it (my MacBook is six months old)? Are there any other solutions I might have missed?
