ok here it goes. i have a black mb w/ 2gb ram and i am on #2 due to the "whine" coming from the left corner of the machine. i dont know about anyone else but i called apple and they acted like i was crazy. i asked them if they read the forums and again, they acted like i was crazy. well, i have had it. this is a week 27 machine and as new as they come. just like previous posts when unplugged the "whine" goes away and also when running photo booth. my dilema is this, should i switch to a macbook pro? have they finally fixed the "mooing" and "whining" on those? from what i am reading those issues are gone on the macbook pro side. advice please?? would you like cheese with your whine?
