I am sick of this frickin kernel_task process acting up and it overheating. My ibook ran WoW better then this PoS. I know its not designed to game, but what is the point of having a 1.6ghz C2D if I cant use it? Might have well stuck with my G4. I dont even get a core shut down according to activity monitor, I just get kernel_task hoging up the cpu. I have owned this computer for about 5 months do you think apple will let me exchange it for a macbook? I mean it does not perform as advertised. I have been using apple for years but this is the biggest pile of crap I have ever used, windows or mac. Is ask for an exchange out of the question? And no nothing is wrong with it from what I have read it happens to everyone.
