No, I'm not using the igpu, I am using the dedicated card, and where did I ever say I was using a laptop? But yes, I am on a Macbook Pro. CPU mining actually generates more heat than GPU. CPU mining gets me like 190F (around 90c) and gpu only heats it up to like 160F (like 75C)
and once you get that gpu pinned it will make alot more heat. try being a little less rude, makes you look like a idiot when you dont know what your talking about.
