I have call of duty modern warfare 2 on my mac. I've probably played it about 20 times. EVERY time i play it, I hear the mac making a lot of noise from the inside kind of like something is spinning or something I'm not sure what the loud noise is. Also everything gets super super hot like the actual keys on the laptop and everything. Also I smell a burning kind of smell like plastic or i smell the mac's inner materials easier. Is this bad? is it normal when playing a video game online? is their any sort of way i can test my mac to see if it is damaged or performing fine?
