I just started playing Minecraft on my new MacBook Air (fully maxed out; 2.13ghz, 4GB ram, and 250GB drive). When ever I run it though, the GPU's ram goes to the max, the fans kick up to 6000+ rpms, and the temps get up to 170-180 degrees Fahrenheit. So my question is, will this mess up my Mac over time? Should I be concerned? I want this Mac to last as long as possible, so... What do you all think? Thanks guys!
