Hey everyone. So I was playing Counter Strike:Source for about 3 hours with my MBP elevated so heat can dissipate and as I was playing the game started lagging (it was running smoothly all night). Then when it became unresponsive on my screen(yet I can see and hear everything other players were doing) and when I would press escape the mac home screen came up but immediately disappeared and it went back to the unresponsive game screen. I had to shut off the mac by holding the power button and since turning i back on its been fine but I was wondering, if it was an overheat issue,is there any damage concerns I should have? or just lay off the games for so many hours in a row? thanks in advance.
