Hello to all Has anybody experienced any freezing while gaming in fullscreen? I have this issue constantly with civilization V and sometimes with borderlands 2 while trying to exit to the menu. Sometimes i can move the mouse and the rests remain frozen sometimes not. If i choose to play them in window mode everything runs fine. I have an iMac 27" 8gb 2.9ghz late 2012. As am i a bit new to mac community, first mac ever after almost 15 years using windows, is there something to do apart from cmd+opt+shift+esc when this happens? Usually i am force to hard reset my mac but i don't thing this would be the appropriate solution. Does it seem like a hardware problem? i have also tried batman arkam asylum and it runs pretty smoothly.
