I use an iMac... I sometimes play minecraft, but it gets about 100 fps without any mods, and I can run shaders on with about 15 fps... I don't nomally use my mac for gaming, it is mostly used for graphic design. I can keep photoshop, illustrator, and after effects open at once with no lag. Whatsoever. Now,I am not gonna go hate on PC owners, because I was once a PC owner... I find myself enjoying macs more. Every one is entitled to their own opinion... Enjoy your machine
