Hello All, Are these games playable on my machine? I honestly don't know much about hardware. I checked the minimum Mac system requirements for Diablo 3 on Blizzard's site, and it looks like the game requires a dedicated graphics card. My system specs: 2.4 GHz Intel Core i5 8 GB 1600 MHz DDR3 Intel Iris OSX 10.9.4 I called AppleCare to see if there is a model # associated with the integrated graphics chip, but they weren't able to tell me anything with any certainty other than "Intel Iris." Re: Diablo 3 If Diablo III won't run on my system, I'll just get it for xbox one when it releases next week. But I'd prefer to play it on my rMBP if possible. Re: Dungeon Defenders I purchased this game earlier this summer, and it just doesn't run. I can't even control the pointer accurately on the menu screen and the sound is very choppy. However, I've read that people have been playing this game on older versions of rMBP 13". So I'm a bit confused.
