I'd be really grateful. I've been thinking about replacing my broken laptop with a Haswell rMBP 13", but I need to use a certain program that is said to be partially incompatible with Intel HD graphics, but may work with the Iris 5100. Can one of you guys download Resolume Arena 4 http://resolume.com/download/ here (it's free and doesn't carry adware or anything). The things that I hope will work with the Iris 5100 are the Chroma Key Effect and the Advanced Output, where you can warp the image, like here http://i.imgur.com/3jgbf9n.png and here http://i.imgur.com/SFJ28rc.png. My local Apples store wouldn't let my try it out , I hope one of you guys can.
