As the title says, is there any way to disable dedicated GPU permanently? I'm the owner of rMBP 15 late 2013, unfortunately my brother persuaded me to buy a macbook with second GPU but I'm a bit disappointed about that decision. Nvidia card switches every time I use MatLab, iPhoto, Parallels, and many others despite the fact of using GfxCardStatus (because they appear on the dependencies list so they force dedicated GPU to turn on and there is nothing to do in this case). Ded GPU heats up my mac significantly, drains A LOT (really A LOT) of battery and it does not give me as much benefits as I thought. It sucks even in not demanding gaming. I don't expect graphic fireworks, especially on newer games, but it holds 60FPS only in old games. I wish I had bought much cheaper mac with Intel HD only because second GPU only irritates me. Every task I do and every game I play the Intel HD Pro would hold perfectly. Any ideas?
