changing the graphics card in macbook pro

Is that true? And if yes, how to do that? I heard that the same EFI setting is responsible for not even showing the integrated GPU to other operating systems than macOS and you have to trick it somehow to think it's macOS. If I disable the discrete GPU from EFI, will macOS think that the integrated GPU is the one installed and will it let me use multiple monitors with it? If you force integrated graphics in GfxCardStatus, Mac OS X (up to Yosemite at least) doesn't allow you to use multiple monitors (even though the built in Iris Pro can do it). The question is basically whether the command mentioned in GfxCardStatus github issue comment here is correct or not, and how to undo it if it doesn't work.Īn answer to this alone is a correct answer, but it'll be awesome if you can also tell me: I'd also want to know how to undo it if needed. I assume this is persistent across multiple reboots. How can I disable the discrete GPU from EFI? I know I can use GfxCardStatus but I read I could have a more permanent solution by changing some EFI flag. I'd like to disable the NVidia GTX 750M GPU on my MacBook Pro 15' (Retina, Mid 2014, Mac OS X 10.10 Yosemite).
