Hello!
I'm trying to permanently disable the dGPU (NVidia GT 750M) in my late-2013 MacBook Pro Retina (A1398 820-3787-A). I can get the system to boot up using the nvram variable "fa4ce28d-b62f-4c99-9cc3-6815686e30f9:gpu-power-prefs=%01%00%00%00", and can prevent the OS from switching to the dGPU via a handful of different methods (e.g. via OpenCore + WhatEverGreen or spoofing the device properties), but the discrete chip seems to stay powered up and cause the machine to overheat. I'm hoping to accomplish something similar to this hardware modification for a 2011 MBP:...
