Hey Marcus, I actually tried this as well but drivers don't seem to be loading on my system.
I'm running Clover Mac 14,2 with a GTX960. I have updated NVDARequireOS tag in the above kext to 16D32 and clover settings are enabled for WebDrivers. System is seeing "Display 7 MB" as my graphics card. My system is based on an XPS 8700 so it does have the Intel integrated graphics, but this was never an issue in the past plus monitor is running off the GFX card.
Any ideas? Not sure how to diagnose.
Edit:
When I run: "sudo kextcache -system-prelinked-kernel"
I get the following error:
Invalid signature -67030 for kext <OSKext 0x7fb4e9313590 [0x7fff90cb3d80]> { URL = "NVDAStartupWeb.kext/ -- file:///System/Library/Extensions/", ID = "com.nvidia.NVDAStartupWeb" }
KernelCache ID: 2CF7D6C1D60FA959A5B55F9FF9B1BE80
Note I have CSR settings which should allow me to do this. Not sure why I'm getting the Invalid signature.
