Using dGPU instead of iGPU (macOS sees both of them) [HELP]

Hello everyone,

I have a Sandy Bridge CPU with Nvidia GT550M as the GPU, I'm using macOS 12 Monterey.

I firstly disabled my dGPU by using the "-wegnoegpu" boot argument in my config.plist, then installed macOS using only the iGPU (Intel HD Graphics 30000).

After the installation, i installed OCLP and installed drivers for my iGPU while my dGPU is still de-activated. After that, i wanted to be able to use my dGPU and used Dortania's Post-Install guide to activate my dGPU and remove the "wegnoegpu" boot argument.

​

macOS (12) succesfully booted after that, and OCLP saw all the needed drivers for my dGPU and i installed them. The problem is, i can't use my dGPU even though my macOS installation sees it (my SMBIOS is for MacBookPro11,5, could this be the problem?). Also there's no option to use dGPU in battery section.
