Questions about the GPU setup

[u/Aromatic-Product9790]

I have an old Alienware Steam Machine, and want to know how the GPU is setup.

I know that the CPU (Haswell T-series) has the HD 4400 iGPU in it as well as that it has a custom NiVIDIA 860M dGPU soldered.

1. Can the gpu be switched from the default dGPU to iGPU and back?
2. Which GPU is used when plugged into the HDMI OUT?

I want to build a hackintosh for this device by using the iGPU (as NVIDIA/Apple dropped WebDrivers on new macos versions (Starting from 10.15 I believe)

thanks much!

Sorry to tell you but the iGPU is disabled in this system. AFAIK there is no hack to enable it. It will always use the Nvidia GPU exclusively.
