However, if the EFI of the release is applied to the installation of 10.13, the following will be prompted:

HDMI does not work because it is wired to Nvidia card.

I'm not sure in regards of the miniDP. I don't have one with me right now so I was not able to test. You can test with other ig-platform-ids.

If it doesn't work and you really need an external monitor you can use a usb-c to HDMI adapter, which works

@zacmks Wait really? I thought everything is connected to the iGPU and it acts as a passthrough for the dGPU too. Isn't that how the setup is required to be for Optimus to work?

The Nvidia GPU has a muxed setup on Aero, that's why it even work for us on HDMI with proper drivers. By muxed, it means that the switch is done mostly hardware-wise instead of software.

The muxless setup (in contrast with our muxed setup) usually does not work with hackintosh laptops at all.

This means that we are very luck that Nvidia Card works on our laptop (even though it works only on High Sierra due to lack of drivers).

The side effect is that since it's hardware wired. If we don't get the proper drivers, it could make some ports unusable (as far as I could test with my setup).

One more problem I have is that with the 10.13.6 EFI file, I can't install macOS, suggesting the situation in the picture. image

10.14 can work, 10.13 can't work, can't install
