[Guide] Intel Framebuffer patching using WhateverGreen

[pastrychef]

Which ID if I want to use both HD530 and Nvidia discrete GPU ?

If you have an Nvidia dGPU, the HD 530 should be headless. Therefore, use 19120001.

Edited my previous post...

I mean one display connected to iGPU and the other to dGPU.

Edited my previous post...

I've never seen anyone try to do this, but I assume that ig-platform-id should be 19120000 in this case...

No Macs have a configuration like this that I'm aware of, so I don't know what you should expect. Why not connect both your monitors to your dGPU? Performance should be far superior too.

how to setting FBAlternatePWMIncrement1/2 bit？

Thanks pastrychef,
I may be wrong, but I thought it was a good idea that the power of my GTX 970 is entirely dedicated to my main display only. And since my secondary display is only used for some Finder windows and Apps tool panels, the iGPU is sufficient...
Do you think this is a false good idea?

In my opinion, no. I always feel that it's best to try and keep things as close to the way Apple intended to be better. On real Macs with dGPU, IGPU are configured to be headless/connectorless and that's the way I prefer to go.

I don't think connecting a second display to your GTX 970 for just some Finder windows would cause much if any impact on performance of the GTX 970.

OK, thank you.
Maybe I'll do some tests and report back ...

 

[RehabMan]

Can you explain this in more detail? Are there built in ig-platform-id's specifically for running in headless mode?

The ones with no connectors.
Used by Apple for Macs which use IGPU only for quicksync (all displays/ports attached to DGPU).

Please try this EFI. RehabMan and headkaze confirmed that WhateverGreen may not be doing the GFX0 to IGPU rename properly and I added it to this config.plist.

Thanks Pastrychef, but unfortunately this does not help either.

I am thinking of getting the MSI Gaming Radeon RX560 4GB GDDR5 video card to use with my hardware. Do you think I will have any problems with this video card? Also, can you advise me of any special settings in plist or kexts needed for this video card, or at least direct me to where I can find this info.

Any assistance would be greatly appreciated.

I really don't understand why IGPU is not working for you. HD 530 is supported in macOS...

I just plugged in my RX 560 in my Skylake system and it worked. I already had Lilu and WhateverGreen installed prior to getting the card.
