How to build your own iMac Pro [Successful Build/Extended Guide]

@kgp
Why does "iMac Pro (i386)" appear in your "Ioreg" in the lower left corner?
My system is "BRUMSUMSEL (x86_64)".

Edit the "AppleGraphicsPowerManagement.kext" directly. Take a look at the "info.plist", go to IOKitPersonalities / AGPM / Machines / Mac-7BA5B2D9E42DDD94 / and remove all entries. Set your own "VendorXXXXDeviceXXX" with your desired entries.

But what you show is the AGPM Enabler for CP00, which works OoB without any kext..

The answer is that the above screenshot has been taken from IOREGExplorer v2.1. If I use IOREGExplorer v3.0.2 (14), I get the same result like you:

BTW.. can you attach your dAGPM.kext for the Vega, thus I can directly implement all necessary settings for Nvidia?

@apfelnico, please see update in post #8440

There it is involved. Look at the original ioreg from the iMac Pro. There you see two entries. Vega56 and Vega64.

ohhh I see... so could you upload your dAGPM.kext that I can adopt it to my system? The original one is not very intuitive..

It's the same, but I do not use it. I had edited the Kext, then no entry was displayed on "machine". In my graphics card, unlike the real iMac Pro also no AGPM is displayed. Somewhere else an "AGPM enabled" must be used.
Editing "AppleGraphicsPowerManagement.kext" is only half the battle.

o.k. I guess I just did it myself:

Although I don't know how to verify control-id, heuristic ID, max-power-state and min-power-state. Looks like you can put there whatever you want... even typos or whatever will appear as implemented ...

@flmmkr, can you live with that?
