@CaseySJ, THX for your input, as always, it is appreciated!
I had sort of resolved to do something like what you proposed already, trying each SMBIOS for myself and comparing results.
Just a few questions:

1. Should I disable IGPU when using iMac Pro?
2. I'm assuming I'll be using a headless config on the iMac19 SMBIOS correct?
3. Would you mind uploading a post-install working config.plist (sans the SMBIOS and RTVariables)? As I mentioned in my first post, only have my installer flash drive, but no access to my hacks right now, so a working config is the only thing keeping me from starting the fun :) Otherwise I'll try and manually edit one of my older desktop configs to at least boot the thing and install Mojave.

Thanks!
To answer your questions:
  1. In general, yes we should disable IGPU when using iMacPro 1,1.
  2. Yes again. Headless platform ID 0x3E980003 when using iMac19,1 with a discrete GPU.
  3. If you search this thread for posts by me, you'll find a fair number of user config.plist files that may be of help. I've stated previously (which means I'm not singling you out!) that I don't upload my config.plist or EFI folder because that defeats the purpose of the build guide.

Hey @CaseySJ

I know this is off topic, but I didn't want to barge in and create a sub problem in your thread again, so, when you have some free time to spend, could you have a look over here?
Done! :)

O sorry, didn't know that :) I'll manually edit one of my existing configs to at least get to boot Mojave and download Catalina. Once I'm somewhat up and running I'll follow the guide to create the proper config :)

Thanks again!

I'm on Catalina now the only thing that's not working is sleep the PC instantly wakes up. Anything else perfect.
What can it be some advice?

  • In System Preferences --> Energy Saver, the option "Wake for Network Access" or "Wake for WiFi Network Access" should be disabled.
  • In System Preferences --> Energy Saver, the option "Enable Power Nap..." should also be disabled.
  • In BIOS, wake for network access should also be disabled.
  • It seems you're using Apple Magic Keyboard via Bluetooth.
    • If so, try this experiment:
      • Power off the Magic Keyboard.
      • Then use your mouse to put computer to sleep (Apple Menu --> Sleep).
      • Does it stay asleep?

If you haven't already, check the actual USB3.0 connector attached to the motherboard. On more than one occasion I've seen the cable come loose from one of the ends, causing one of the ports to not work properly. Make sure the connector is firmly seated with all pins making contact. Sometimes I've seen the connector get pulled by the cable routing or the heavy wires of the connectors putting strain on the port itself.

Also, is this plug connected to 2 thick wires? Or one? (most cases usually have 1 wire per USB3 port)
This plug comes with 2 thick wires.
