[SUCCESS] Hackintosh will not boot with iGPU & Vega 64 GPU (running together) with Thunderbolt 3

@jaymonkey & @pastrychef

Hey! Thanks @jaymonkey for the tip about the VGTab Utility. I installed it and changed fan speeds and clock speeds and I thin my Vega 64 is behaving optimally now. Thanks!

One question....is there a way to get H.264 videos to render using @pastrychef 's EFI with the Platform-ID 03001259 and an SMBIOS Product 18,1? Thanks for any help you can provide.

You can set ig-platform-id to anything you like, but how well it will work is questionable.

@patrickfogle,

I assume you mean iMac18,1 ? ... if so then it's not recommended ... iMac18,1 uses a low power 45W 'U' series Kaby Lake CPU, you should really use iMac18,3 SMBIOS which is for a full fat (91W) Kaby Lake CPU and configure the IGPU with Headless PlatformID 0x59120003 using WhatEverGreen :-

ID: 59120003, STOLEN: 0 bytes, FBMEM: 0 bytes, VRAM: 1536 MB, Flags: 0x00001000
TOTAL STOLEN: 1 MB, TOTAL CURSOR: 0 bytes, MAX STOLEN: 1 MB, MAX OVERALL: 1 MB
GPU Name: Intel HD Graphics 630
Model Name(s): iMac18,2 iMac18,3
Camelia: Disabled, Freq: 1388 Hz, FreqMax: 1388 Hz
Mobile: 1, PipeCount: 0, PortCount: 0, FBMemoryCount: 0

Always match SMBIOS based on CPU Type/Generation.

Cheers
Jay

iMac18,3 is best for a Z277 Motherboard? I thought it was iMac 18,1.

I was successful at booting with iMac18,3 SMBIOS and the IGPU with Headless PlatformID 0x59120003 using WhatEverGreen, but I am still unable to render H.264 videos from FCPX. Any suggestions?

@patrickfogle,

Please generate and post PR files :-

And i'll take a look and see if i can spot anything wrong.

@jaymonkey,

Thanks for being willing to check!:

@patrickfogle,

One thing to try would be disabling the following two Clover ACPI fixes :-

• change GFX0 to IGPU
• change PEGP to GFX0

WhatEverGreen should do these renames for you using a more specific method rather than the global search/replace method that Clover uses ... I've seen at least two configurations where using the Clover renames caused issues, so try disabling/deleting them form config.plist, save the changes and reboot ... then check H264 encoding again.

@jaymonkey,

Thanks so much!! I’ll give that a shot...

I’ve also started having a problem shutting down when rebooting. It doesn’t hang on the boot, it hangs on the shutdown. Any clues?

Thanks!

@patrickfogle,

You could try enabling Clovers "Shutdown Fix" and/or the "Halt Enabler", The "Fix Headers" patch can also help :-
