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

[Lorengrin]

Your Vega suddenly shows up in Slot-6 under PCI, because apparently the entire SSDT, or at least the GPU and HDAU part fails to load during boot! Please fix!

My guess: As I explicitly state in my guide, method DTPG has been outsourced from the new Nvidia and Vega system SSDTs. To properly run the new SSDT-X299-ImacPro-Vega.aml, you also need SSDT-DTPG.aml in /EFI/Clover/ACPI/patched/, as explicitly detailed in my guide.

EDIT: I just removed again method PWR from the XHCI PCI device implementation, as apparently it prevents the successful implementation of the system SSDTs during boot. SSDT-X299-iMacPro-Vega.aml and SSDT-X299-iMacPro-Nvidia.aml once more reloaded in post 1 of this thread!

The new SSDT-X299-ImacPro-Vega.aml works fine again, Vega is now in slot 1. I make a modification to remove the 10GIGA network card and to place the Broadcom BCM94360CD WIFI in slot 6, if it is not done, this causes KP if it is installed in slot 6.

Still using THCAdjustReset.kext? The problem now is not related with memory allocation errors and also not with "above 4G decoding"! Are you using any XHC USB kext?

Else you should revise your BIOS settings..

Hey I´m not using a THCAdjustReset.kext and no XHC USB Kext! The only Kexts in my EFI are "AGPMEnabler.kext", "FakeSMC.kext", "IntelMausiEthernet.kext" and TSCAdjustReset.kext".
Am I missing something there?

I adopted the BIOS settings you recommended for the ASUS mobo!

Hi all. I have followed this guide up and till D4.8 and D4.9 - The installer errors with the attached screen shot while at the Installing progress bar and stops at around 11 minutes remaining. I am wondering if this is because EFI folder is not yet on the drive (I can't take the drive out easily and am hoping to do this after a successful install but can't get further than attached).

Perhaps I can download 10.13/10.13.1 or 10.13.2 installer and see if it goes through and the use update to get to 10.13.6?

Thanks

Hi Kgp,

Hope you are well.

Is there some new setting to be added for the i9- 7920X? I saw something for other processors while catching up on missed posts.I cant seem to find it again.

Im on the new 10.13.6 release with your updated folder.

Thanks.

Okay, kgp, I am trying to get this to work. I attempted a re-compile of your aml file and I replaced the Airport slot 3 with as much as I could with my slot 5 code (it compiled with no errors). I have been working on this for quite a while.....with no luck.

When I run a report, I don't see the Wireless in my PCI report.

Can you (or anyone) take a look at my adjusted aml file to see if you can see anything that could fix this? I have been working on this for quite a while with no success......I have uploaded my ioreg file....

That’s what my UPS shows, the screen isn’t even plugged on the UPS.

BTW, my Bluetooth usb dongle works perfectly, I disabled the USB port attached to the built-in BT. haven’t tested with the Magic Trackpad as I don’t have it here.
Do you know if there’s a way to have both BT adapter working at the same time? So I would have the trackpad linked with the Broadcom BT card, and the headset with the USB dongle.

Found plenty of ways o switch between the two, but only one works at a time.

Hello @jyavenard, I got a very basic, probably stupid question. I got a Bluetooth USB Dongle to see if it worked better than my built in adapter but I can't activate it, do you mind pointing me in the right direction? I tried the Bluetooth Explorer thing, but its not working for me.

I couldn't switch between adapters either, so I simply disabled my onboard BT adapter in BIOS. After that, the USB dongle worked.

If you use "SL0C" in your ssdt, you are saying that you have your card in "slot3", I have not been able to check your ioreg because it is corrupt, I recommend that you compress it in .zip. Find the correct entry for your card and correct SL0C for the correct entry, greetings.
