How to extend the iMac Pro to X99 [Successful Build/Extended Guide]

[kgp]

Also if i boot without Nvidia Graphics (i.e. nv_disable=1 or disable the kexts from loading i.e. from clover boot menu)

i get Black screen with

IOConsoleUsers: time(0) 0->0, lin 0, llk 1,
IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0

blinking in the top left corner of the screen. That's my experience with getting macOS High Sierra working on my hardware.

Did you try it with NVWebDriverLibValFix.kext, NvidiaGraphicsFixup.kext v1.1.3, and Lilu.kext v1.1.7 in /EFI/CLOVER/kexts/Other/ ? See post#575 and post#579

However I recently have been told that NvidiaGraphisFixup.kext already implements and applies both the AGDPfix and NVWebDriverLibValFix.kext fix. However, you say that only with NvidiaGraphisFixup.kext and Lilu.kext in the EFI-Folder you are not able to fix the black screen issue. You indeed need NVWebDriverLibValFix.kext in addition?

Any other additional patches to that?

after a couple of failures with AGDPfix I gave up and stopped to using it at all, in my first combination I have only AGDPfix and it was ok with earlier betas dp... but not with the final webdrivers, I have tried to use only the lilu.kext and fixup.kext but no luck at all, first I have fixed it with installing the LibValFix.kext to S/E/ but after a few reinstallation of the system I have forgot and got the black screen again, because I had a fully functional 10.12 on the other drive with its own efi I decided to try to put this LibValFix to the 10.13 efi so I have side loaded it using my booted 10.12 after reboot got the picture back

so at the end:

all thee kexts in EFI partition kexts/other
no other fixes used
so the system itself stays pure and unmodified
at the end I have add the emuvariableuefi-64.efi to the efi drivers but it works good long before it and in my case it has nothing to do with the graphic configuration, I have added this to get fully working nvram, still have some hope there is some way to modify bios to get native write to nvram but this is a different story

Thanks man! And you used NvidiaGraphicsFixup.kext v1.1.3, and Lilu.kext v1.1.7, correct? The -lilubeta boot flag is obsolete now with Lilu.kext v1.1.7 and High Sierra 10.13, correct?

How can I send you my efi ? I think this will be the best idea but I am not sure if it's ok to upload it here ?
I don't know how to check the kext version so it will be easier for both of us I think
if you wan't me to upload it here, thats fine with me

a.) you can upload your EFI-Folder, no problem, just delete before your SMBIOS credentials! i.e. Board Serial Number, Serial Number and SmUUID...

b.) To check the kext version: right mouse-click on the kext.file -> "Get info"

STRANGE ISSUE: Anyone else have this?

I am able to get High Sierra all the way through the loading and installation process (thanks to KGP) and rebooting 2 times, however, on the final reboot after booting from the EFI on my system disk (instead of the USB) I do not see the "Install on drive xxxx" option. It is gone, thereby not letting me finish the installation. I have tried all the boot options that come up, and it either restarts the install from the beginning, or tries to boot the computer. Any help?

in the last step of the macOS installation process you just have to boot with the EFI on your System Disk (BIOS boot menu) the "High Sierra Partition" (Clover Boot Menu) ... The "Installer Partition already disappeared at this final macOS Installation step" . That's like it should be! Everything as expected Maybe my guide is not clear at this point, but I thought that it might be obvious in any case.. related section in the guide is now modified in any case

my full efi folder attached, there is also one extra kerneltopatch entry helping me a lot with performance so please don't shout on me again as this is my only personal experience and I am not encouraging anyone to use it
there is also my full dsdt patches and everything so anyone who for some stupid reason wan't to run it without even checking it please be aware. Thanks

Thanks but I don't really think this is necessary in my case, I am hackintoshing since 2006 I should be ok

Promised I will not shout

NvidiaGraphicsFixup.kext v1.1.3 and Lilu.kext v1.1.7 confirmed! NVWebDriverLibValFix.kext has v1.0.0...

You should also update CsmVideoDxe-64.efi (you use an old version from 22 Sept. 2017).. All other efi-files are correctly taken from Clover_v2.4k_r4233

You should also remove the zip-files from /EFI/CLOVER/ACPI/patched

And you should not use the xcpm performance fix(wrsmr fix to get CPU max) ⓒ okrasit !!!!

Thanks man!

Ah I see. haha. Strange things happen when working on Hackintosh coding at 1 am. One easily misses the obvious. Thanks!
