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

[cadriel]

I'm having an issue I'm hoping someone can help out with;

I'm following the guide almost exactly (See below re formatting as APFS);

Haswell-E X99 system. 1080Ti GPU. Asus X99 Pro / USB 3.1 Mobo. Has been running Sierra fine.

I've created a USB 3.0 drive that boots into the installer fine. I have formatted my system partition as APFS and installed a clean copy of Clover, along with my working EFI folder to it.

I go through the 2 initial reboots, and High Sierra seemingly installs fine onto my system drive. However, the third reboot - whereby you should boot off your system drive for the first time hangs at the +++++++.

I haven't been able to get past this step. Anyone encountered and resolved this?

Thanks!

UPDATE:

I've now tried this using an HFS+ formatted drive with the same result. I can install, but it always fails with the final step.

@mimixa Are your bios settings for cpu especially, the same as in the guide ? I know it's a different mobo but it should not be that different .
Also hyper threading is on or off?

Bios 3601 new.

Hi
I used the guide very successfully, really a great help.
Now however, using the Migration Assistant to get my data from 10.12.6 to 10.13, System will not boot after migration anymore.
Anyone with experience what could be the cause?
Are the old NVIDIA drivers from 10.12.6 also migrated and that could cause the trouble?

What happens when I reboot is that the system instantly reboots just before entering desktop.

MB: Asus X99 Deluxe II (bios 1401 unlocked) CPU: Intel i7 6900k GPU: Gigabyte GeForce GTX 980 Ti, G1 Gaming, 6Gb SSD: Samsung 960 Evo 256 Gb RAM: G.SKILL TRIDENTZ 32GB 2X16GB KIT-3200 Case: Fractal Design Define R5 PCGH Edition (all Noctua Fans) PSU: Be Quiet DARK POWER PRO 11 650W

Thanks, Mike

Why don't you just clone your 10.12.6 System Disk by means of Carbon Copy Cloner (CCC), and directly perform the 10.13 macOS High Sierra Update on the latter clone drive? No need for migration in this case! The only thing you have to consider for the latter approach is to copy the working 10.13 EFI-Folder in the empty EFI-partition of your 10.13 clone drive immediately before performing the macOS High Sierra 10.13 Upgrade!

That is probably a good option now that I have my Efi-Folder cleaned up.
The reason I went for a clean install was to have a more stable system. I did not really expect any challenges with the Migration Assistant.
But you are right if no other users have any feedback regarding the migration assistant, I will do exactly what you proposed.
Thanks, Mike

One question regarding you Geekbench results.... I assume those were done with Brummbärs Pmdrv.kext?
I only really get good performance using that kext for the Geekbench for multicore results especially.
But the drawback is that it breaks sleep.... so the choice seems....either good performing system or sleep.
Thanks Mike

Yes with PMDrvr.kext and EIST enabled in BIOS!

Apologies for all the posts, I have tried this so many times and I would love to make some progress...

Recap I have:
MSI X99A SLI Krait
i7-5820K
Gigabyte GTX 980 Ti
Samsung 850 500GB SSD

I have this now (Step D.1 / 13.) :

Then...

Then if I let it go some more it turns into this:
