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

Sure. BIOS configuration is as detailed in the guide through step E.7. Attached is my EFI.zip. Not sure what's causing the freezes/crashes, so instructions on what I should do to gather bug/crash logs would be appreciated. Absolutely no audio devices, no HDMI audio, no USB audio, nothing. Any advice?

5960X
2x Titan X (Maxwell)
Rampage V Extreme
64GB RAM

EDIT: When I opened Clover Configurator right after logging in, it flashed white indicating I had a notification, but it froze the whole screen. Hard reset didn't help, and when I logged back in macOS reopened the frozen windows and kept them frozen. Had to reboot several times to get it back to normal. Don't know if this is a coincidence since the freezes have happened even when I hadn't opened Clover Configurator. Just thought this might provide a bit more info.

EDIT 2: Now all my stuff is crashing/freezing on login, but if I login as guest everything works fine. It keeps loading the same windows and is crashing before it lets me close them. Screen flashes black very briefly on login. Clearing the nvram also fixes the problem, but the problem comes back.

EDIT 3: Uninstalling and Reinstalling the Nvidia Web Drivers seems to have fixed the login problems (unsure yet if it fixed the white-flash freeze/crash thing). However audio remains broken.

Your EFI-Folder would benefit from a clover update.

Disable nvda_drv=1 bootflag in the config.plist (obsolete)
 
Hey, thanks for the guide once again. I've Updated my X99 10.12.6 to 10.13.4. One problem, and it’s a big one, I cannot access my Windows SSD anymore. I can’t open it’s EFI any which way I try. It doesn’t show up in my BIOS (delete or F12). No way to access via Clover screen. Some how, during update, it’s erased or hidden the Windows’s EFI.

Anyway to fix this with out reinstalling???

Hi, unfortunately a similar thing happened to me once I installed High Sierra on NVME. I can no longer see an SSD with Sierra from the boot option in bios. We have similar hardware and I have a question to ask you. With the playback of all the clips I have continuous video freeze as well as not being able to export h264 to FCPX, depends on the CPU or GPU? I use only one GPU as primary (RX 480, lilu, whatevergreen). I followed this excellent guide without having problems of installation up to power management. Do I still need a video card helper or can I fix this issue without it?
Thank you.

No need for video helper card with Lilu and whatevergreen worked oob with @kgp guide.
 
What about enabling ACPI replacement ALZA -> HDEF in your config.plist?
Ok enabled, no change whatsoever. I have a ASUS Rampage V Extreme Mobo. Should I be using Reltek ALC1150 or VoodooHDA kexts?

Maybe you need to inject an audio ID different from 1? This mainly depends on your onboard sound chip.
 
Hello, I have gone through this guide until the CPU power management section and my problem is I have a CPU water cooling system and another fan which sucks the air into the case and the CPU cooling pushes the air out of my case. my CPU fan is working but my other fan when I boot the system suddenly stops. could anyone help me with this problem?

Oh by the way before that I had a Sierra version of mac and I did not have this problem

I never get to thank you KPG. thank you for your great great post.

Do you use TSCAdjustReset.kext or VoodooTSCSync.kext?
