iMac Pro + High Sierra 10.13.2 (build 17C2120), nVidia web drivers incompatible 🙁

Hi all,

I am the proud owner of a new iMac Pro. I'm trying to get my eGPU working with it, but it seems that High Sierra has a new build number (17C2120) that doesn't seem to have a corresponding vNvidia web driver. It's strange because I restored my system from a backup (taken from an "amateur" iMac ?!) which had a working build. Was a migration rather than Time Machine style restore, in case that makes a difference.

Does anyone know how I can resolve this issue? Does the webdriver really have to match the build, and if not any idea how to fool it otherwise?

Thanks in advance for help.

(N.B. for those curious about iMac Pro's graphics performance, I did some quick benchmarks using Unigene Heaven. 955 was the score at 4k resolution, everything maxed out, and 1933 on 1600*900. Nowhere near as good as my 1080TI via eGPU which was hooked up via TB2->TB3 adapter on my Late 2014 iMac, which scored something like 2600 in the same test).

Hey,

You can try this script for drivers installation -  https://github.com/vulgo/webdriver.sh

After installing drivers activator, edit NVDAEGPUSupport.kext/Info.plist - find <key>NVDARequiredOS</key><string>17C88</string> and change to <string>17C2120</string>

Then run in Terminal: sudo touch /System/Library/Extensions/ && sudo touch /Library/Extensions/ && sudo kextcache -u /

That is not dead which can eternal lie, And with strange aeons even death may die.

Hi devild, thanks so much for trying to help. Unfortunately I'm still a bit stuck. At this point, I don't have the nVidia drivers installed at all. Here's the situation:

  • Before I did anything else I tried your exact suggestions. However after the kextcache part ran, nothing seemed to happen after that. The nVidia webdriver GUI still didn't let me switch from OSX to nVidia, and rebooting made no difference.
  • I the uninstalled my existing webdriver which was probably a mistake because now I can't reinstall it at all.
  • If I try to run the webdriver installer package it says I can't because the package isn't compatible with this build
  • I can use your proposed script with this command ./webdriver.sh -u https://images.nvidia.com/mac/pkg/378/WebDriver-378.10.10.10.25.103.pkg and it appears to install and completes successfully, but nothing happens after that.
  • I don't have this file any moreNVDAEGPUSupport.kext/Info.plist, I think I need to install the eGPUsupport package but I can't because it fails because of no webdrivers.

Could you please help me to start from scratch?

Fantastic, that worked! Thanks so much.

The only remaining issue is that I have to use the workaround "plug in the TB3 cable once logged in, then log out once recognised in System Report, then log in again". I had exactly the same issue, as have others, with my Late 2014 iMac 5K.

I don't suppose you know how to get it to work without the above, so that I can leave plugged in and reboot at will any time?

Thanks again so much for your help. I will post an implementation guide summarising the instructions above for the benefit of others using iMac Pro.

New Macs typically have a different Mac OS build number than the general release. 10.13.3 and on should be a smoother ride for Nvidia web driver installation.

I have the same issue on my MacBook Pro and I would also like to know how I can just leave it plugged in. 

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

If you close egpu box in power switch, is that works?

@rowl3y if you have a 2008 Mac Pro, this Nvidia eGPU workaround is not applicable.
