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 /

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?

After installing drivers with your command ( ./webdriver.sh -u  https://images.nvidia.com/mac/pkg/378/WebDriver-378.10.10.10.25.103.pkg  ), try to install this version of activator.

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. 

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

Here is a video of what it does .. 

I don't know what else I can do 

i get this error .. 

Kext with invalid signatured (-67062) allowed: <OSKext 0x7fdfd82441e0 [0x7fff8681a980]> { URL = "LegacyUSBInjector.kext/ -- file:///Library/Extensions/", ID = "com.parrotgeek.LegacyUSBInjector" }

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

Did you have to turn off Startup Security on your iMac Pro or was leaving it at it's default 'Full Security' work just fine?

Hi Paul, no I didn't need to turn anything off (apart from SIP, as per standard installation procedure).

Hi @devild, I just installed the MacOS HS update for the spectre patch, now my build is 17C2205. Could you help me with another build or tell me which files to modify and how?

Many thanks for your help.

Hey @dangerous25, 

Update Nvidia drivers with script (./webdriver.sh -u https://images.nvidia.com/mac/pkg/378/WebDriver-378.10.10.10.25.104.pkg )

Open Terminal and edit Info.plist in NVDAEGPUSupport.kext:

sudo nano /Library/Extensions/NVDAEGPUSupport.kext/Contents/Info.plist

Change NVDARequiredOS to 17C2205.

Save changes and close the file (CTRL+X - Y -Enter).

Run next command:

sudo touch /Library/Extensions/ && sudo touch /System/Library/Extensions/ && sudo kextcache -u /

Reboot.

Any chance you make break this down a bit more step by step. I am not a regular Terminal user, only when needed. I'm having the same issue. iMac Pro with eGPU setup. 

@dangerous25,@devild 

Hey all. I've been at this for several hours now. No luck. I'm stuck at the very start. I'm trying to download the web drivers. I can't just install the drivers because they aren't compatible with 10.13.2 and I'm trying to follow your terminal script however I keep getting a "fork: Resource temporarily unavailable" error. Any help is greatly appreciated. Also, earlier today I tried installing Beta 4 of 10.13.3 hoping it would just work, but no luck. I'm back on 10.13.2 for now. I'm keeping at this so anything you can tell me would be a huge help. 

Good one!

Could you run the below and paste the output?

ulimit -a
sysctl -a | grep maxproc

As a quick attempt to fix (all risk is yours!) try doubling the values from the last command where AAAA and BBBB are double what you got before (mine were 8512 and 5674 respectively)

sysctl -w kern.maxproc=AAAA
sysctl -w kern.maxprocperuid=BBBB

Then try to install the drivers again. If that works, of course it doesn't explain what is using up all your system resources...

So I've made it almost to the end. However when I try this "

Run next command:

I get the following:

Any idea what is wrong? 

@jrock, nothing is wrong. All is OK.

I noticed that there's both version *.105 and *.106 of the web drivers, and 106 seems to be targeting build 17C2205. Should we be still using *.104 with our iMac Pro's or try with 106?

(The 106 link:  https://images.nvidia.com/mac/pkg/378/WebDriver-378.10.10.10.25.106.pkg )

@paul_colton, if new drivers are available and working w/o the script with 17C2205, use them. Theoretically, they should have the same number as 104, so only NVDAEGPUSupport.kext editing is required.

Thanks everyone for the help. It's up and running. For fun I did a side/side comparison. Pretty interesting results. Honestly I felt the eGPU would make a bit more difference.

@JROCK: Glad to hear you are back in the game! May I know how you got around the "fork" error?

@JROCK:

Nice one on getting your set up working!

I have a similar configuration with the iMac Pro, my egpu box is a Netstor thunderbolt series with a TitanX 12GB Maxwell card in it.

Installed the latest webdrivers (pkg 106) and the Nvidia egpu Support app from here, but no dice.

Do I need to edit something? could you give details on how you got it to work and recognize the extra GPU?

Thanks for any help!

Hey all. Here is the pkg file for 17C2205 for easy use w/o Terminal editing 😉

@devild:

Wow! nice, thank you so much.Works like a charm!

Found out I need to plug the egpu at login stage otherwise it gets stock on a black screen.

I m going to try with a second box connected :0 

Just live with it. Unless you have to use something CUDA, your VEGA 56 or 64 will hold on pretty well in 2 years. I believe by that time NV will fix the driver.

@devild, any chance of getting similar scripts or ktext update for the latest iMac Pro HS release? I've tried installing the 17D2102 version with no luck (though I did the plist edit and touch and haven't yet rebooted, but I got a pile of errors on the touch command).

This is for macOS 10.13.3 (17D2104).

I have same iMac pro macOS 10.13.3 (17D2104) 
Could you send me a kext update for this please?? Because i didn't mange to do that without this 
Thank you so much...

Hi,

I also have an iMac Pro with 10.13.3 (17D2104). I tried to follow the instructions to hook up my new egpu case and card but I’m stuck at the webdriver installation like the others here. Supposedly the appropriate driver for my macOS build is 378.10.10.10.25.159 but neither using the installer directly or the webdriver.sh script works. They both say that no matching driver has been found or that my build is not compatible. 

Any idea what the culprit could be? I found this thread and there seems to be some solution for earlier versions but not for this. Any help would be greatly appreciated!

Thank you!
