[SCRIPT] fr34k's macOS-eGPU.sh - one script, all solutions, fully automated  

@ojs48,

first let me ask: what is the most recent OS you had installed on your Mac?
2: Did it ever work at some point and you only updated the system to a security fix version?
3: Have you tried 10.13.3?
4: what happens when the cursor can be seen and you log out?
5: You don’t seem to have CUDA installed, but asking anyway: do you need it for number crunching or image displaying? If the former: is your program able to run calcs on the gpu?

Yesterday, I’ve also tried to reuse my High Sierra Partition and was greeted with crashing System Preferences. Don’t yet know what that’s about.

@fr34k, 

To answer your few questions

1. This is a brand new setup and I have never had gotten it to a working state

2. I have not tried 13.3 my install was a 13.6 version 

3. If I log out, both external and internal screen go blank with only cursor showing.

4. I am using this mostly for image display so I don’t know if I should have CUDA install

5. Based on this post https://egpu.io/forums/postid/101470/  It seems like the NVIDIA drivers certification have all been expired and fixes have not worked for eGPU setups.  This may be the end of the road for all NVIDIA eGPU users.  Do you think there’s anyway around that?

Thank you again for your responses.

I'm trying to track down the source, but I managed to find someone with the same drivers (Web Driver 387.10.10.40.140/CUDA Driver 418.163, I believe) with an updated certificate. Apparently if you ask the right support person at NVIDIA, they can provide you with an updated copy. I'm not sure it's kosher for me to post a dropbox link, but hopefully it will be widely available soon, if it's not already.

I was able to remove the expired drivers, install the updated drivers, then run PurgeWrangler (wich has changed its name to Kryptonite), which then patched the new, already installed driver without trying to download another copy.

Everything is back up and running on Cylinder Mac Pros running 10.13.6, High Sierra, using an eGPU over a Thunderbolt 2 to Thunderbolt 3 adapter. We're using them as C4D/Octane animation stations.

I hope that helps.

@frank, Posting a dropbox link to the updated drivers is perfect. Thank you!

I want to make sure that's a legit move before I do it. And I'm not 100% sure it's safe code to run, based on where I got it, so don't want to spread it around just yet.

There has been some good discussion over on Tonymac86 and I'm guessing they will have a legit link ASAP.
