I can't seem to find anyone else posting about this specific issue so perhaps I'm just ignorant on the subject or it's happening to a small group.

I'm running a iMacPro1,1 connected to a AKiTiO Node Pro via Thunderbolt 3 loaded with: NVIDIA GTX 1080 Ti.

I'm running 10.13.4 and updated Nvidia Drivers to: 387.

OS does not recognize the video card. It sees the Node Pro via Thunderbolt but no card.

Any help is appreciated.
This is an interesting post. Sorry I can't help but I am considering an eGPU so I'm going to watch this thread.

What is your mainboard? Is Thunderbolt 3 working properly without the eGPU?
Hi Bob, I'm using an iMac Pro (couldn't tell you the motherboard specs beyond what is online). The internal graphics card is a "Radeon Pro Vega 64". Thunderbolt is working great in regards to my external hard drives, and even sees the eGPU enclosure, just not the card itself. I'm going to assume it's a communications issue with 10.13.4 and Nvidia, it certainly has broken the ability to use eGPU on my end as it was working perfectly under 10.13.3.
