Anyone tried to replace AMD with NVidia

The web drivers are only for Sierra. IIRC some people on the eGPU forums tried anyway and reporting it not working.

Nope it doesn't work, NVIDIA web driver are not able to recognize any card atm

Yep ... I've got a GTX 1070 right here. After 4 hours of tweaks, it's a no-go. Popped the Radeon RX 580 back in, rolled back my system via TimeMachine, and everything works again ...

Even Nvidia-based macbook can not support for AMD-eGPU, say nothing of Nvidia-eGPU, Apple totally disregard Nvidia-related devices, so be it.

We all have known what 's the true-face of Apple!
