What graphics card do you have?

Have you connected it properly to the pcie power cables?

What does the system information say about graphics cards and thunderbolt?

It is 1080, and I have connect the proper power cable. Razer Core can be detected but the graphics card cannot.

The way I got around that issue was to download the driver first (I have MBP late 2015 running with Razer Core and 1080 Ti).  It sounds odd, but it was necessary to have the web driver in order for Goalque's script to run in automate mode.  Then the script will download the latest driver again - restart and it should work.

cd ~/Desktop && curl -o automate-eGPU.sh   https://raw.githubusercontent.com/goalque/automate-eGPU/master/automate-eGPU.sh   && chmod +x automate-eGPU.sh && sudo ./automate-eGPU.sh

I then ran the -a option, but it indicated everything was up to date.

sudo ./automate-eGPU.sh -a

When I have this web driver and run Goalque's script, it still shows that

Get a Node or Node Lite. Thunder3 and Razer Core are not macOS compatible boxes.

I can use external monitor by Razer Core but when I run Dota2 it still at a very low fps, could you tell me why?

It seems like external monitor still using Graphics 540.

You downloaded and installed this driver without the script first?
