@alex_dubinin You should be connecting via the barrel plug to the Thunder2 as well as the RX580’s power pins. The PCIe slot alone cannot provide power. So arrangement would be PSU to Thunder2 and PSU to RX580.

@mac_editor I think the problem is that I used this thing instead of the barrel plug, I thought it would be the same but apparently that’s where I got it wrong?

@mac_editor I finally managed to get it working. Got a proper barrel plug as described in the correspondent post. Everything works like a charm, except now I have a weird problem with the PSU interfering with my audio card and causing an extremely irritating noise. But that's a whole different story, the eGPU itself works!
I was so satisfied to see my game on my '14 MBP performing at maxed out ultra settings with a 60 FPS rate.
Thank you so much for your help!

At work I'm using a iMac Pro 18core system with 2 1080ti's.  10.13.6.   

I'm randomly getting system freezes then reboots.  I can reproduce it 100% of the time when I go into the display preferences or screensaver preferences.  Any ideas as to why this is happening or how I can remedy this?  I have this script installed on other Macs and I don't have this issue.  I'm not sure if anyone else has experienced this.

MBP Late 2016, 2.9 MBP 2018, 2017 iMac, Mac Mini.
