Hey everyone, I've been trying to get my eGPU set up for about a month on and off now and haven't had any luck. I have a Late 2013 (trash can) Mac Pro running El Capitan 10.11.5 (15F34). I have a Corsair 1000W PSU powering my MSI GTX 980 ti that is plugged directly into my Akito that is being powered by a molex - barrel plug from the PSU. My end goal is to use this eGPU to run Octane Render in Cinema 4D. At first I followed this tutorial posted on the Octane Mac+eGPU Forum. I followed this since the guy has a Mac Pro trash can as well and his end goal was to use for Octane. No luck, my Mac would never start up with the eGPU connected, it wouldn't even get to the start up chime. I then messed around with plugging it in a certain times during startup or turning the Mac and eGPU on at the same time but again, no luck. I thought it must be me making a silly software mistake b/c I don't have much knowledge of this so when I came across the goalque script I thought I was in the clear. No luck with that either. I followed all instructions and still get the same results as before. Until recently my Mac would never even get through the startup while the eGPU was connected. The other day I bought an Apple TBolt 2 cable to use instead of the stock one that came with the Akito and my Mac would get past the startup and I could log in. Instead of seeing my NVIDIA 980ti below my two AMD's under graphics/displays in system report I would see this AMD Radeon HD 8xxx I never really understood this and could not find any information about it online. I've restarted my Mac from backups and the AMD Radeon HD 8xxx does not appear anymore. Whenever I install the drivers and edit the kext files or use the goalque script this AMD Radeon HD 8xxx appears when the eGPU is connected. Any insight anyone has into this would be greatly appreciated! I will gladly provide additional information to anyone that needs it. Thanks, Luke
