Planning to also try this on my 2013 nMP and compare to the iMac, seems success on the nMPs is iffy? I can only find one implementation guide. If I only want to use the GPU for rendering and not for display, is there anything to be aware of? I assume I don't need to bypass the dGPUs in this case? Thanks JG

Uninstalled the script, backed up the iMac, just in case. Reset NVRAM. Booted up, installed script once, then 2nd time with -a. Reboot. 980ti reported! Success. Did not need to reinstall OSX after all. Now to get this working with Octane Render...

Hi All, Thanks to all for the knowledge here, it's been great reading. Set up my first eGPU today, a an EVGA Hybrid 980ti connected to a Highpoint TB2 mounted inside a mini ITX case with PSU. Was running 10.10.1 and ran the scripts, GPU showed up as Nvidia Device, then figured out I needed to update OS to have it show as a 980ti. So I am now on 10.10.5. Ran the script a 2nd time, it downloaded drives (for the 2nd time) even though it doesn't find a mac board ID. Installed drivers, rebooted... and it reboots in a loop. Reboot, grey screen saying press any key, reboot, grey screen etc etc. What would be the trouble here? I assume my components are okay as the eGPU was detected under 10.10.1, just not as the correct exact card (Octane Bench would not see it). Do I need to un-install the script? Run again? Going to the Nvidia panel, it detects other drives again... which ones to use? Ones from script or ones from Nvidia? I get this message box saying the default OSX graphics driver is being used iMac mid 2011 Attached screen grab of Nvidia panel Is this the thing where I need an external display connected for this to start up correctly? I remember reading that but now can't find the source for that info.
