2013 nMP + Tesla K40c @ 16Gbps-TB2 (AkiTiO Thunder2) + OS X 10.11.6


Recommended Posts



I am trying to get this eGPU configuration to work with my new Mac Pro. The GPU (Tesla K40c) is installed in the Akitio, and powers on (300W external power supply, 6-pin + 8-pin connectors). After connecting the TB2 cable to the Akitio, I ran goalque's automate-eGPU.sh version 0.9.9. Output:


*** automate-eGPU.sh v0.9.9 - (c) 2016 by Goalque ***

You are running official Nvidia driver.

Do you want to download this driver (y/n)?




I have tried this multiple ways, each after an uninstall, reboot, and a fresh install. The options I've tried:






In all cases, the behavior has been the same. The eGPU is visible under System Report (see attached screen shots). However, since this is a Tesla card, it does not have any video out connections (strictly for GPGPU / CUDA). I do not have an external monitor connected to the eGPU. This appears to cause problems after reboot (main monitor, Apple Thunderbolt) is on, but "dark" (slight blueish glow, but nothing displayed, shortly after the Apple logo appears). 


Also, if I logout, I lose the main display, same features as above.


It looks like the driver really really wants a monitor attached to the eGPU. 


Is anyone aware of a potential fix for this issue?


Any help appreciated
