Help with Late 2015 iMac 5k 27" +Akitio Thunder 2 Nvidia eGPU on High Sierra
This setup worked on Sierra, but I've been testing with High Sierra and it doesn't work.
With 10.12.6 I used automate-eGPU.sh 1.0.1 which resulted in a working although a little flakey system. I believe the script was modified to fix a problem with the 5k iMac, I can't recall the details though.
With 10.13.6 I can't get anything to work at all.
I've tried the macOS-eGPU.sh script but that results in a hang before getting to the desktop. Tried purge-manage, which booted and showed a generic nVidia card was present as an eGPU in system prefs but the nVidia web driver pref pane doesn't see the card at all.
Tried the EFI USB drive option but that didn't work either (kept getting file system not recognised on the stick).
I'm at a loss. Is there anything else I can try?
Look forward to your help.
Hope this is the right subforum to post this Q?
