Mac eGPU help?

I figure I'll throw this out here and see if Iget any bites:

I work on a 2017 iMac running High Sierra. I picked up an Akitio Node and an Geforce GTX 1080 hoping to improve my rendering times but have been bogged in technicalities ever since. The Thunderbolt bus shows the Node, but not the card, and after a couple weeks of banging my head against the wall with various driver updates, hacky terminal commands and assorted other voodoo, that's still where I'm at. Anyone here have any advice?
