Not offtopic at all! Dirty hack for sure. The enclosure I bought was a hack, the drivers were a hack, and there was software on top that was a hack as well. But the developer experience was totally awesome… Almost made the constant graphics crashes worth it. Almost.
Can you provide some more details on your eGPU hack for those of us who might want to try our hands on that as well?
There is official support for eGPUs in macOS High Sierra beta.
