Hello. I have essentially the same specs as your Designare system (except Vega 56 vs your 64). I've been running this as a hackintosh for a while. It's pretty solid, but I think your method looks more desirable. My question, is if I redo my system with your method would I gain anything with going with Catalina or is Mojave the better (more stable) Designare/i9 setup? Thanks.
