I was able to install Open Core and Catalina just fine. But for whatever reason, I cannot get my AMD 5700 XT to work in Catalina. It is a flashed card and it will allow me to boot into High Sierra and Mojave. It will NOT however, allow me to even so much as boot into Catalina. Anytime I try to boot using the AMD 5700 RX, it puts me through an infinite reboot cycle. Here's the error report. I'm basically at the end of my rope with this Mac. It's pretty much over unless I can resolve this.
