Problems with - AMD SAPPHIRE RX580 in Open Core Legacy Patcher (VENTURA)

I USED to think I knew "something" about Macs until I tried to upgrade my OS High Sierra (build 17G14033) to Success' href='/2020/12/install-macos-mojave-on-supported-pc.html'>Mojave ( to go from firmware MP51.MP51.0089.B00 to 144.000.000. ALL BECAUSE it's my music workstation.

SO, after 3 days of hell, I tried to go the OpenCore LEGACY PATCHER route. I was able to install VENTURA on a wiped USB hard drive, but the for the LIFE OF ME,

I can't get it to recognize my AMD Radeon RX 580

WORKS with the Original ATI Radeon HD 5770, but not when I try to boot it with the RX 580 which is recognized NATIVE as METAL

I'm to a novice, but apparently I'm a NEW NOVICE. Can anyone help me with this issue
