@CaseySJ, I have 2 problems,
- I can't get the working 11.6 config on 0.7.2 I have to work when updating to 0.7.4...
- And I can't get catalina to work with 19,1!!!
I have managed to make a bootable usb of 11.6 and used your Z490 Vision D Openwireless hackindrom config but with opencore 0.7.2 and got it to boot and install. It will not boot if I attempt to update to your v0.7.4 config. It starts the bootloader and immediatly crashes, reboots and goes to recovery mode.
I wanted to stick with 10.15.7 but I cannot get the machine to boot 10.15.7 using any of the configs and 19,1.
Even if I removed all drives and use a freshly formatted ssd and the catalina installer. It starts the bootloader and immediatly crashes, reboots and goes to recovery mode.
I have gotten the usb installer with catalina to boot and install with 20,2 but I think I'm experiencing IGPU problems as firefox won't launch. vlc won't play anything, some pages refused to load in safari...
any ideas?
