I've got a Mac Pro 5,1 running 144.0.7.3.1 bootrom and Mojave. I'm trying to run open core legacy patcher 2.4.1 to install a newer non supported Mac OS. I also have a RX560 (Mac flashed & metal supported) videocard installed.
I am not sure why I am having this problem and have tried everything I can. I've installed OCLP to a freshly formatted SATA HDD then I rebooted the system to boot off this HDD. The Apple boot picker appears as my post picture. I then select the OCLP EFI option, the screen goes blank for 2 seconds (no text appears at all even though I've ticked the Verbose option in OCLP settings). Then after 2 seconds, the Apple boot picker reappears. For some reason the OCLP patching is not running. I am pulling my hair out with this issue.
🙏 Brain trust please help
