Started my adventure with MP4,1, updated to 5,1 and x5680 and after few installation attempts I finally managed to install Ventura 13.2.1 using 0.61 OCLP, but whenever I try to boot with RX 580 installed the system does not boot to OS, it boots to boot recovery assistant and tells me I have to reinstall the OS, if I switch to GT120 the system boots fine but there is no acceleration, I just did a clean install with RX580 all the way through installation process and got exactly the same result, Mac won't let me boot with both GT120 and RX580 installed in the system, it hangs as soon as loading bar appears underneath apple logo... tried to prepare the installation usb on iMac 13,2 and Mac Mini 2018 no difference, what am I doing wrong? The same thing was happening with 13.1 installed, I also tried Quadro K600 GPU which gave the same result, tried with 1660 super and even got boot screen, again the system does not have acceleration but boots to OS, is there some setting in OCLP I need to select to allow it to boot with metal capable GPU?

Could this be related to KDK (whatever that is) being not available online? I noticed this earlier when OCLP asked me to install root patches for Tesla and USB 1.1 (I think it would not work for GT120 anyways) it just thrown an error that KDK was not available online... I just clicked to reinstall and got that msg Installation requires downloading important content and it cannot be downloaded at this time...

Thanks, I worked that one out, Ventura wont boot with metal and non metal gpu's installed at the same time, my problem was to do with developer settings, when I selected AMD GOP injection it worked, I got to the OS, then it was KDK, had to manually download kdk for 13.2 which allowed me to install root patches, I also did the OCLP 0.62 compile and that one actually downloads the KDK automatically... it is all working now :D well kind of, I wanted to see how Fortnite is running on MacOS but it crashes as soon as splash screen appears, this is with Vega 64... Is it actually worth keeping Vega 64 or should I just get much cheaper RX 580?

You should get the similar priced RX6600
