IORegistryClone VS OpenCore-Install-Guide

First of all make sure you have a backup of your current EFI then try some patching. Then grab a copy of IOReg and open it. Search for iGPU entry and locate entry (eg. AppleIntelFramebuffer@0 in my case) with a child “display0” it controls the physical display. Select that entry (eg. AppleIntelFramebuffer@0) and on the right panel locate connector type. Then check if it’s set to “00 08 00 00” or not. (This is the connector type for HDMI). If not then. Leave it as it is (in case of laptops it is mostly 02000000). Then open your config.plist in propertree and head to DeviceProperties -> Add -> PciRoot(0x0)/Pci(0x2,0x0). Then add these entries here (Don’t touch anything already present there just add these) “framebuffer-patch-enable = 01000000”, “framebuffer-conX-enable = 01000000” and “framebuffer-conX-type = 00080000” [IMPORTANT: make sure X in conX is the number you’ll find in the ending of AppleIntelFramebuffer@ which you located previously and make sure it has a child “display0” this is important (in my case=0)] and save the config.plist and reboot. Your HDMI port should be working now. Not 100% sure about it but it works most of the time.

Check dortania’s open core guide

To keep costs down, Keep an eye on local market place and classified sites for a cheapish gaming PC with an AMD card in it (RX’s 5700 / 5700xt / 5600xt / 6600xt / 6600). Look up the parts here on Reddit and https://dortania.github.io/OpenCore-Install-Guide/ to see if people have problems or methods needed to make them work.

Idk much about amd gpu support but u can check it on Dortania’s open core guide which I highly recommend you to follow

Btw u can follow this https://dortania.github.io/OpenCore-Install-Guide/

I have similar setup (i7 8700K, 5700XT, Asus Prime Z370-a), everything works, no issues (wifi with OCLP patches). All you need is here: https://dortania.github.io/OpenCore-Install-Guide/

Go through the Dortania Guide.

I exclusively used OpenCore Dortanias Guide. I also useed OC 0.9.5
