What Guidance I use:

• I follow some guidance from dortania and some guide from Rehabman to patch DSDT.

• DSDT Patch Guide : https://www.tonymacx86.com/threads/guide-patching-laptop-dsdt-ssdts.152573/

• Dortania : https://dortania.github.io/OpenCore-Install-Guide/

The part i got issue:

• The progress to make the HDMI working is quite comlicated, need to try one by one the Bus Id and the Index to get it working. I follow the guidance here : https://dortania.github.io/OpenCore-Post-Install/gpu-patching/intel-patching/busid.html
