New to here, looking for kind advice to help newbie in patience.

Hi, people. I hope you're having a good day.

So, I just installed macOS Ventura to my laptop. I followed Dortania's OpenCore Install Guide and successfully made an EFI files and installed macOS Ventura. Anything except GPU and Audio, everything just works fine.

As I search to fix GPU, I found out that my current GPU status is "It shows on 'About My Mac' told as 'Intel HD Graphics 5500 7MB' but 7MB? No GPU Acceleration?" I think. I tried to use OpenCore Legacy Patcher to fix it, Root-Patching on Post-Install Menu. I also did Root-Patching, but after the patch it just doesn't boot up. Until the apple logo pops up, It seems it works fine. But at the exact moment the apple logo pops up, It changes to some kind of texts and starts to repeat writing down texts and clearing it. It was to fast to check, so let me tell some of them.

Setting BTCoex Profile: band:2

kIOFBNotifyDisplayModeWillChange notification received on Fb 2 at time 123456

Some of texts like this constantly pop up and cleared to black screen.

And for the audio, It is not detected at all. My research about it tells me that use tools like Hackintool and check the audio codec, change the layout-id till audio works. I used the tool named AIDA64 extreme to check my audio device and it was 'CX 20753/4' and given layout-id was '3, 14, 15, 21'. I've tried all of those layout-id, but it didn't work.

I'll write down the spec of my laptop below.

CPU : Intel i7-5500 U (Broadwell)

GPU : Intel HD Graphics 5500

Laptop Model : 15ZD950-GX70K (LG Gram)

Audio : Conexant Audio CX 20753/4

I think other specs would be meaningless to tell, so I'll just left those as blank space.

I'm waiting for you advice IN DESPERATE! You can give me any other specs or symptoms question anytime. PLZ HELP ME!
