Problems I faced while and after installing MacOS in Coffee Lake Desktop

It's been 5 days using MacOS as my primary operating system. sorry for grammatical errors in advance.

My PC Specs:

i5 9500 (UHD 630)
8GB RAM 2400MHz
500GB NVMe SSD and 1TB HDD

Before you read I would like to say I followed OpenCore guide as throughly as I can but I need to use third party EFI to solve my problem earlier.

Problems I faced and fixed them:

During Installation:

My EFI literally didn't boot at all so I used third party EFI with some of my modifications and it booted successfully. to access internet I used hornis.kext to usb tether from my android phone. kexts were from OpenCore guide only. It installed without any issues.

After Installation:

1 - GPU Acceleration

I added DeviceProperties and removed -igfxvesa resulted in black screen, I just fixed it by going to UEFI settings then gpu accelerations then dvdt to 64MB.

2 - Black Screen at middle of work

It annoyed me a lot and the fix was changing the AAPL,ig-platform-id from 07009B3E to 00009B3E.

3 - Apple Store login

Just fixed it through adding payment and shipping address.

4 - Audio Issues

changing the alcid=11 in boot-args fixed the issue.

After this I changed my EFI from third party EFI to OpenCore's v1.0.0 EFI with making my changes and it worked fine!
