What I've ended up doing on OpenCore, is making sure the DSDT I'm running on, is fully renamed.

Then, I put SATA and IGPU in a Kaby and  SATA, IGPU, and HDEF in a Coffee, in as a patch, but I set it to rename just the table SSDT's.

Rename only seems to work on generated tables in OC.

This seems to be the best I can make these two machines run on OpenCore, but they're running spot on!

I know the OC manual states against renames but I didn't put OSX on a Pee Cee to run windoze myself :guitar

Hi Maldon, 

I am trying to replace Clover with Opencore, I have used your Clover EFI and Dsdt , it has been working perfect. But when I try to boot with the Opencore Efi , it stops at "AppleIntelLpssI2CController::_serviceMatchingTimeSubr: fTimerServiceMatching timed out," and  It flashes waiting for Root Device  then scrambled screen. 

 

I didn't change anything from your EFI folder and was using Opencore as legacy. My Laptop supports UEFI but somehow Mac won't boot on UEFI with my battery in. Same case for clover and Opencore.

Actually I had some issues

1. Clover takes long time to boot, around 1min or so, and tried to clean it up to make to faster but anything I remove, breaks it so tried oc.

2. My laptop microphone doesnt have proper gain, like I can only hear tapping on the microphone, nothing else. I tried to use some guides to patch it platform.xml files but failed. 
like this one-

3. And I always wanted to use Uefi but didn’t know untill trying to work with opencore that its Mac, not the bootloader thats the issue.
