hi Middleman,

I tried to install high sierra with your EFI file, but after entering OC and choosing to install, it will reboot after seeing the Apple logo for a moment and cannot enter the installation screen. I'm using Gigabyte Z490 UD + i7-10700 + GTX960. Please tell me what edits to make in config.plist and kext under my system for a successful installation?
Hi Bajayhans,

Okay, so I've had a look at your board specs and edited the EFI file with v2.25 Opencore Configurator according to how it should be set.

These are some of the changes I've made:

- Disabled SSDT-TB3HP for Thunderbolt and the Airport kexts for the WiFi (as it has no WiFi card slot)
- Removed the Aquantia and Intel 2.5Gbe LAN device properties and other properties (for failsafe booting)
- Changed the IGPU device id to Coffee Lake spoofed to 0300923E (as you have a i7-10700)
- Added shikigva=256 for Nvidia acceleration for your GTX970

I'd also updated the OC boot files to v0.6.5. Apparently they were still on v0.6.1 (my mistake). It should work better overall now. All you have to do is add in your own serials into the Platforminfo section (where I've marked the fields that needs to be completed). You will need to generate your own serials, UUID and ROM value. ROM can be your Ethernet card's LAN address. It may be found either in your BIOS as a device or Windows device manager under the Realtek LAN.

You'll need to enable your IGPU in BIOS and set it to either Auto or enabled and connect the system via the Nvidia card. If and when it successfully boots into macOS you'll also have to add the Nvidia CUDA and Nvidia webdrivers. But overall it should work. Give it a try.

Sorry, I ran into a problem at the beginning. I checked the information and it seems that oc didn't catch "FakePCIID_Intel_HDMI_Audio.kext", but it is stored in the folder.

that boot argument has nothing to do with enabling hardware acceleration for any video cards

Actually it does. Because it comes from the Whatevergreen changelog:

Shikigva=128 has been used to drive AMD cards before and shikigva=256 is the Nvidia equivalent as far as I am aware. It has worked for me when I run my GTX 1060 on the Z490 under High Sierra.

that is different to getting hardware acceleration working :)

I tried the EFI file attached in the post and tried a few others and changing values with no success
this is what I get
ACPI Error.jpeg


double-checked the BIOS setting and everything seems fine

These are my specs:
I9-11900k
Asus Z590-A
trying to install it on a Crucial P2 250GB M.2
and use the IGPU
I just need to boot it so I can use Xcode
