[HELP] Intel UHD 630 iGPU only showing 4 MB VRAM (i3-10105, H410M S2 V3)

[Arbitrary0984]

Hi everyone,

I’m trying to get macOS running on my build but I’m stuck with an iGPU issue. macOS only detects my Intel UHD Graphics 630 with 4 MB VRAM (no hardware acceleration). Animations are very laggy and graphics are jittery.

My specs:

• CPU: Intel i3-10105 (Comet Lake, 4C/8T)

• Motherboard: Gigabyte H410M S2 V3

• iGPU: Intel UHD 630 (no dGPU)

• SMBIOS: iMac20,1

• Bootloader: OpenCore (latest release)

What I’ve done so far:

• Added Lilu.kext and WhateverGreen.kext (latest versions).

• Tried injecting ig-platform-id values  in config.plist.

• BIOS settings: DVMT Pre-Allocated 128M, IGFX as Initial Display Output (Not able to found this setting), Above 4G Decoding enabled.

• SMBIOS set to iMac20,1.

But no matter what I try, macOS still shows Intel UHD 630 with only 4 MB VRAM.
Below i Have provide my config.plist file And also add my efi .

Try with NVRam Reset.config.plist

Remove the -igfxvesa command.

The motherboard chipset may be H510.

Thanks for the earlier suggestions 🙏

I tried the recommended changes:

• Added device-id → 9B3E0000 under PciRoot(0x0)/Pci(0x2,0x0)

• Removed the -igfxvesa boot-arg

Now, instead of 4 MB VRAM, macOS attempts to load the iGPU driver but I’m getting a black screen right after boot (system seems to keep running in the background).

I’ve attached the latest boot logs for reference.

Has anyone with Comet Lake UHD 630 (i3-10105) run into this? Should I try switching the ig-platform-id from 07009B3E to 00009B3E, or remove the framebuffer-stolenmem patch?

Any guidance would be much appreciated 🙏
