Fixing 4MB VRAM Graphics Acceleration Issue on Intel HD 4000

How to Fix Missing VRAM / Graphics Acceleration on Intel HD 4000

If your macOS Hackintosh displays "Intel HD Graphics 4000 4MB" (or no VRAM amount at all) under 'About This Mac', it means graphics acceleration is disabled because the framebuffer properties are not correctly configured in OpenCore.

Step-by-Step Fixes

1. Inject Framebuffer properties: Open your config.plist using a plist editor. Navigate to DeviceProperties -> Add -> PciRoot(0x0)/Pci(0x2,0x0).
2. Add Device ID and AAPL,ig-platform-id: You must inject the correct platform layout. For mobile Intel HD 4000 (Laptops), add the following keys:
   - AAPL,ig-platform-id (Data): 03006601 (or 04006601)
   - device-id (Data): 66010000
3. Enable WhateverGreen: Ensure you have the latest WhateverGreen.kext and Lilu.kext placed in your EFI/OC/Kexts folder and enabled in your configuration. These kexts automatically apply graphics patches.
4. Check BIOS Settings: Ensure your integrated graphics DVMT Pre-Allocated memory is set to 64MB (or higher) in your motherboard's BIOS settings. A lower setting will prevent the macOS graphics drivers from loading.
