EDIT: UPDATED AS OF 22-APRIL-2013
AS of 10.8.3, the stock Apple kexts include the dev-id of the Ivy Bridge HD2500 IGPU.
Know issue:
- Works only with DVI/HDMI. No analog VGA.
Prerequisites:
- Connect your display to your motherboard's DVI or HDMI port.
- Enable the integrated GPU in your BIOS/UEFI
- Set the vram in your computer's BIOS/UEFI to 32MB.
- Mac OS X 10.8.3+ with untouched kexts.
Instructions: (Tip: Use the chameleon wizard app)
1- Enable Chameleon's Graphics Enabler.
2- Set smbios to Macmini6,2
3- Inject the following EFI device properties
ig-platform-id: 0166000B, Shared RAM for FB: 32MB, Pipes: 2, Ports: 3, FBMem: 2
On reboot, the card will be detected as Intel HD4000, and you'll have full resolution and QE/CI
Troubleshooting:
If it doesn't work, you might need to inject the platform-id using DSDT.
Remove the string and disable the Chameleon's graphics enabler.
Find the device with address Name (_ADR, 0x00020000) and rename it IGPU and add this method right below the line. You may need to renames all references to this device in the DSDT to avoid compile errors.
