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 Code (Text): [COLOR=#000000]7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d00690064000000080000000b006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31[/COLOR] 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.
