Force-enabling graphics with a fake Platform-ID

⚠️ This is for users who don't have graphics output at all. It's only a temporary solution to force-enable software rendering of graphics in macOS, so you can at least follow the instructions on-screen to generate a proper framebuffer patch. If your display is working already, skip this step!

First try adding -igfxvesa boot-arg to the config.plist and reboot. This will enable VESA mode for graphics which bypasses any GPU and uses software rendering instead.

If this doesn't work, we can inject a non-existing AAPL,ig-platform-id via DeviceProperties into macOS, which in return will fall back to using the software renderer for displaying graphics since it can't find the Platform-ID.

Booting with this hack will take much longer (up to 2 minutes), only about 5 MB of VRAM will be available and everything will be running slow and sluggish – but at least you have a video signal.

Enabling a fake Platform-ID in OpenCore

  • Open your config.plist

  • Under DeviceProperties/Add, create the Dictionary PciRoot(0x0)/Pci(0x2,0x0)

  • Add the following Keys as children:

    Key Name Value Type
    AAPL,ig-platform-id 78563412 Data
    framebuffer-patch-enable 01000000 Data

    The entry should look like this:
    OC_fakeid

Enabling fake Platform-ID in Clover

  • Open your config.plist in Clover Configurator

  • Click on "Graphics"

  • Enable Inject Intel

  • In ig-platforrm-id, enter 0x12345678 (you can omit the 0x)

    This is how it should look in Clover Configurator:
    FakeID

NOTE: Make sure to delete/disable the fake Platform-ID once you have generated your Framebuffer patch!
