Black Screen with MacPro 6,1 or iMac 15 or iMac 17 System Definition

Z97 and 15,1 but I'm using the integrated HD4600 and having this issue from the main post. Main post is only for add-on GPUs. What about HD4600? Any recommendations? Thanks.

Enable Inject Intel and use the ig-platform-id 0x0D220003.

You can just use Clover Configurator. Set the Boot Display property to the correct port number on your GPU.

Looks like you are using port 3. Search your ioreg for AppleDisplay and you will see it.
