  1. If you have an Ivy CPU with a 6-series board (rare) or a Sandy CPU with a 7-series board (not as rare), you'll probably have difficulty reaching the installer even if you provide the correct "ig-platform-id" or patch the DSDT. The graphics drivers are dependent on the driver for the Intel MEI device. Apple put the MEI driver for the 6-series boards is in the same kext as the HD3000 controller, and the MEI driver for the 7-series boards in the kext for HD4000 controller. This is why it is impossible to load the framebuffer from the HD4000 controller, using the MEI for a 7-series board, when you have a HD3000 controller on a 7-series board. Similarly, it is not possible to load the framebuffer from the HD3000 controller, using the MEI for a 6-series board, when you have a HD4000 controller on a 6-series board. You can fix the IMEI with the Clover EFI bootloader and patch the AMD Controller/Framebuffer in some cases. Assuming that you have both a HD4000 and Radeon HD controller, you might just consider disabling the discrete GPU capabilities completely. As for the Radeon HD, it is always a "shot in the dark" getting them to run properly. Even when you decode the VBIOS, and patch the right framebuffer in the AMDXXXXController, there are several different chipsets in the same series. If you get the right Intel Management Engine, the right framebuffer, and the right ASIC chipset architecture you'll have full QE. Forcing your GPU to run a different architecture, and having an incomplete EDID, will give you graphical anomalies.
