Success - AMD Radeon HD7XXX support

[knightjp]

It took a bit of searching, but I finally got my Radeon card to work with Mac OS Sierra. After the initial installation, and the computer restarting, it just comes to a black screen. Nothing else is there and I cannot complete the installation. I managed to do so while booting into safe mode. You do this by putting the "-x" boot flag on Clover.
But you cannot install MultiBeast when you boot into safe mode.
After completing the install, I came cross a russian site talking about the HD7770 card I have. It said that once you copy "Verde.kext" file into the Kext folder of Clover (EFI/Clover/Kexts/Other/) you will be able to boot up without any flags needed.

So the next step for me was to use UniBeast again, re-download Sierra and make a another bootable USB. After Unibeast is done, copy the attached kext to the EFI/Clover/Kexts/Other folder of the USB. The installation went through without any issue. After installing the MultiBeast, I copy the kexts over from the USB to the EFI partition of the HardDrive and we're done.

I'm just passing on the information for those struggling with the support for the same card. The kext works for El-Capitan and Sierra (tested)

I believe all that kext does is allow multiple IOPCIMatches for the Cape Verde (77XX) series, altering the AMDRadeonX4000 kext. Some of the cards aren't supported tho I remember reading this in a Radeon thread posting.

Thanks for sharing, I have a 77XX card on my Desktop in which I will be installing Sierra on very soon. This may come in handy if I can't boot without the screen being black.
