AMD Radeon 7770 bug graphics

Hello all, 

Hope you are well !



I have install Sierra on my AMD computer. My config : 


Mother Board ; M5A78L-M/USB3

Processor :  AMD FX(tm)-4170 Quad-Core Processor

Graphics Card : AMD Radeon HD 7700 Series  -   AMD Radeon Graphics Processor (0x683D)

RAM : 10 GB



The install was successful and I boot on Mac with the bootloader Enoch R2848 and boot flag:

-v npci=0x2000 

Sound, internet work great but the graphics don't work well, I have no acceleration graphics and bug (see capture):


Can you please help me to add kexts or other?

Thanks a lot in advance,


Have a nice day,

I may have found a possible solution to your problem Léonardhttp://www.macbreaker.com/2013/03/radeon-7000-hackintosh.html

Essentially this will be the process for your machine:

  1. Set your BIOS to default to your integrated graphics (IGPU)
  2. Plug your monitor into the Radeon HD 7770
  3. Use the following bootflags: 
-v GraphicsEnabler=No npci=0x2000


Then you might have functioning QE/CI, otherwise you'll either want to pick up a known functioning Nvidia GPU for OS X Sierra or resort to downgrading the version of OS X to a known functioning version. (I think 10.8.3 is the minimum supported version for the HD 7770 (Mountain Lion) see this post for specific variants of the Radeon HD 7000 series cards that are known to work: https://www.tonymacx86.com/threads/list-of-confirmed-radeon-hd-7xxx-series-10-8-3.92952/ )

ok I have been struggling with this for the past 2 weeks. I have installed and uninstalled Sierra more times than I can count and its been driving me potty .... have only cracked it today.  what you need to do is download create a vanilla usb stick with Sierra.  in order to do this I downloaded Yosemite.zone from the distroes  and created a usb stick.  the installed Yosemite once I was in Yosemite  ( the gfx work in this disto) I downloaded a copy of Sierra from the store..  you will have to search the net for the direct link.. I then created a bootable Sierra usb stick using unit beast, I selected legacy boot loader with no gfx injected. I then installed Sierra from this. once Sierra is installed boot from the usb and select your installed Sierra. iff all goes well you should have a working Sierra install with the gfx acceleration working.  I think the problem is with the type of Mac that Sierra thinks it is with everything working my system info is showing a iMac 27" 14.2 .  I have tried installing a boot loader on the main drive with no success so as a workaround you will have to use your usb stick.

pics below of my system info 

I hope this helped. 


I also just noticed whilst I was trying to get thing working I copied a modified andradeonx4000.kext into the root drive of the Sierra stick. I don't know if this has had any effect on the install might be worth doing the same thing

Hi have been looking into this a bit more,  it turns out it is the boot loader that is at fault.  what you need to do is copy verde.kext to your clover efi partition Clover/Kexts/10.12 then copy EMUVariableUefi-64.efi to drivers64UEFI Folder in the Clover refi partition then copy Lilu.kext and WhateverGreen.kext to Clover Kexts Other then reboot.  Have produced a how to here  With the Kexts Here https://1drv.ms/f/s!AsV7QRaRFGYgiJM_PMa-vhuv9vJ7_Q


Hope this helps.  if anyone who knows /Hackintoshing in more depth could streamline this as I don't think all the kexts are needed but by doing the above got me into a working Sierra install 

Hope this helps
