This card should run OOB on hackintosh 10.7.x, and 10.8.x computers, however, not in my case :). If u put GraphicsEnabler=No, as somebody described in some tutorial, everything seems to work perfect, until you try to use DVD, or some software like Ableton or Resolume, or most of the games which crashes instantly. I think that the problem is in ATI d-sub connector, there are also a DVI and HDMI connectors on this card (you should use DVI connector), so probably OS X have a problem with d-sub which is not used any more on mac computers…
To fix this problem you should add this lines in your Boot.plist file (mine is located in Extra folder, called org.chameleon.Boot.plist). No extra kext file is needed to install this card.
<key>GraphicsEnabler</key> <string>Yes</string> <key>AtiConfig</key> <string>Pithecia</string> <key>AtiPorts</key> <string>3</string>
In some cases you will also need to ad this flag, test it for yourself and see if it works.
<key>Kernel Flags</key> <string>PCIRootUID=0</string>
Save it and reboot.
For 10.7.4 Lion that should be it, it fixes all problems, and everything seems to work normal now… you should be able to use 100% of your Radeon Sapphire HD6670 graphics card :).
While installing OS X 10.8.2 using UniBeast you will probably get a “white screen with a cursor” error on the installer, it is due to a bug on “ATI6000Controller.kext” drivers on the installer, you have to remove the /System/Library/Extensions/ATI6000Controller.kext from the install media and boot it ignoring caches and disabling Graphics Enabler ( -f GraphicsEnabler=No ). Remember to make a copy of “ATI6000Controller.kext” before u delete it, you’ll need it later when you will install your system.
If you used MultiBeast to install bootloader on your HDD you will need to boot with GraphicsEnabler=No option every time until you do this steps:
copy ”ATI6000Controller.kext” you removed from USB installation media into the /System/Library/Extensions/ on your HDD. Run Kext Utility to fix file permissions.
Open /Extra/org.chameleon.Boot.plist and after
add this lines:
<key>AtiConfig</key> <string>Pithecia</string> <key>AtiPorts</key> <string>3</string>
Reboot your computer and you are good to go 🙂
Updated to 10.8.3 via software update without problems.
Here is updated tutorial for Mavericks users!
