Article: AMD Radeon HD 7xxx Graphics Support in OS X 10.8.3
There is no hard support, just not ready yet, be lucky that we have ways to inject...
Where is the problem? A little white screen bug if not using UEFI? Not a big deal till there are other ways...
Prosaca, Thank you for your response and advice.
Since I really believed that "updating for OSX 10.8.3" means that I can start(enjoy) the fully use of HD7970 power on my Hacintosh, it was sad for me that my GTX480 graphic board ( just mounting the cooller part of Intel RTS2011LC ) can not activate on the 1st PCIex16 slot ( of Sabertooth X58). It can be run on PCIex4 slot so that my powerful HD7970 board is not activate on the 2nd PCIex16 slot.
After seeing following words from Tonymacx86, I decided to buy the HD6870 board as the special price and replaced for old graphic board (GTX480).
"You can work around this by having a second AMD PCIe card in your system,.."
This afternoon, I did the fully enabling the power of HD7970 in displayport as below.
a. Remove the GTX480 board and several parts of RTS2011LC from my Hacintosh ( that is run in the HAF XB Lan Box) - PICex4 slot.
b. Install HD6870 board into the 1st slot of PCIex16. Then, run OSX 10.8.3 under the booting of UniBeast 1.7 (boot option as GraphicsEnabler=No ).
c. After the completion of OSX 10.8.3 boot, I run Multibeast 5.2.1 for putting the bootoption GraphicsEnabler=No into my Hacintosh system image.
d. Checking out that my Hacintosh can be booting and run Firefox on 10.8.3 on HD6870.
e. Then Activating my HD7970 board by connecting 2x PCIe 8pin power plug. Re_boot with Unibeast 1.7.
f. Checking out both AMD grahic board ( DVI connection from HD6870 and Displayport connection to HD7970)
g. Enjoy the great power of HD7970 ( which cane be provide us 2Tflops and more ).
Thanks Hacintosh greek for providing the advice and energy to make the change.
