Well, the OS X 10.8.3 update is finally out, and the big news is the diverse new graphics support. Apple's added drivers for some AMD Radeon HD 7xxx graphics cards to OS X. There are a few tricks required for enabling these cards, so we're not recommending them officially yet.

OS X 10.8.3 devices supported:
AMD Radeon HD 7750, 7770, 7870, 7950, 7970

How to Boot using AMD Radeon HD 7xxx:
The AMD Radeon HD 7xxx must be the secondary graphics device in your system in order to boot using Chimera/Chameleon without a boot error and gibberish text. This is because of the larger video BIOS size. You can work around this by having a second AMD PCIe card in your system, or if using a motherboard with integrated graphics, set it to display first. The primary graphics device will handle the boot portion, and allow the system to boot perfectly with full graphics acceleration.

For current Gigabyte motherboards with AMI UEFI, set these two settings for dual graphics.

Init Display First: IGFX
Internal Graphics: Disabled (OS X will recognize fully)

You can use GraphicsEnabler=Yes, use default GUID partition format, and everything should work.

For Gigabyte motherboards with Award BIOS, set these two settings.

Init Display First: Onboard
Onboard VGA: Always Enable


You may have to use GraphicsEnabler=No in order to access the desktop successfully.

Please don't view this post as buying advice. AMD Radeon HD 7xxx support is experimental and may or may not ever be fully supported by the tools and operating system. If you have one of these devices, add your test results here. Have fun!

As long as it shows 7xxx it doesn't support full acceleration. DSDT injection with the sleep trick is one way, or using a hybrid EFI vBIOS with the Clover UEFI bootloader.

I've benchmarked and confirmed it's working with full acceleration. Chimera doesn't have 7xxx GraphicsEnabler code- that's why you see the "7xxx" while using GraphicsEnabler=Yes. And the fact that there are no official Macs with 7xxx means that the drivers are injecting default values.

The DVI-VGA adapter is working? I have a HD7770-DC-1GD5-V2 graphics card.

Why can I see a working mouse cursor with a white background? The SleepEnabler Trick is not working for me. :( I have a HD 7770 graphics card on the AsRock Fatal1ty Z77 Professional Mainboard but would be really happy if someone have a SleepEnabler.kext for my Mainboard or a working method without the SleepEnabler.kext. I have to add that I had deleted the kext for my internal Graphics, because otherwhise i got a KP

Edit:
These are the fixes for my problem:
-latest Chameleon Bootloader

Felix, did you try using Clover UEFI?

No I use the newest Chameleon, but what does Clover UEFI do instead of Chameleon or Chimera?

"You can work around this by having a second AMD PCIe card in your system, or if using a motherboard with integrated graphics, set it to display first."

does this mean the monitor must be plugged into the onboard GPU in order to work? Basically I have a Gigabyte UP5-TH with a 3770k/HD4000 IGPU, and an XFX 7950 in the PCI-E slot. I have triple monitors plugged into the 7950. I don't want any monitors plugged into the onboard, do I have to do that in order to make this guide work? Can't test right now as I'm in class.

Thanks for any replies!

No, although I used 2 monitors, using this method you can boot "blind" into the os using just one monitor. When things come up, you should have full access to the AMD card.

Is there any solution for my problem out yet without using Clover?

Thanks for every solution or reply :)
