10.8.3: AMD Radeon HD 7xxx Graphics Testing Thread

[neuroman]

You don't need a modified kext.
I personally use the Asus 7870, I don't need any boot flags to get the card working.
But, your problem is, that you need to boot with your igfx as first or install the boot loader to the efi partition of your drive, or you should try clover.
With Chameleon or Chimera it is the problem, that hd7xxx cards are not correctly recognized.
clover has no problem with those cards.

That is not entirely true. The problem with Chameleon or Chimera is that the cards vbios memory causes problems and therefore needs to be secondary to avoid the corruption. The way around it is to move the bootloader to the EFI partition as discussed previously on this thread. You can also boot using another medium , most commonly USB. Finally, another way to avoid the corruption is to use clover.

Thank you for your answer.I change my mind and I use a MSI GTX 580 TWIN.I do not like AMD Cards,don't work fine on Hackintosh.

Hi Wundorn. Below unfortunately does not work. I guess fp-rotate does require user login. Thanks anyway.

OK, how about this? I want a certain network volume mounted as soon as I boot, and there's no reason you can't use the same technique to do this screen-rotation trick. First create the file /Library/LaunchDaemons/localboot.plist, and put this in:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC -//Apple Computer//DTD PLIST 1.0//EN http://www.apple.com/DTDs/PropertyList-1.0.dtd >
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>localboot</string>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/local/bin/boot.sh</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>LaunchOnlyOnce</key>
    <true/>
</dict>
</plist>

That tells your Mac that when it boots, it should run the shell script "/usr/local/bin/boot.sh". Once that's done, create /usr/local/bin if it doesn't exist, and make the shell script containing your fb-rotate command. Note that this script will execute as root, not as any user, so you probably want fb-rotate to go in /usr/local/bin as well, and you should invoke it using a complete path. So, you'd make it look like this:

#!/bin/sh
# rotate screen twice to overcome white screen startup bug.

# If things aren't working out, you'll need to redirect output to someplace you can
# actually see it, by uncommenting the next line
# exec 2>&1 >/tmp/boot.sh.output.txt

/usr/local/bin/fb-rotate -d 0 -r 90
/usr/local/bin/fb-rotate -d 0 -r 0
# Any other startup code can be placed here

Lastly, do "chmod 700 /usr/local/bin/boot.sh" and "chown root:wheel /usr/local/bin/boot.sh" in case you ever decide to put anything there that you don't want prying eyes to see (like low-security passwords). If you created /usr/local/bin, make sure local and bin are owned by root and mode 755.

Let me know how this goes. I can imagine a slight possibility of this not working: fb-rotate might want to execute in a user session. But as long as it works OK when nobody is logged in on the GUI, it should work fine this way. (You can test before doing all this stuff by logging out all users, and then sshing in from somewhere else.)

is there anyway to use R7 260X (7790) on mavericks?
or is there any hope for support in Yosemite !!!!??

I have installed Sapphire 7950 successfully on 10.8.5 with Clover. It turns out that Clover seems to be a really good solution which leverages UEFI

For a couple of versions of Mavericks I had to edit the plist for the display driver to substitute my cards vendor and device id's. Since the latest version of Mavericks though, it's simply worked with no mods.

I don't know where versions you have tried, but if it doesn't work with the latest version of Mavericks, you should be able to edit the files manually. There are instructions on this website for do so, you should be able to use the ones for the 7850, same driver files.

Hello everyone. I have a problem that does not allow me to recognize my Radeon hd 7990. I would be fine that was recognized even one video card but at the moment the only video card that is recognized is the Intel HD 3000. I have seen the procedure described here that allows you to enable the dedicated video card, the problem is that when I select the bios IGFX and I disable the integrated card, then save, when the pc restarts and return to the BIOS I again set Auto in "Init Display First" while the integrated card remains disabled. If I try to start Mavericks in this way, the resolution is very low and the specification of the system I have 3 mb of video memory with no other information.
If, however, imposed under the voice "Init Dispaly First" IGFX and I enable onboard video, Mavericks starts in Full Hd recognizing the Intel HD 3000. I'm going crazy because everything else works perfectly and I would not be forced to change the video card that at the moment is liquid cooled.
I kindly ask for help.

Thank you in advance.

Hello! Did you managed to run successfully a HD7990 on your build? If you did, even as a single 7970, please post your solution. I have one of those and no plans to change it. Have been trying to do it but with no success.
Thank you.
