    SAPPHIRE HD 7850 2GB not working on Mavericks

    Hello, So here I am, I did a clean installation of mavericks (10.9.0), made some changes in the DSDT etc.. But now, when the boot up process seems to be completed the monitor turns off. I have the feeling that every time my graphics card is working the monitor isn't. I tried with: - PCIRootUID=0 & PCIRootUID=1 - npci=0x2000 & npci=0x3000 - "Graphics Mode"=1920x1080x32 ... Any suggestions ? DSDT.zip

    ---> Which of you is right ? PS: I changed the device ID but it still not working. I guess my system isn't up to date because the version of AMDSupport is 1.1.4 while the one required by AMD7000Controller is 1.2.0. So I'm looking for an older AMD7000Controller.

    I tried these kexts but they don't seem to work. When I try to load AMD7000Controller.kext the error message is exactly the same as it was before: Here's the output with kextutil(terminal):

    Because I want to solve this problem and I prefer Mavericks to Yosemite. Thanks for your help though.

    @artur-pt: I already boot with GraphicsEnabler=No (boot.plist) and I tried your boot flags the result still the same.
