    assassinXsoul got a reaction from KemalALKIN in :FIX/GUIDE: AMD Stuck At Grey/White Screen With Spinning Beachball   
    this will solve you beach ball spinning infinite grey/white screen {censored} ok i got this working the procedure is as follows on two different boards
    asus m5a97 evo r2.0

    gigabyte 990fxa-ud3

    and two different graphics cards

    gigabyte ati hd 79870 2gb

    xfx hd5770

    my processor is a amd fx 8350
    32gb ddr3 gskill ram


    i can now easily play might and magic x legacy on full graphics settings

    ok i used a certain kernel and the stock graphics drivers if you wish to change that it may or may not work

    ok procedure you now need to have kext wizard handy

    you need to head over to here for the AMD kernel


    inside that file is the kernel and the system.kext

    now you need to go over to here to grab the other two kext IOPCIFamily.kext + AppleACPIPlatform.kext for yosemite


    you will also need amd webkit patch


    now i want you to place all kext on the desktop
    if you have backed up your graphics drivers during or after the install you should be able to boot with just

    npci=0x2000 PCIRootUID=1 -v

    if not you will also need to add

    -f -x

    now once you are at your desktop you need to move the kernel over to System/Library/Kernels
    so rename your original kernel to kernel.backup1 then overwrite it with the new one

    you will then open up kext wizard and use the install pane to install

    (also if you backed up your graphics drivers nows the time to reinstall them)

    then i want you to keep kext wizard open and install the amd webkit patch after installation has finished go back to kext wizard and repair permissions (click both boxes on the bottom half)

    then reboot some of you still may have to use -v and -f

    i have mine booting with full acceleration
    without -f -v
