10.6.8 Released

Just use old update guide

  • fermi users – reinstall geforce/nvda kexts from 10.6.7 imac2011 update after installing 10.6.8.
  • Got panic from appleintelcpupm kext durring installing (have speedstep activated via dsdt), it could be best to use nullcpupm durring installation.
  • New applehda was changed too much, easier to use 10.6.7’s one.
  • New IOPCIFamily is same as Lion’s, looking forware to 10.6.8 source release if have problems use old iopcifamily and appleacpiplatform kexts.
  • fixed atheros wifi with installing this form 10.6.7 update – /System/Library/SystemConfiguration/Apple80211Monitor.bundle

    QE_CI_Exotic_patch doesn’t include

    Chipset Model: ATI Radeon 4890 Series
    Type: GPU
    Bus: PCIe
    Slot: Slot-1
    PCIe Lane Width: x16
    VRAM (Total): 5 MB
    Vendor: ATI (0x1002)
    Device ID: 0x9460
    Revision ID: 0x0000
    ROM Revision: 113-B7710C-176
    EFI Driver Version: 01.00.318

    Adding it myself seems to lead to no luck either

    Oh… never mind, it does, I was looking at the revision ID not the vender ID…

    DAMN… then I have no idea why this is not working for me, if I use the package all I get is a gray screen with little black pixels all over the place. If I try just adding the info.plist to the default mac 4800.kext and using your x200.kext I just can’t get QE or CI to work

    On a MacPro 2,1 after upgrading to 10.6.8 and the new exotic patch, Flash does not work in Safari or Chrome but does in Firefox. (I get a sort of transparent window in Safari and Chrome.) In addition. Grab does not work. I had no problem with 10.6.3 and the exotic patch and wonder if something went wrong in the upgrade process.
    Anyone else seen these problems. The card is a Cindori rom flashed 4890 that has been perfect until now.

    MacPro 3.1 with saphire 4890 working on one monitor.
    When the other monitor is plugged in, the system blinks once in a while. It’s like trying to detect the monitors.

    Any one experience this too? If any solution?

    update to 10.6.8, then install 10.6.8 qe_ce_exotic on Saphire 4890 HD and works perfect for me. Thanks Netkas !

    That’s what I did first time but no QE/CI.
    However, running Zeus 2.5 from Cindori found that no QE/CI drivers were installed so I did it over using Zeus and that fixed the problem except that AE would no longer allow me to access openGL. That was fixed by deleting the AE plist and all fine now.
    Thanks netkas and Cindori.

    Corrupt video on the 4890 with this patch (removing the X2000 kext allows me to boot, but locks me at 1024×768). The video card is recognized in the System Profiler, but I can’t set resolution any higher.

    When I install the QE/CI patch here (the X2000 kext) the system boots, but the image is corrupt (3×3 grid of duplicated images, with noise/lines/random color). You can tell it has booted properly, because when I throw my mouse to one of the hot corners, the colors change to be predominantly the color they would normally change to be.

    Any ideas?

    ^ XFX HD 4890 if it matters. Was previously using 10.6.5 with no problems.

    @ Ronni,

    Yes, I also have this problem. 1 monitor, either port is fine. 2 monitors – constant flickering. Mac Pro 1.1, Sapphire 4890

    Thanks netkas, for some odd reason my MSI 4850 needs this. (and I have tried both Legacy4800 and modding ATI4800 kext). Scrambled screen otherwise.

    I fixed my ethernet after a failed attempt at using the Apple80211Monitor.bundle.

    I ended up adding the SMboardproduct key to my smbios.plist with a value of Mac-F4208CC8. (SMproductname is MacPro3,1)

    I opened the new 10.6.8 IO80211Family.kext and noticed in Plugins there is a new kext named AirPortAtheros.kext with the device ID already there! so I removed my E/E IO80211Family.kext completely. I also had to remove the Apple80211Monitor.bundle I added in my initial attempts to fix this issue.

    So conclusion: running new 10.6.8 kext! and only had to add the SMboardproduct value to the smbios.plist…

    BTW my airport wannabee card is a Dlink DWA-542 version A2

    update to last post – looks like when booting in verbose mode an error occurs “…link down (unspecified)”

    Not a big deal but the wifi needs to be turned off then back on each boot.

    Anyone know why?

    Just upgraded to 10.6.8 and noticed immediately that wifi was broken. Reverting the atheros bundle to 10.6.7 fixed it. Netkas is god.

    Hello netkas,

    On 10.6.7 I got around 60fps on MineCraft using my sapphire HD 4890,
    But After updating to 10.6.8 I only get around 30fps…

    Can you help me?
