  1. Yes, it seems others on this board have had to go to iMacPro1,1 SMBIOS and disable integrated graphics in order to get away from AptioFix2Drv-free2000.
  2. Thanks for sending that over! I cleared NVRAM with f11, but I didn't get very far with with that EFI. Right after booting, it gave me a "Couldn't allocate runtime area".
  3. Stopped working for me with the update, I had to fallback to editing the DevicePolicy plist again.
  4. Thanks, this finally fixed the nvidia black screen issue without having to modify the Info.plist directly. I'm running with SIP enabled again

    10.6.8 officially released

    Just rolled back to the ATI kexts from 10.6.7 and XFX 5770 works fine again.

    Yes same thing for me, it gets to the end of boot in verbose then just sits there. I can ssh into the machine so it is up and running, just no graphics.

    Looks like the problem is specific to the XFX 5770 card. I have the same one and can't get into desktop anymore either. I've seen reports of others with that card having the same problem. Looking forward to a solution if anyone comes across one!

    ATI HD 5770

    To answer my own question, you do not need to reinstall. Just drop in the required changes and you should be good to go from your existing install. However, I did run into some random screen freezes (mainly to white) which seems to have been fixed by reinstalling the Snow Leopard Graphics Update and/or extracting my own XFX rom with GPUz in windows. I'm attaching my extracted ROM from XFX 5770 if anyone needs it. 1002_68b8.rom.zip

    ATI HD 5770

    I've currently got an nvidia card running on 10.6.4 with the graphics update. Can I just swap in the 5770 with the required changes (boot file, rom, etc) and expect it to work? Or does this involve a reinstall of the entire OS? Thanks!
  10. Excellent work Tony! Now let's hope 10.6.3 (which sounds like it is getting closer) doesn't bring any HDA suprises.
  11. My UUID has remained stable ever since I switched to RC4 and removed platformUUID kext. I'm not using Rekursor's patched version and I have no entry in com.boot.plist.
  12. Ok, another brief update on the static/electronic noise issue. The noise does appear to be coming from the power supply when power management features are enabled. I did some more searching and came across this thread: http://forum.corsair.com/forums/showthread.php?t=75330 It seems there are a lot of people that have similar problems with corsair power supplies. One suggestion is to disable EIST and C1E settings in bios, but that did not work for me. I remember someone said that people with Seasonic PSUs were also having this problem. Turns out that some Corsair PSUs are OEM Seasonics.
  13. Thanks Tony, but I think I've got myself into a catch-22 here. Using that DSDT, I'm not able to boot without NullCpuPowerMgmt (kernel panic). And the noise only happens without that kext, so I think I may be at a dead end with this idea.
  14. Hmm, I have a Corsair PSU and an x25 as well. Is there a straightforward way to remove the sleep patch from the DSDT? I would like to validate that the problem is with that code. I may have to pay a visit to TonyMacs blog and do some research on DSDT editing finally (I was hoping I was never going to have to learn this DSDT stuff hehe).
