Modified 128mb aptio file with 0x3 does not work on an ASROCK Z68, however 0x67 with the old aptio works fine, although it'd be great if I can switch back to 0x3 as it was prior to 10.11.4 Using OsxAptioFixDrv2-64 gets me small and random Intel HD3000 graphic glitches/artifacts.

Well, the whole point for that modified 128mb Osaptiofixdrv-64 was so that you could use it with a csr of 0x3 because you could already use 0x67 with the non-modified aptio version.

Hi toleda, I tried both ways, with a vanilla AGPM.kext. I first enabled HD3K on the bios, edited my DSDT renaming GFX0 to IGPU, PEGP to GFX0, added the DSM methods under IGPU and HDEF address, so on and so on... HD3k worked wonderfully with a vanilla AGPM and GE=No, unfortunately i got no use...

Hi Toleda, I'm having a problem with my EVGA GTX 570 HD card (Vendor10de 1086). I did exactly as directed on post #1 with the AGPM edits, however i can't get the system to boot on Mavericks (have not tried ML/Lion), this is how the screen looks before it goes black -> blue -> monitor turns off...

Sure, i've attached it. works only on 10.7.2, when 10.7.3 comes out a new patch would be needed. Also, make sure you dont have NullCPUPowerManagement.kext in either /Extra/Extensions or /System/Library/Extensions directories, if you have it installed (multibeast usually installs it) then you...

Can you copy-paste the last lines you get in the console.app when it happens?

It has to be done through terminal like explained on the speedstepper thread: sudo bash; ./speedstepper /System/Library/Extensions/AppleIntelCPUPowerManagement.kext/Contents/MacOS/AppleIntelCPUPowerManagement

Can you boot with the -v flag and take a picture with your cellphone camera or any other camera you got and post it back so i can look into it? thanks.

Sure, there you go, make sure you update your bios version to 1.30 through InstantFlash and then place the DSDT.aml in your Extra Folder and you should be all set.

Hi Toleda, I'm getting this error spamming my console with the latest ALC892 AppleHDA.kext as reported on here. PM kernel: Sound assertion "kTypePinComplex != fType" failed in "/SourceCache/AppleHDA/AppleHDA-179.1.4/AppleHDA/AppleHDAWidget.cpp" at line 1901 goto Exit Maybe an specific...

Glad you got sleep/wake working on the Extreme4, can you attach the original DSDT and the patched one? i do have a few other DSDT modifications i ported from another asrock z68 dsdt mald0n patched a while ago, though i'm not sure if they would help with the geekbench score but it doesn't hurt to...

Impressive! Onboard ALC892 + GTX570 HDMI binpath working on this flawlessly, i can switch between internal speakers and HDMI audio with no problems! Thanks so much for your time, much appreciated :thumbup:

Sure, will try out and post back, thanks :thumbup:

Just tried it and no luck unfortunately. Tried doing a few cold boots and unplugging the power cord but nothing, only HDMI audio worked well, tried internal speaker and any other output line but nothing on this board.

For what specs is this? alc 8xx? nvidia hdmi? or hd3000?

Thanks toleda! Will try out that and report back

Same process for the GTX570, edit Info.plist on that kext and full res on next reboot.

Haven't tried on SL, i installed Lion from the get go without having an SL install, i made my lion usb installer using a second mac.

Unibest and lion retail downloaded from app store is all you need
