Yes, that's what I linked in the post above.

See here for fix For audio, did you copy the kexts from kext/other/LE to /Library/Entensions and run the permission fix? Make sure no error after the fix, otherwise run the last 2 commands again until successful

see ypdeveloper's post here . You need to set Legacy rom in BIOS to fix the glitch issue. Install Clover to the HDD as you did with the USB and copy the EFI folder of the USB to the hidden partition EFI of the HDD

Download this, place it in the root of you USB installer. Boot to the installer and copy it to /System/Library/Extensions sudo cp -R /Volumes/USB/AppleIntelBDWGraphicsFramebuffer.kext /Volumes/jojo/System/Library/Extensions/ For 10.11.3. The one by ypdeveloper is 10.11.0 I think. AppleIntelBDWGraphicsFramebuffer.kext.zip

You can either use the DSDT plus E6420 bootpack here which includes the patched version of AppleHDA or you can modify the info.plist of VoodooHDA. Look for these under IOKitPersonalities and change it to true VoodooHDAEnableHalfMicVolumeFix VoodooHDAEnableHalfVolumeFix VoodooHDAEnableVolumeChangeFix VoodooHDAEnableMuteFix

See this guide. Use the E6430 or E6230 bootpack depending on the display resolution. Leave out the DSDT/SSDT. Boot to Clover GUI, hit F4 and then boot to the Installer to continue the build. Compress /EFI/Clover/ACPI/Origin and upload it here and I'm try to patch it for you.

Did you run through the EDP install? The chart shows that HDMI Audio is supported. To patch the kext, you'll need to get the codec_dump from linux.

Was the FB kext in your USB patched? or vanilla? If the patched kext is elsewhere, copy it from that location.

Assuming you have the patched FB in your USB installer, that's why you're able to boot and install OSX Boot to the USB installer, click on Options -> open Terminal, and enter the following: diskutil list sudo cp -R /Volumes/<name of your USB installer>/System/Library/Extensions/AppleIntelBDWGraphicsFramebuffer.kext /Volumes/<Your OS HDD>/System/Library/Extensions/ Close terminal and reboot to your HDD

@sebus Try this bootpack, works on my 9020 with Yosemite. Replace your EFI with this ( rename it to EFI of course). Tested to work with DisplayPort with Intel HD 4600. This model doesn't have HDMI, so can't confirm if it'll work. If you have an Nvidia or AMD card, it'll need to be remove. Set the BIOS to default. Apply and set SATA Operations to AHCI and Boot Option to UEFI. Once you're able to get to Clover GUI, hit F4 to export the raw files. Compress /EFI/Clover/ACPI/Origin and attach it here. I'll try to patch the files for you. Optiplex3020_EFI.zip

you will get output after the last command recreating the cache.

run permission fix and paste the output here sudo chmod -Rf 755 /L*/E* sudo chown -Rf 0:0 /L*/E* sudo touch -f /L*/E* sudo chmod -Rf 755 /S*/L*/E* sudo chown -Rf 0:0 /S*/L*/E* sudo touch -f /S*/L*/E* sudo kextcache -Boot -U /

You'll need to copy the patched BDWFB to your installed drive and repair permission.

Looks like your graphics FB is not getting patch on the fly. You'll have to manually patch it and install to /S/L/E

Are the following kext loaded? FakePCIID BrcmPatchRAM2 FakePCIID_BCM94352Z_as_BCM94360CS2 Look under extensions in 'About this mac'

We build ours manually. See here. Then use the bootpack for Z51-70. You can try ypdeveloper or Reema or download from our EDP Bootpack page.

try booting without cache. When you see Clover, hit the space bar and select it from the drop down.

Have you install the patched kext by ypdeveloper?

Set the BIOS to 'Load Default'. Hit apply, then set SATA Operations to AHCI, Boot List Option to UEFI, enable Legacy Rom.

Try this app.

Sure, follow the same process as the SandyBridge system Note1: For Exx20 (SandyBridge models), use Legacy - GUID Scheme. Not UEFI Install Clover with the following settings in 1: Prepare Bootable USB Drive step 26 above: Install Clover in the ESP Bootloader/Install boot0af in MBR CloverEFI/CloverEFI 64-bits SATA

Fn+F3 and Fn+Insert

Did you replace the Kernel with a patch version?

Use DPCIManager.app. See what's showing under Audio Codec ID.

You should get your AppleHDA patched, VoodooHDA does not always work well with HDMI. What is the audio codec ID? There might be a patched kext already made.
