  1. I also had same problem with Quadro2000. Works perfectly with El Capitan and Sierra but same graphical glitches as above with Quadro 2000. I switched to the slightly newer Quadro K2000 and all is fine with Graphics however I can not wake up screen or keyboard after sleep. I gave up on High Sierra and went back to Sierra for now. Hp Z420
  2. Did you make a 10.13 folder and put your 10.12 kexts inside? -apav Hi Jaymack, I just upgraded from El Capitan to Sierra this weekend. I had native sound working(on El Capitan) with Codeccommander however it was causing kernel panic kext on boot on Sierra. Just curious if you are using codeccommander and native sound or are you using voodooaudio for Sierra and High Sierra? I have my Hi Sierra USB made with your help and it boots the installer just fine, I'm just waiting for my new flash drive before going to high sierra, I'd rather not have to convert to APFS after installing on my spinner hd. Thanks for your help. -apav
  3. Thanks jaymack, I'll give it a go and report back! -apav
  4. Hi jaymack That's great! I tried patching using post #921 guide on El Capitan 10.11.6 however I had instability up removing nullcpu kext. Would you mind posting your clover folder with your dsdt, ssdt, kexts, and clover config along with your patched appleintelcpupowermanagement.kext? My z400 config is almost identical to your except I have 18gb ram. I will be attempting to upgrade to Sierra and then High Siera GM this weekend. Thank You! -apav
  5. Does anyone have audio working on El Capitan on a z400? Theres no reason for me to move from Yosemite to El Capitan unless audio is fully working. Thanks
  6. Hi, Do you have audio working as well? Thanks for the great work! -apav
  7. Thanks so much! Working perfectly. I think I understand how to add layout 28 to AppleHDA. Can you explain how/where you added ConfigData in case I need to patch AppleHDA in El Capital in the future? Thanks again -apav
  8. Hi Rockey12, Working! Thanks for the help. When I used your HDEF DST patch and patched AppleHDA, sounds would not work. As per your suggested, I just installed RehabMan's CodecCommand.kext and now sound is working natively in Mavericks!. Can you please help with one more thing - I would like to remove VoodooAudio.kext in Yosemite and have native sound working in Yosemite. In prev post, you mentioned I have to patch AppleHDA for Yosemite. Can you please help me? Thanks for your help! -apav ****Update I now have native audio working on Yosemite 10.10.4, but only through "line out" rear. I used MacPeet's AppleHDA_Yosemite_ALC262_HP_Z800_004 from post #24. I added "layout28.xml.zlib" & "Platforms.xml.zlib" to his patched AppleHDA from Rockey12's "Apple HDA262 Mavericks 10.9.5" patched AppleHDA I am not able to play sound through the headphones, it's not an option in settings -> output See attached screenshots. Do I need to make any changes to Info.plist? Any help would be great appreciated. Thanks! -apav
  9. I haven't been able to get native sound working but I have not been able to put to much time into it. I will try again soon and let you know.
  10. Hi Rockey12, I am having trouble with your HDEF patch. First, it was saved as .rtf I converted to plain text ".txt" but I am having trouble apply the patch in both DSDT editor and MaciASL Can you please help? Thank you -apav
  11. Hi Rockey12, Did you have a chance to test this yet? apav
  12. What are the advantages to using clover in the HP z400 / 600 / 800 vs chameleon? -apav
