Hi,

First of all thanks for the great forum, especially to Rehabman for all his great work, tools and help.

I have a ProBook 6460b, i3-2310M, 8GB, intel only video and 1366x768 screen, with Clover UEFI.
10.11 ran pretty well, with the regular issues.
I decided to upgrade to Sierra after reading a bit and noticed info was a bit scattered.

I pulled it off, except for having the sound working.
Here is a short overview for the ones that are still going to try:
- I used an update guide which I might have misread, or used the wrong one.
Pick this:
https://www.tonymacx86.com/threads/...book-using-clover-uefi-hotpatch-10-11.189416/
and make sure to read everything.
In short: copy kexts to Other folder in Clover, make sure to skip the VoodooPS one, it needs to be the newer version or you will get a kernel panic ( https://www.tonymacx86.com/threads/hp-probook-6460b.203746/ )

- beach ball of death happened when I had not enough kexts in above folder, after reading the upgrade guide here:
https://www.tonymacx86.com/threads/hp-probook-upgrade-to-sierra-hp-probook-4340s.203764/
So make sure the kexts are there

- I had issues with power management after using all the seperately generated ASL files.
I restored the 3 files I originally had and it got back to work

- prefpane issue, worked around as described here:
https://www.tonymacx86.com/threads/solved-trackpad-preference-pane-is-blank.199946/

The remaining issues I have are described here:
https://www.tonymacx86.com/threads/readme-common-some-unsolved-problems-in-10-12-sierra.202316/
They are:
- brightness/hotkeys not working (it says to wait for the source code and use slider)
and the one where my question is about:
- sound is not working.

To repeat what it says:
Some audio codecs will require an additional patch (AppleHDA)

If you are using target codec 0x11d4198b, you may need to also zero out codec compare 0x11d4198a (a new supported codec in 10.12).

eg. in KextsToPatch:
Comment: 0x11d4198a to zero
MatchOS: 10.12.x
Name: AppleHDA
Find: <8a19d411>
Replace: <00000000>

Can anyone point me on how to do that ?
thank you in advance

No need to skip VoodooPS2Controller.kext. The new version is available in the standard place (as per guide).

The set of kexts is fully documented in the Clover laptop guide (linked from the Probook hotpatch guide)...

- I had issues with power management after using all the seperately generated ASL files.

My guide has no ASL files.


A better fix is available (if you look for it), but still researching an easier way...

The config.plist files in the Probook project have already been updated.
 
Hi,

Thank you for your quick reply!
I mean AML files :).
Ah, I missed the relation between the two.
I do understand if every entry needs an AML file match or if it can be in less files.
I'll spend some time to reread and see if I can make it work.

Do you if there is any interest to pickup the probook installer project?
I would be happy to help out and test, I just do not have the time at the moment to drive it.

Thank you again for all the effort and time you spend to help out, it's greatly appreciated!

[edit] I forgot to add that I tried to install with the install_hda script.
In the mean time I added the dict parts with AppleHDA to the config.plist in my EFI partition and rebooted a fee times to no avail.

I do get this message when rebuilding cache:
sudo touch /System/Library/Extensions && sudo kextcache -u /

kext-dev-mode allowing invalid signature -67054 0xFFFFFFFFFFFEFA12 for kext AppleHDA.kext
KernelCache ID: 52EF9C11606AD2876F2DB76071EADA2F
symlink("/System/Library/PrelinkedKernels/prelinkedkernel", "/System/Library/Caches/com.apple.kext.caches/Startup/kernelcache") failed 17 (File exists) <createPrelinkedKernel 2795>

Is that an issue or something that can be ignored?
[edit2] It wasn't really clear which prefpane solution was better, but I could't get the 10.11 one easy.

I have no interest in reviving PBI. My guide works as-is, and I actually like doing things in Terminal instead...

[edit] I forgot to add that I tried to install with the install_hda script.

'make install_hda' does the same as install_downloads.sh.

In the mean time I added the dict parts with AppleHDA to the config.plist in my EFI partition and rebooted a fee times to no avail.

The config.plist files are already updated.

If, after following the guide as written, you have an issue,... read post #1, "Problem Reporting".

Hi vgerris
I have a laptop same your lap
I try install sierra 10.12 but no suceesfull. I can not boot to install sierra
Can you give me file config.plist ?
Thanks vgerris
 
iampro1227 : please check the guide from Rehabman. The config.plist for your model should be working, check the links I posted on where it should be and please leave this post for the original question.

RehabMan, I have simply added the comfig.plist regarding AppleHDA to my existing, compared and see no differences.
I have rebuild the kext cache also without cache loaded and removed the file that gave the error.

I still have the same issue so I attached what I have now according to your guide.
I hope it is ok for me to have the original setup, if not I will try to do it all over again.

I have attached multiple text files in a zip file and the others as requested.
Thank you for all the help!

Your ACPI/patched is incorrect. Follow the guide.

Hi, I am not sure if I understand. I followed pretty much the whole guide, except for replacing that part.
Checked the audio notes, etc.
I tried it and then I had no audio and no battery (so went back to the current ACPI/patched and just got audio not working).
Is it not anything else from the posted files that points to what is wrong?
Can you explain which step of following the guide would fix it?
I would really like to understand better why it would help.

Is there anyone who has audio working on a HP 6460b ?
Please post and let me know.

You must follow the guide completely. Including the ACPI part.

I tried it and then I had no audio and no battery (so went back to the current ACPI/patched and just got audio not working).

It means you made a mistake.

Is it not anything else from the posted files that points to what is wrong?

Your ACPI setup is wrong (as I said), and it is causing your problem.

Is there anyone who has audio working on a HP 6460b ?

If you follow the guide as written, it will work.
