AppleHDA.kext macOS 26 Tahoe beta 3 MyKextInstaller /Libreria/Developer/KDKs/KDK_26.0_25A5279m.kdk/System/Library/Extensions

 

Ho provato a usare il metodo MyKextInstaller, ad estrarre il kext KDK e a installarlo come facevamo prima quando usavamo Chameleon o Clover (che bei ricordi), ma senza successo, il sistema continua a riavviarsi.

 

Non so se è il modo corretto e semplice per farlo e, se tutto il resto fallisce, come posso rientrare nel sistema senza dover reinstallare o installare da zero.

 

L'ho provato su un SSD USB e non ho avuto altra scelta che installarlo da zero. Quindi ho provato a far sì che l'USB si riavviasse e potessi installarlo.

I don't know if it's the correct and simple way to do it, and if all else fails, how can I get back into the system without having to reinstall or install from scratch.

Start in recovery mode and in the terminal type the following: 

mount -uw /Volumes/Tahoe
bless --mount /Volumes/Tahoe --bootefi --last-sealed-snapshot

Rename 'Tahoe' to the name of the disk where you installed macOS Tahoe.

Bingo !!!

 

After rebooting, the green screen appeared, but only for a few seconds,
then it continued to boot, displaying the Welcome screen again 

 

... AppleHDA restored and working ... Congratulations !

Starten Sie im Wiederherstellungsmodus und geben Sie im Terminal Folgendes ein: 

 

Benennen Sie „Tahoe“ in den Namen der Festplatte um, auf der Sie macOS Tahoe installiert haben.

Brauchst du es?
Hier ist es:AppleHDA.kext.zip

Hello friend @Mirone
 

You're truly a great developer, kudos for your work on the MyKextInstaller.app.

 

The sound now works after installing the AppleHDA.kext (4.5 MB) with your MyKextInstaller.

I first installed the KDK as instructed, then the message "Copying KDK" appeared (which wasn't visible in your previous app version), and then a backup of the original AppleHDA was created. I assumed some frameworks were still needed, which isn't the case, is it?

 

Then finally, the decisive attempt with a restart came, and the sound came from my internal speakers in my late 2013 (27-inch) original iMac. My late 2023 iMac has a Cirrus Logic sound chip  Realtek ACL892.

 

You managed to restore the sound with AppleHDA, which wasn't possible with the Dortania OCLP 3.0.0 nightly and with my Chinese friend labobamac's OCLP mod.

 

Thanks again for your work. Is there any way I can reward you with a PayPal donation or something similar?

I'm glad you have some luck in life, I've never done anything here with the intention of raising any money, but if you feel happy to buy me a beer here's this link: Pay me a beer.

@Mirone needs to update it. Unless you want to do it manually.

 

For those who like to do things manually, here is my procedure 😀....

 

Boot to Recovery Terminal.  Revert System to Last Sealed Snapshot... 

-bash-3.2# sw_vers
ProductName:        macOS
ProductVersion:        26.0
BuildVersion:        25A5306g
-bash-3.2# nvram csr-active-config
csr-active-config    %03%08%00%00
-bash-3.2# mount -uw /Volumes/Tahoe
-bash-3.2# bless --mount /Volumes/Tahoe --bootefi --last-sealed-snapshot
-bash-3.2# reboot

 

Boot to Tahoe
1) Delete /Library/Developer/KDKs/KDK_26.0_25A5279m.kdk and re-install it (to get clean slate)

Spoiler

FreshInstallKDK.thumb.png.dd73d9d3a71a06f4bbd09265d2377420.png

 

2) Use Finder to copy /Library/Developer/KDKs/KDK_26.0_25A5279m.kdk/System/Library/Extensions/AppleHDA.kext to the desktop

Spoiler

AppleHDAinSLE.thumb.png.bdebc529e43dcbce7c7f40ab99174ff5.png

 

3) Open Terminal app.  

a) Check SIP is disabled and use kextstat to determine which kexts are loading eg AppleALC will be present but not AppleHDA... 

fusion71au@fusion71aus-iMac ~ % nvram csr-active-config

b) Mount the root volume (in my case disk1s4) as r/w @/System/Volumes/Update/mnt1 (if the folder isn't already there, make it with the command sudo mkdir /System/Volumes/Update/mnt1), merge /Library/Developer/KDKs/KDK_26.0_25A5279m.kdk/System into /System/Volumes/Update/mnt1/System with "ditto", copy over AppleHDA from desktop to SLE, use "kmutil create" to create new System/Boot/Aux Kernel Collections, then bless + create new snapshot...

Check with Finder that the new KCs are installed at  

/System/Library/KernelCollections/BootKernelExtensions.kc
/System/Library/KernelCollections/SystemKernelExtensions.kc
/Library/KernelCollections/AuxiliaryKernelExtensions.kc

Thanks to @laobamac_yyds who first made the process available with OCLP-Mod, @LockDown for discovering the "secret sauce" command to rebuild KCs and @Mirone for his new simple kext installer for Tahoe.

Yes, I think now we’re going to have a dedicated thread. I just need to fine-tune a few adjustments in MyKextInstaller and gather some testers you're on that list... LOL. Then I’ll open a dedicated thread for MyKextInstaller.

Thanks to @laobamac_yyds who first made the process available with OCLP-Mod, @LockDown for discovering the "secret sauce" command to rebuild KCs and @Mirone for his new simple kext installer for Tahoe.

 

 

basically if we still use 25A5279m KDK we dont need to copy AppleHDA.kext back to  SLE because with  

sudo ditto /Library/Developer/KDKs/KDK_26.0_25A5279m.kdk/System /System/Volumes/Update/mnt1/System

it will copy All the System Folder from KDK to destinated location 

 

please note that for system can't boot well with beta 1 will be affected, because with this kdk restore all the kext will be back to beta 1 kext .  because there is no new KDK yet for beta 2 and beta 3 .. CMIIW

 25A5279m KDK includes AppleHDA on a fresh install of KDK?

What i noticed is, on a fresh KDK install, it does not include AppleHDA.

But once you ROOT PATCH > ditto KDK to /S/L/E > copy AppleHDA to /S/L/E > Update Cache > restart

AppleHDA will now be in /Library/Developer/KDKs/KDK_26.0_25A5279m.kdk/System

 

At least that what i observed.

 

UPDATE: it is there all along 😃

@Mirone

 

I've tested version 3 of MyKextInstaller to get back the motherboard's ALC1220 audio.

Everything seems to have worked fine from the app.


With great appreciation for @laobamac_yyds 's work (not tried yet), MyKextInstaller seems like a simple method for accomplishing this task. At least on my system, it worked as expected.


Notes (nothing new, just commenting from my own experience):

  • The app doesn't run with Gatekeeper enabled; I disabled it with Sentinel.
  • SIP disabled: I have 03080000 but, following @deeveedee, 01000000 may be enough, which only allows untrusted kexts. (he was referring to VoodooHDA).
  • KDK (version 25A5279m) may have been previously installed, MyKextInstaller detects it correctly.
  • I downloaded AppleHDA.kext from this thread (you uploaded it), and my question is: if AppleHDA.kext isn't available, do I have to run commands to extract it from the KDK? Sorry if what I'm asking has already been answered (I'm sure it has) but I'm having trouble finding it. -> Silly question. I see it's available in /Library/Developer/KDKs/KDK_26.0_25A5279m.kdk/System/Library/Extensions/AppleHDA.kext.

Thanks for your work.

@miliuco  Setting csr-active-config=<01000000> is enough for VoodooHDA.kext AFTER it is installed into /Library/Extensions with csr-active-config = <03080000>.   It would be interesting to see if the AppleHDA.kext fix still works after setting csr-active-config = <01000000>.  I thought that the AppleHDA patch required more disabled integrity protections, but I haven't tested it.

@deeveedee

Thanks for the clarification. I remembered reading your post, but I associated it with recovering AppleHDA.

You are all publishing so much information that it's hard for me to follow you 😂

I'm crossing it out in my post.

@Mirone

I'm in too. I'd like to learn about the app's code. It might be available on GitHub or similar sites. Think about it 🙂

Forgive my ignorance. OCLP nighty build has this contribution. But what is PSPKG?
 

 

 

Hello, I have installed AppleALC.kext. After rebooting, it won't boot. What should I do?

How did you install AppleALC?

It is in S/L/E, it’s wrong. 
Look for how to boot —last-sealed-snapshot on Recovery to get back to a working system. 

 

 

I booted into sequoia and entered -S -X and successfully booted into tahoe and installed AppleHDA.kext by pulling it from KernelDebugKit and installing it using MyKextInstaller. After that, I removed -S -X and tried rebooting again, but there was still no sound. PS. I installed it wrong. I pulled it from EFI AppleHDA.kext.

Dont make it complicated.

Revert to sealed snapshot. Restart. Run mykextinstallerV3. Done

No need to install AppleHDA yourself

I tried doing what you suggested but there is still no sound. Thank you.

Hi everyone, how are you?
First of all, sorry for the OT. I’ve updated MyKextInstaller with the following improvements:

  • You can now restore the last sealed snapshot
  • In addition to Kexts, it's now possible to install .bundle files
  • Some minor internal code improvements

There are still some improvements to be made regarding the app’s interface.

Any volunteers to test it?
