I am neither a developer nor an expert in AppleHDA patching, so please forgive me for my rather innocent statement or question.
From my basic understanding, there is a major difference between MyKextInstaller and OCLP-Mod. While MyKextInstaller requires the manual installation of the correct KDK for each user on their respective system (which is prone to errors), OCLP-Mod automatically downloads the correct KDK (without installing it on the system) and processes it internally somehow. Maybe @laobamac_yyds could provide further details in this regard. I’m completely fine with OCLP-Mod anyway and I never witnessed any disappearance of macOS Apps after my OTA Updates of Tahoe.

 

Regarding the frequent minor macOS beta updates, I personally prefer to stay with a more stable and secure release whenever possible and thus avoid updating my system every week. There are usually very few changes in these small macOS beta versions anyway, so I’m perfectly happy just reading about everyone’s success each week.. 😉

Guys, if you have any questions regarding MyKextInstaller, please post them in the dedicated thread. I’ll be answering here for the last time about anything related to MKI.

 

MyKextInstaller already automatically downloads and installs the KDK as long as it matches the current system version. However, since Apple insists on never maintaining a consistent standard, when there’s no KDK corresponding to the system version, the user must download it manually.

 

After all, I believe this is the user’s responsibility, not the application’s. That said, I’ve already made some changes in version 1.6 regarding the KDK, and this version should be available soon.

The system crash was not caused by AGDP, but by the loss of connector information.

Upgrade from 26.1 -> 26.2 Beta was easy.  Still waiting for OCLP post-install patches.

Uh, I'm also discussing the Carnations version.It has lost all AMD Support patches, so many graphics cards may crash due to missing connector information.

These cards is native bro. We don't need many things. A good idea is not use Whatevergreen if u have a native card.

For all X299-ers and likely also others..

I executed the recommended commands, but the installation still throws an error. Regards.

 

 

sudo rm -f /Library/LaunchDaemons/com.mirone.MyKextInstaller.Helper.plist

sudo rm -f /Library/PrivilegedHelperTools/com.mirone.MyKextInstaller.Helper

I had the same problem as you; the command didn't work, but completely uninstalling it with an application like "AppeClean" and then downloading and installing it from the creator's website did.

Successfully completed the crack of the limit on the number of XHCI controller 15 ports for macOS Tahoe.

Please disable Kernel -> Quirks -> XHCIPortLimit and load the patch I made.

 

After successful patching:

Patch file download:

 

XHCIPortLimitTahoe.plist

 

Notes:

①If you have installed the old USB environment extension of OCLP-Mod, please use Kernel -> Quirks -> XHCIPortLimit directly and do not use this patch.

②Be sure to disable Kernel -> Quirks -> XHCIPortLimit with this patch

③Maybe this patch will be merged into OpenCore in the future? But so far, there is none. This is the patch I made for BootKC of 26.2B1 using IDA decompilation.

Hi Bro what exactly is the advantage over the 15 port limit apart from having more ports at our disposal?

As I see it the 15 limit works quit well as Apple intended.

 

Forgive me if I'm missing something here as why you deemed the increased limit important or necessary.

Cheers.

To be honest, I don't think this has any advantages because a single controller with 15 ports is already sufficient for me to use.

 

But what's annoying is that many machines lose their USB 3.0 Bus after upgrading to macOS Tahoe and all recognize it as 2.0. After investigating for a long time, it was found that SS and HS were identified as two port bits, because XHCI is backward compatible with EHCI.

 

This results in only the HS* port being injected into these machines But when the 15 port restriction was lifted and SS* successfully recognized again, the 3.0 speed returned to normal.

 

You can compare this picture with above 'after successfully patching' and see that the USB 2.0 Bus has been incorrectly identified.

Para ser honesto, não acho que isso tenha nenhuma vantagem porque um único controlador com 15 portas já é suficiente para eu usar.

 

Mas o que é irritante é que muitas máquinas perdem seu barramento USB 3.0 após a atualização para o macOS Tahoe e todas o reconhecem como 2.0. Depois de investigar por um longo tempo, descobriu-se que SS e HS foram identificados como dois bits de porta, porque o XHCI é compatível com o EHCI.

 

Isso resulta em apenas a porta HS* sendo injetada nessas máquinas. Mas quando a restrição de 15 portas foi levantada e a SS* foi reconhecida com sucesso novamente, a velocidade de 3,0 voltou ao normal.

 

Você pode comparar esta imagem com a 'após o patch bem-sucedido' acima e ver que o barramento USB 2.0 foi identificado incorretamente.

 

 

Thank you

I followed your instructions, but the error persists.
I tried using MyKextsInstaller 1.4 — the process completes, but after restarting, I have no audio.
I’ll wait for version 1.6.
On the last attempt with v1.5, it gave me this error.

 

An error occurred during installation: Unable to resolve dependencies: 'com.apple.driver.AppleTopCaseHIDEventDriver' names a dependency on 'com.apple.iokit.IOHIDFamily', which was not found.

@Fory360 This thread is dedicated to MyKextInstaller and is the best place for you to ask your questions.  You may also want to look at this thread which discusses OCLP-Mod, an alternative to MyKextInstaller.
