OC DELL Latitude E6420

macos monterey 12 works perfectly

i will not talking about the new update macOS Tahoe 26 developer 8 or pubic 4 of 26/08/2025 or 8/26/2025

But with the only problem of the sound in this new, macOS

For me all works 100% except the sound as everyone

But i use Bluetooth and it works

I believe macOS Tahoe is the perfect program for the new Mac family. Anyone who dismisses the software as solely a sound issue underestimates this truly extraordinary program and its team. Anyway, stay tuned for Dortania's new OCPL. This won't happen until the official release in September!

I use Bluetooth speaker and it works

And all work 100% expet sound as everyone !!!

I update macOS Tahoe 26 to the last develper 9

And i use all the method suggested like:

KDK and appleHDA still missed in this macOS

VoodooHDA too

And SSDT audio universal

All these are failled

Because beta 2 is more sequoia but after that the macOS is started to be Tahoe

What is the solution???

Waiting the released version

And Dortania team

Because it is, not the first time that we have sound problem in a new macOS
