Please see attached.
Ofcourse I erased MLB, Serial Number, System UUID and ROM entries.

Also the AMD power gadget kexts are missing as I deleted them since they were not working (but were the latest ones available).

You don't seem to have a UTBMap.kext?

You need that in addition to USBToolBox.kext so the mapping of your ports actually happens..

UTBMap.kext doesn’t work with macOS Tahoe, as it has the old port number and type naming format. Tahoe requires the new naming format introduced by Apple when Tahoe was released.

USBMap.kext or USBPorts.kext are both better options for macOS Tahoe, as they both incorporate the new and old naming conventions required for macOS Catalina through to Tahoe.

So the UTBMap.kext + USBToolBox.kext combo is no longer valid?

Those two kexts work in macOS upto Sequoia, just not in Tahoe. They need to be updated for Tahoe compatibility.

Witam,
Uruchomiłem Tahoe 26.3 MOBO: Gigabyte B550 Gaming X V2 ver. 1.3, CPU: Ryzen 7 5700X, GPU: Radeon RX 570 4 Gb VRAM, disable GPU Intel ARC B570, RAM: 64 Gb RAM Ripjavs V XMP2 4000 MHz. Dźwięk działa tylko po HDMI, jakość okropna. Porty USB działają.

AppleALC.kext doesn’t work in Tahoe, due to Apple removing the AppleHDA.kext from the OS. You need to add AppleHDA.kext to the OS, so AppleALC.kext will work with your builtin Audio Codec. See the GitHub page linked below.

GitHub - perez987/AppleHDA-back-on-macOS-26-Tahoe: Reinstall AppleHDA.kext, removed since beta 2, in macOS Tahoe to restore sound from the built-in audio chip.
