no panic.

Same problem on intel ax211 - bluetooth not to enable.
I think there are two points here.:

• lack of explicit indication of the OS version in the code
• another USB initialization system in macOS 26

I have the same issue, bluetooth of AX210 not working now, I have tried many ways

[thehappyboy]

reboot your mac， and reset nvram from the boot options

[beelzebozox86]

reboot your mac， and reset nvram from the boot options

That doesn't work.

[thehappyboy]

1. add the bluetoolfixup settings.
   ref :https://github.com/acidanthera/BrcmPatchRAM

7C436110-AB2A-4BBB-A880-FE41995C9F82:bluetoothExternalDongleFailed — 00
7C436110-AB2A-4BBB-A880-FE41995C9F82:bluetoothInternalControllerInfo — 0000000000000000000000000000

2. nvram from the boot options

[beelzebozox86]

bluetoothExternalDongleFailed — 00

Yes, already have that UUID defined like that, along with:
BlueToolFixup - The version you linked 2.7.1.
IntelBlueToothFirmware
IntelBTPatcher

[davidtran1010]

try all above approachs, still not working

[thehappyboy]

I think your usbmap.kext or usbports have some problem, so the opencore can not recognize bluetooth device. you sould remap the usb ports, the bluetooth usb port should be internal(type 255),reload the kext, then everything will be ok

...usb port should be internal(type 255),reload the kext, then everything will be ok

Before posting guesses and hints, please review the logs and system messages above if they mean anything to you. There's no need to write everything; if a question is asked here, it means the case can be reproduced. Reproduce it and post the results, otherwise your advice is meaningless.

Hello. 🙂
Currently, Intel Bluetooth is not working on macOS Tahoe 26 because the maximum kernel version value for IntelBTPatcher.kext is Sequoia.
When I modified KernelVersion::Sequoia from IntelBTPatcher.cpp to KernelVersion::Tahoe with Xcode, compiled and built it, and applied it, Bluetooth worked well.

Of course, BlueToolFixup.kext must be the latest version, and the BluetoothExternalDongleFailed, Bluetooth InternalControllerInfo NVRAM values must be applied, as in the comments above.
And, USBMap.kext must also be modified for macOS Tahoe 26 version, and the connector type of USB port connected to Bluetooth must be Internal(255).
Additionally, if you changed SMBIOS while upgrading to macOS Tahoe 26, you must also modify the SMBIOS value in USBMap.kext to the changed model.

You can download the modified Intel Bluetooth Kexts from my GitHub repository below.

Note

The process of installing this Kext on macOS Tahoe 26 is the same as on macOS Sequoia 15.
For Monterey and newer, please read the instructions.

This is absolutely the fix. I have Bluetooth working as well in macOS 26.1.

Thank you for this.

[davidtran1010]

I has my audio output now with my airpods, but input not show device. do you guy meet this error?

[SerjNIX]

Bluetooth worked well.

Great. Works to. Thanks!
