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

davidtran1010 avatar Sep 28 '25 02:09 davidtran1010

reboot your mac， and reset nvram from the boot options

thehappyboy avatar Sep 30 '25 02:09 thehappyboy

reboot your mac， and reset nvram from the boot options

That doesn't work.

beelzebozox86 avatar Sep 30 '25 21:09 beelzebozox86

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

  1. nvram from the boot options

bluetoothExternalDongleFailed — 00

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

beelzebozox86 avatar Oct 01 '25 02:10 beelzebozox86

try all above approachs, still not working

davidtran1010 avatar Oct 01 '25 13:10 davidtran1010

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. https://github.com/lshbluesky/IntelBluetoothFirmware

[!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.

Works beautifully, and I see that the LE mods already incorporated into it. Thank you so much. Much appreciated!

Still not working for me on Tahoe, I used these kext https://github.com/lshbluesky/IntelBluetoothFirmware + BlueToolFixup.kext, added NVRAM keys, but nothing. I'm trying to connect Logitech M196 Mouse. Thank for the help
