Small follow-up regarding the AX210 Bluetooth BCM_4350C2 fallback state:

 

I was able to recover my AX210 Bluetooth side under macOS 26.5.2 and macOS 26.6 beta 4 after it had remained stuck in a persistent BCM_4350C2 / Address NULL / State Off state directly after the 26.6 beta 4 update. 

 

The interesting part is that the BCM_4350C2 state was still visible even after disabling IntelBluetoothFirmware, IntelBTPatcher, BlueToolFixup and AirportItlwm, and even after physically disconnecting the AX210 Bluetooth USB cable. With only Lilu loaded and no Intel 0x8087 USB Bluetooth device present anymore, System Information still showed the stale BCM_4350C2 / UART / Address NULL Bluetooth controller. At that point, this could no longer have been the real AX210 USB Bluetooth device, but looked more like a persistent macOS IOBluetooth ghost controller.

 

The recovery path that finally worked was:

 

1. Temporarily reinstall BCM943602CDP.

2. Boot the native Broadcom/OCLP EFI.

3. Let macOS initialize a real Broadcom Bluetooth controller.

4. Shut down and remove power.

5. Switch back to AX210.

6. Boot again with IntelBluetoothFirmware 2.5.1, IntelBTPatcher 2.5.1 and BlueToolFixup 2.7.2.

 

After that, AX210 Bluetooth came back as THIRD_PARTY_DONGLE again:

 

Address: 20:BD:1D:D8:94:32

State: On

Chipset: THIRD_PARTY_DONGLE

Firmware Version: v12490 c12490

Transport: USB

 

Magic Keyboard and Magic Mouse are connected again.

 

So this is not a code fix, but at least in my case temporarily initializing a real Broadcom Bluetooth controller cleared the persistent BCM_4350C2 ghost controller state, while NVRAM reset, deleting Bluetooth preferences and long complete power-off alone did not.

I succesfully installed Tahoe 26,6 on Dell Optiplex 7090 MFF, Intel cometlake core i5 10400, intel uhd 630, 16gb ram.

The systen is responsive but i haven't audio (alc3246), QE/CI, Wifi and open core gui.

No patches installed

@cavallo Audio won't work in macOS Tahoe without taking additional measures.  Wi-Fi depends on whether it's Intel or Broadcom and what chipset.  It sounds like this must be your first macOS Tahoe installation on a hackintosh.  You may want to install macOS Sequoia first (where your audio should be easier to address) and then upgrade to Tahoe after everything is working the way you want it to.

 

If you need more help than that, this isn't the ideal help thread for you and is primarly where we're reporting success and possible issues with the Tahoe Beta release.  I think It would be best for you to create a new thread where you can solicit help.

 

EDIT: @cavallo Maybe I misunderstood - you are asking for help - correct?

you are right. thank you. I don't undestand how is possible that i have 2 pc asus ht110 based where Tahoe has qe/CI but no audio and wifi.

Sequential OTA update (1.44 GB) from macOS 26.6 beta 4 (25G5057c) to macOS 26.6 beta 5 (25G5065a).

Apple has not yet released a Kernel Debug Kit for macOS 26.6 beta 5 (25G5065a). OCLP correctly selects Kernel Debug Kit 26.6 build 25G5052e, corresponding to macOS 26.6 beta 3, as the closest available match.

My Broadcom/OCLP setup (BCM943602CDP) works under macOS 26.6 beta 5 as expected. AppleHDA, Wi-Fi, native Bluetooth, AirDrop, AirPlay, Screen Mirroring, Continuity Camera, Personal Hotspot, and sleep/wake all appear to be working properly.

 

My Intel/OCLP/AirportItlwm setup (AX210) also works under macOS 26.6 beta 5 as expected. AppleHDA, Wi-Fi, Bluetooth, AirPlay, Screen Mirroring, and sleep/wake all appear to be working properly.

 

Nevertheless, immediately after the update to macOS 26.6 beta 5, Intel Bluetooth once again fell back into the same broken state previously observed following the beta 4 update. As with beta 4, Bluetooth functionality on the AX210 was fully restored only after booting once with my Broadcom EFI and BCM943602CDP to perform a hardware reset, and then switching back to the Intel setup. I had already been able to restore Intel Bluetooth under beta 4 afterward using exactly the same procedure. This strongly suggests that the issue is not a general incompatibility with macOS 26.6, but rather a persistent controller or firmware state triggered by the update process.
