DW1550 Wifi works but Bluetooth doesn't on macOS Sequoia

[osx.9xbrn]

Hi,

 

I'm trying to get Bluetooth (DW1550) working on macOS Sequoia 15.5 on my E6440. I followed Wifi in Sonoma & later: Patching for legacy Broadcom wireless cards and got WiFi working. However, BT shows up in system information but won't allow me to toggle it on from the menu bar.

 

 

 

 

EFI.zip

 

 

For context:

- Install macOS using system product name MacBookPro15,2

- After initial device setup, reboot and reset NVRAM

- Boot using system product name MacBookPro11,1

- Run OCLP to fix graphics and networks

 

Any idea what I'm missing?

Hello, it's been some time since I last used a non-Apple Wifi/BT card but I noticed the 2 following elements in your OC config file.

• You don't inject the Bluetooth injector kext, having limited this to macOS Big Sur (20.9.9). Are you certain you don't need it? The BT chip used on the DW1550 is clearly present in the injector:

1.         <key>413c_8143</key>
           <dict>
               <key>CFBundleIdentifier</key>
               <string>com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport</string>
               <key>IOClass</key>
               <string>BroadcomBluetoothHostControllerUSBTransport</string>
               <key>IOProbeScore</key>
               <integer>3000</integer>
               <key>IOProviderClass</key>
               <string>IOUSBHostDevice</string>
               <key>idProduct</key>
               <integer>33091</integer>
               <key>idVendor</key>
               <integer>16700</integer>
           </dict>

 

• What does this NVRAM property do?

BlueToolFixup replaces BrcmBluetoothInjector for macOS 12+. According to their docu, BlueToolFixup also supports 413c:8143 devices.

 

Both bluetooth* NVRAM properties are from the same page. Others suggested it worked for them with DW1560 cards so I thought to give it a go, but it's doesn't work for me.
