Hi all I have just updated a iMac 7,2 to sonoma 14.3.1 all upgraded ok apart from Bluetooth, I upgraded my card to a bcm94322mc. WiFi works ok but Bluetooth doesn’t. Any ideas thanks
For bluetooth problems,
This has worked for others and myself to get bluetooth back.
Download Ben Baker's Hackintool.app.
Use the app to edit NVRam (in tool bar) directly.
Look for these/any entries:
bluetoothExternalDongleFailed
bluetoothActiveControllerInfo
bluetoothInternalControllerinfo
Delete each line (using minus button at the bottom of the window) of all BT entries, and wait for the NVRam to refresh itself.
If any of the entries (bluetoothExternalDongleFailed) should come back with values, repeat deleting the entries.
For many bluetooth worked again when the above steps were performed.
Bluetooth settings will show all previously paired devices, and auto connect to them just as before the update.
No Restart Needed.
