i tried to run the firmware update and got this error message instead.
This Bluetooth device is not supported.
This computer does not have an Apple Bluetooth module installed. It cannot be updated by this application.
however, i can verify that my bt module is indeed working. it passed the apple hardware test, i've synced my phone through it and i'm using a MacMice bt mouse too.
Can anyone pls advise? I'm on a 12" rev D. Thanks in advance.
