Any idea why it's not showing up on my rMBP?
I'm using a bluetooth module from an A1181 Macbook C2D.
The bluetooth module says A1114, and is recognized as plugged in in bootcamp, but as an unrecognized device. OS X shows no hint of it.
In case anyone is still thinking about doing this mod, mine stopped working reliably after I upgraded to Mavericks. I would either drop my track pad connection or the keyboard would not work. After switching to the recommended iogear dongle things are working fine.
