I just bought a new MacPro today ... and it appears that the internal bluetooth antenna may not be connected. It recognizes bluetooth devices only if they are held just a few inches from the back of the case. I'd like to try and resolve this myself so I don't have to pack it all up and take it in for service. I'm looking at the motherboard but can't find anything that looks like an antenna. Can anyone help describe what it looks like or how to get it connected?
