No valid serial ports for Arduino UNO on Mac
Have you hooked up your Arduino prior to pulling down the tools>Serial Port menu? I only see the port for my Arduino listed when it's actually connected and running. (And it's never one of the bluetooth ports.) I don't have my Arduino with me at the moment so I can't tell you exactly what it is.

Also note that on my MBP (running 10.9.4) I have to be sure to plug the USB cable into the CORRECT USB port. The other port maps to a different port in the list of serial ports.
