Arduino Pro Micro doesn't show up in Tools > Serial Port

Hey,

I bought an arduino pro micro not long ago and from the get go i haven't been able to upload any sketches. I have downloaded all the necessary files from Sparkfun and the board shows up in Tools > Board.
All that shows up in the Tools > Serial Port menu is:

/dev/tty.Bluetooth-Incoming-Port
/dev/cu.Bluetooth-Incoming-Port
/dev/tty.Bluetooth-Modem
/dev/cu.Bluetooth-Modem

When i plug in my Arduino Uno (Which works fine) the Serial Port:

/dev/tty.usbmodem1421
/dev/cu.usbmodem1421

Appears. These are the ones i use to upload sketches to that board, but none of the others worked on either board.
If its any help, i am using a Mac with OSX 10.9.2.

Any help to get my board up and running would be greatly appreciated.
Thanks
Isaac
