tty.usbmodem not showing up in 1.6.2

Hi Guys

I have just upgraded to from 1.0.5 to 1.6.2 and now I can't see all the tty.usbmodem options under tools-> ports. There is an option in the same menu, called serial ports, but nothing happens when I press it...

I'm running mac osx 10.10

Any idea what I'm doing wrong?
