I am new to Mac, so forgive me if there is a simple fix I am overlooking. I have downloaded the latest Arduino IDE from arduino.cc and the FTDI driver linked to in the installation guide. The Arduino Nano also works fine with the same usb cable on a PC. The only COM port available is /dev/.cu/.Bluetooth-Incoming_Port which is not my Arduino. In System Information there is a device called USB2.0-Serial which shows up when the board is connected and disappears when it is disconnected. The Link LED on the board also slowly blinks when connected to the Macbook.

Any help is greatly appreciated.
