Arduino Nano not found on Macbook Air

I am completely new to Mac, so forgive me if there is a simple fix I am overlooking. I have installed the Arduino IDE from the and 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 appreciated.
