2.2 Arduino Hardware Driver on OSX

On OSX platform, you don't need install any driver. OSX has already recognized your Arduino board. You can verify it on Terminal.

You should serial port information of Arduino board on Terminal, for instance, I have detected Arduino board on /dev/cu.usbserial-AE019521.
