I own a Macbook running OS X 10.10.3 (Yosemite)
I own a Min Seg.
My Min Seg model is built on an Arduino Mega 2560.
When I connect the board to the Macbook,
using either of the Macbook's two USB 2.0 ports,
using either of two USB A to B cables,
the board lights up, but I am unable to connect
to the tty device using the Arduino IDE.
Tools --> Port offered:
/dev/cu.Bluetooth-Incoming-Port /dev/cu.Bluetooth-Modem /dev/cu.usbmodem621 (Arduino Genuino Mega or Mega 2560)
I was expecting to also see:
/dev/tty.usbmodem621 (Arduino Genuino Mega or Mega 2560)
If I unplug the board, the third listed option
Tools --> Port disappears, as expected.
I opened the System Information utility application.

I used the Sparkfun Terminal Basics wiki to check for the device. I used the Terminal utility application.

I tried several means from here:
I also attempted to connect through Mathworks Simulink.
When setting connection options, the program states
that a cu device is expected, rather than a tty.
