Arduino Gemma not being recognized

Relatively inexperienced with Arduinos and have been trying to get a Gemma to turn on an led for hours. I am using a Mac with USB 2.0, Arduino 1.6.9, board manager 1.6.12, board is set to Arduino Gemma, I have tried just about every programmer, and have been using the reset button. Also tried using a windows bootcamp as well as different versions of the Arduino program.

I am trying to upload the default setup at this point. The most relevant part of the error message is the following:

Sketch uses 280 bytes (5%) of program storage space. Maximum is 5,310 bytes.
Global variables use 9 bytes of dynamic memory.

    avrdude done. Thank you.
    the selected serial port
    does not exist or your board is not connected

I have no idea where to go from here, and would be absolutely delighted if I managed to turn on an led by the end of the week at this rate. Thank you in advanced
