I have a 3.3V Sparkfun Pro Micro and I am trying to run the example Blink sketch. When I attempt to upload the sketch, I receive the following error:
Arduino: 1.6.5 (Mac OS X), Board: "SparkFun Pro Micro, ATmega32U4 (3.3V, 8 MHz)"
A lot of lines from compilation*

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
I am completely new to Arduino as of a little over a week ago so I don't have a very good understanding of the programming aspect of using Arduinos, much less troubleshooting techniques. Does anyone know how to address this error? In addition, the serial port for my board (Sparkfun Pro Micro) does not always appear when I connect it to my laptop (MacBook Pro). I already had to download an older version of Arduino in order for these particular USB drivers to work but is there something else I need to do to ensure I don't have to restart my computer every time I want to connect?
