Why won't my iMac recognize my Mega32u4 Arduino Pro Micro board (I've tried several cables)?
From what you say here:


  I plug it into my iMac and open Arduino and go to the board tab, and it doesn't even have a Pro Micro choice, so i just choose Micro.


and from the dump you provide:


  Arduino: 1.6.9 (Mac OS X), Board: "Arduino/Genuino Micro"


It looks to me like you're selecting the wrong board. Instead of just picking a "similar" board from the Tools menu, what you should do is add the Sparkfun board manager package and then select the Pro Micro from it.

Here you can find the procedure step by step. Follow it and you should be all set.

EDIT:

If you tried to upload a sketch with a wrong board selection, then your your Pro Micro may have become "bricked". In order to unbrick it, follow this procedure (same link as above, different section).

Once you unbrick it, upload the specific blink example code for Pro Micro that you can find in another section of the same link.

If it keeps not working, READ THE ENTIRE ARTICLE linked and try out all troubleshooting instructions before anything else.
