Hack the Amazon Dash Button (JK29LP) on macOS Sierra

Ran into some snafus that might help others.

  1. The homebrew libdnet install didn’t work for me. I followed the install steps on the top answer here: http://stackoverflow.com/questions/40272077/importerror-no-module-named-dumbnet-when-trying-to-run-a-script-that-leverage

2. The MAC address is case sensitive. I think for the Ether interface the convention is for it to be all lowercase. The AmazonConfigureMe page had uppercase.
