Setting up EPG Data with a Mac

I have a Mac with an EyeTV tuner which I use for my OTA channels. I want to use Kodi installed on my two Amazon FireTV to watch and record those programs. I’ve successfully installed Kodi on both FireTV s and can receive the channels for viewing using the IPTV Simple client Add-on. Now I’m trying to set up the EPG data, and am having no luck. I can’t even figure out how to start. Most of the pages I read go over my head. It looks like the only way I can get something to possibly work is using a program with line command functions in terminal, which I’ve done before, but I can’t get to the point of installing those programs. I tried http://mc2xml.hosterbox.net, and downloaded the Mac version, but it’s just a file, not an installer, and I don’t know what to do with it to install it so I can use the command line functions to (as I understand it) create an xml file which will give me my listings. I’m actually not sure if I need to create a file, or if there’s a website I can just paste into the EPG preference of the IPTV plugin which will give me my local channels.

I’m obviously pretty out of my league here, so any help is appreciated.
