[Q] Connecting Kodi on Fire TV to Mac on the Same Network topic

How do I go about connecting Kodi on my FireTV to my Mac on the same network? I'd like to back up Kodi and save the backups externally on my Mac, but I'm not sure how to access my Mac from the Fire TV. For example, when I go to the "Install from Zip File" window, I don't see any references to my Mac's hard drive listed in the sources there.
