the minimum version in the info plist is

  "LSMinimumSystemVersion" => "10.14"

I have a mini running 10.13.6, I can update the MimimumSystemVersion to 10.13.6, but 

Is this intentional?

Yes this is intentional as per the Release notes

Code:

The minimum OS required for Kodi on macOS is now Mojave (10.14). This was done to allow the project to continue using more modern C++ 17 features. macOS Mojave was released on 24th September 2018 and hardware supported can be seen at Apple.com.
