Hi, thanks for the great effort on this, I can play TS on macOS without any hassle for a while without messing with wine on my own.
In order contribute I created a Pull Request on Homebrew repository (it's a command-line based unofficial package manager for macOS, widely used) and apparently it just got merged.
So from now on if you have Homebrew installed all you need to do is:
brew cask install cncnet
