I just wanted to mention a small development that some you of might appreciate.
We've successfully built and deployed plugins for MOD using Windows. (for MacOS it should work just the same)
We did this using Docker Toolbox, which gives us a Linux command-line interface but without having to mess up with virtual machines directly.
It's still running inside a virtual machine, but all the configuration and setup are automatically done for us.
We also made a docker image of mod-plugin-builder, available directly upstream.
This way you don't have to do the boostrap process, you can just import the online docker image.
We have this documented in our wiki.
Comments and questions are very welcome!
