@jarombra Glad to hear you are on your way to developing with c# and RhinoCommon!
Yeah, this is a pain point that will be resolved eventually. @dan and @Alain might have some ideas of when a more useful c# component might be available in Grasshopper for mac.
In the mean time, you can check out our developer resources, which explain how to get started creating your own plugins with Visual Studio for Mac.
You could perhaps create a simple plugin with the rhino add-in for visual studio for mac (one of the steps in the developer docs for mac), and try out code there with all the nice features like intellisense, etc.
