From what I understand, this is hard-coded to use windows. There are methods you have mentioned to get it to run on a Mac but I don't believe there are currently any plans to get it to run on a Mac. This would require a rewrite much like the one OBS currently has going on.
(Please Note: I only have basic knowledge of programming so what I have said should be taken with a pinch of salt regarding the rewrite)
Sorry,
