Spherical crashed back in... 2013 I think? and we lost everything. The forums were pretty dormant for a while... then minisphere happened. It's... still pretty dormant here... but at least we now have an awesome new engine to show for it?
By the by if you want to maintain a macOS port that's fine--I don't have a Mac so I can't practically support the platform. I don't know which build you compiled though; for now I recommend using the 4.3.8 release (Git tag v4.3.8) as the current git master is under heavy development and may have some things broken.
