Thanks for that info. I’m assuming MSVS C++ will be needed eventually before prime time, indeed, it may make sense to pick up a skookum PC for my code development now. My OP was really more focused on whether what I was seeing was an anomaly (which it clearly is) or if the Mac was even possible, development of course, but end user ability to use our product was at least as important. When we first started this seriously (back when we bought Unity 3.x (then 4.x, then 5.x :() we had passed over UDK at that time to avoid a Windows-centric product release. It seems like UE4 solved that.
Really appreciate all the replies.
