Having just upgraded (forced by) my company laptop to a highest spec 13" MacBook Pro (2016+), I have to say that the port to Mac OS is just fine.
Well Done.
Even 2880X1800 runs fabulous!
Sadly my 1.3.x RSS/RO port has a few "scene shift|" issues, but still it seems OK.
I can live it. Let us allow Apple and Unity to figure that one out on their own.
So... Well Done @SQUAD and well done to our RO/RSS pioneers! (I can't fully enjoy all aspects of KSP without you!)
