NetHack 3.6.0 was released in Dec 2015. An official binary is available for Mac OS X, but it's terminal-only.
NetHackCocoa, which has brought so much joy to so many, has, alas, not been updated since 2012 as far as I can tell.
Is there any way to play NetHack 3.6.0* using a tile set on Mac OS X?
* An optimist might say "NetHack 3.6.0 or greater, but that seems awfully optimistic.
