As there are no binaries for the Mac platform, I had to compile the sources on my own.
It fails. OSX 10.10.5, Unreal 4.9.2
In SceneProviderCommand.h we have a forward declaration of ADungeon, but the template AddActor fails with this line:
MoveToFolder(Actor, Dungeon->ItemFolderPath);
(member access into incomplete type ADungeon)
