I recently got all nostalgic and loaded an old favourite Duke Nukem( Manahatten Project) onto I mac ( 2010) ..running OS Sierra 10.13.6 and I am using a PS5 dual shock controller which is recognised by the I mac BUT wont work with the game. I have looked on many sites to gain some insight as to activate the controller with the game ?? I have tried to get info from any help duke nukem sites but no luck yet . FYI The keyboard works OK with the game.
