Hi all,
a few days ago i found a way to play SH4 on a mac,
Only thing you need is the Silent hunter on a CD and this website:
http://www.paulthetall.com/ Go to game ports > Simulation games > Silent hunter 4 > download the wrapper > watch to movie and install the game.
For me it did real work, i hope for those who try it that it also works.
Greetings me.
