Interactive fiction on the mac, is it posible?

Hello, I enjoy Interactive Fiction so much, but since I have a Mac system I haven't played any game. I used to enjoy these games, specially glulxe ones, which include some multimedia. The problem is that the few glulxe interpreters existin for the Mac, like Zag, are unable to deal with the multimedia files, making the game half-enjoyable. Do you know any good interpreter, or do I have to switch to Windows to play? Regards
