it's kind of a hack but it's simple and straightforward. (just tested it successfully 2 minutes ago)
1 Open First wwise as usual.
2 locate the Wwise.app application and RIGHT clic on it (or control clic if your mouse has only one button and you come from the past) A dropdown menu open, click, show package contents.
3 navigate to Contents => MacOS
4 double click wwise2016, it will open the terminal and the terminal will open a new instance of wwise.
5 kick some funky tunes in this game and worship me
6 You are welcome.
