Hey, I think they didn't make havok for mac OS X, and they probably never will.
I hope they do eventually make it, because shockwave is completely pointless without havok, but I don't think they'll ever make it, because they made a new Xtra that will be used in most new games instead of havok, but mac OS X will still never be able to play the old games
I hate adobe so much for doing this
In Mac OS X you can find the folder under Library > Application Support > Macromedia> Xtras.
In order for an Xtra to be downloaded by a movie, the Xtra package must be made available for download at a URL. Once a movie has downloaded Xtras into the Shockwave Xtras folder, the Xtras will reside there permanently (newer versions can be downloaded to overwrite older versions, however).
A number of the most commonly used Macromedia Xtras are included in the default Shockwave Player installation. This allows most content authored in Director to be viewable in a default Shockwave installation without requiring any additional Xtras to be downloaded.
When the movie is run, either in the Shockwave Player or as a projector, it will check the user's Shockwave installation to verify what Xtras are installed and will prompt the user if an Xtra will be downloaded.
Hope this helps.
Havok was dropped in D11 and replaced by Ageia. Havok still works in Shockwave on a PC via the special backward-compatibility version of SW10. There is no such thing for Mac SW11+, thereby killing off Havok content for Shockwave on the Mac.
