It may be simpler and more consistent with the UI expectations for your 
  users to just use a collapsable panel with a disclosure triangle 
instead.  In most cases where an OS X drawer would work a collapsable 
panel will work just as well, and the convention is universally accepted 
on all modern platforms (even OS X).
