Hi Graham,

Let's start with a copy+paste from the Docs

"HOW TO respond to quitting an OS X application

On OS X systems, the ?Quit? menu item is part of the
Application menu, which is displayed by the operating
system rather than by the application. Because of
this, choosing ?Quit? on OS X systems does not send a
menuPick message, so you cannot handle quitting in a
menuPick handler.

Instead, choosing ?Quit? sends an Apple Event (class
?aevt?, ID ?quit?) to the application. If you don?t
intercept this Apple Event in an appleEvent handler,
Revolution sends a shutdownRequest message in response
to the Apple Event. To respond to the user choosing
?Quit?, handle either of these messages.

  Tip:  For easiest cross-platform development, place
all the code you want to execute on quitting in a
shutdownRequest handler."

On MacOS X, the app-bundles are actually folders,
containing the "real" application and lots of other
things that "Classic" MacOS would have stored in the
resource fork and other places.
The bundles allow for one easy spot to store
everything that belongs with your applications, so you
don't need to find DLL x here, VBX y there, etc. as
you would on Windows machines.

Admittedly I didn't have mluch luck with Rev 2.1 on my
MacOS 9 iMac, either : upon install it crashed ; it
qworks fine, but I can't use the Distribution Builder
to create applications.
So for now I create my Classic apps on the MacOS X
PowerBook, and that works ; when 2.1.1 final rolls
around, I'll replace the one on the iMac.
