This is a popular one here in DTS, so here goes, hopefully for the benefit 
of all:

First, consider what it is that you really want to know.  Do you want to 
know if you have MultiFinder's temporary memory capabilities around?  Do 
you want to know whether you have _WaitNextEvent as opposed to 
_GetNextEvent?

In other words, please try to check for a specific piece of functionality, 
rather than trying to globally determine whether MultiFinder is around or 
not.  Part of the problem is that there is no supported way to know 
whether MultiFinder is around or not.

Since most of MultiFinder's functionality, from a programmatical 
perspective, exists in the _OSDispatch trap, USUALLY the best thing to do 
is to check to see if _OSDispatch is implemented or not.

Hope this helps!
