You are misinformed.  It will use Safari if that's what the system default is.  
It is not looking for any specific browser on OS X.  It is doing the right 
thing and using the browser that the user has configured on their system.  This 
is actually Safari on the Mac by default.

The command is `browse-url', and it is URL as much as it is BROWSE.  
But you absolutely have a point there - I can see how users may get confused.

Once more: as it is now, Emacs does not rely on browsers at all on the Mac in 
its default configuration.
It uses a system mechanism to handle arbitrary URLs, specifically, mailto: 
URLs.  This does NOT invoke the browser.  It invokes the system's standard mail 
client.  

If the user configures a specific browser for Emacs, then yes, we go through 
the browser, and perhaps that is not the best thing to do in that case.  See my 
earlier e-mail: bind the browser-function variable to its default before 
calling browse-url.
 
Are there any cases where this would cause problems?
