Correct, this would only be if the user has explicitly changed the 
default fixed width font.

`NSFont` has a method to return the default fixed width font, from 
Python you can use this code to obtain it:

     #!/usr/bin/python
     import objc
     from AppKit import NSFont

     font = NSFont.userFixedPitchFontOfSize_(0)
     print("family: %s, name: %s, size: %.1f" % (font.familyName(), 
font.fontName(), font.pointSize()))

On my system it prints:

     family: Menlo, name: Menlo-Regular, size: 11.0

I deliberetly hardcoded the shebang to call `/usr/bin/python` as PyObjC 
(the Cocoa bridge used here) may not be installed for a custom python on 
the user’s system.
