You'll have to provide more information on what it is you're fuzzing. Unless
you're fuzzing part of the OS or system libraries, there shouldn't be much
difference between running on Linux or running on OS X. I fuzz all my stuff
under Linux because I've got access to servers to run it on, but then debug
the issues that are found under Windows because I prefer the debugger there.
