Essentially there is a nice easy list of paths on modern OSX systems here:
What is happening is that unfortunately the $PATH that Livecode sees is not
the same as your users shell - due to varied ways that users systems are
You want to use the above script on startup to automatically configure your
$PATH in Livecode for things like "brew" and npm.
