Error 404 means "File not found". I dont know your PC neither your files, either there is no such file or Apache does not have sufficient rights to read it (Apache runs as a User from your OSX and this User may not have sufficient rights, or the file simply does not exist).

Because this is not sufficient, you have to grant sufficient rights to ALL(!) folders above, especially also for the /home folder itself. That is basic OSX knowledge (not Apache or Xampp knowledge).
