title: Unable to unpickle a file on Mac that was pickled on Windows
body: <p>I've got a simple class that I am pickling(dumping) to a file. On OS X this works fine, and on Windows this works fine.</p>
  
  <p>However, while on windows I can load/unpickle the object fine - when windows then pickles this file and saves it back to disk, it becomes unreadable on OS X (although in Windows it still behaves as normal).</p>
  
  <p>The error I get back from OS X is that it is unable to import the require class.</p>
  
  <p>I'm confused as this all works fine as long as I don't pickle anything in windows! (Even then it still works fine in Windows)</p>
  
  <p>I've heard it could be line endings, my other thoughts are possibly something to do with the encoding type used being different across operating systems? But I really have no idea what to try to fully diagnose and/or solve this problem, so any help would be appreciated!</p>
