title: Obtaining previous versions of Mac OS X for testing
body: <p>I'm porting some code to OSX and am in need of some copies of older OSX versions.  Does the Mac Developer program allow downloading of previous OSX versions?  A few forums mention it, but I've found conflicting/old info on this.  It doesn't appear to be here:</p>

  <p>I'm also aware of this post <a href="https://stackoverflow.com/questions/3629523/does-the-mac-developer-program-have-old-versions-of-mac-os-x">Does the Mac Developer Program have old versions of Mac OS X?</a>, but this is now 3 years old. I'm aware some versions can be purchased on Amazon--would rather not go that route though unless necessary.  What is the common way to test OSX applications for backwards compatibility?  </p>
  
  <p>Thanks!</p>
