When I received my Macbook, I realized, my family's Windows operating computers could not translate documents sent from Mac's word documenting system (This system is called Pages).  I spent weeks trying to find a way to make the documents translatable for Windows.  Then I found the key.

When you are ready to send your Pages document, go up to the top bar, hold your cursor on "File" then a bar should drop down.  Then hold your cursor over "Export To" and then you can click Microsoft Word, PDF and many more options.  Now your document is ready to send to a "Non-Mac" computer!
