According to
http://word.mvps.org/faqs/formatting...TextAfterNotes, the 'suppress endnotes' option in Mac Word is found via Format>Document>Layout. Note that, for your document, the 'whole document' option suggested there is not appropriate to your situation. Note also that the suppression can only be done after you've changed your endnote setup from 'End of document' to 'End of section'.
