EndNote X6 and prior were developed prior to Office and Word 2016 for the Mac, and they are not currently compatible. We apologize for any inconvenience this may cause.  EndNote X6 for Mac was designed to work with Word 2008 and 2011, and one of these versions of Word would be needed to use EndNote with Word.

I apologizefor any inconvenience this may have caused.

EndNote X7 will work with Word 2016. Since you own a previous version of EndNote, you would be eligible for an upgrade version of EndNote X7. You can place your order through our purchase page (http://www.endnote.com/enpurchase.asp) or you may also contact our sales team for more information on upgrades and current offers.
