EndNote X7 is not currently compatible with Microsoft Word 2016 for Mac. The vendor, Thomson Reuters, will be releasing a free patch for it in September or October. In the meantime, Office 2011 is available for free to McGill students, faculty, and staff through the Office 365 site. If you've already installed Office 2016, however, workarounds are available.
The new version of EndNote software - version X7 (Windows) - is now available for download at http://kb.mcgill.ca/it/endnote. We will no longer be offering ProCite or Reference Manager since the software provider is no longer updating them, and the McGill community has access to both Endnote and RefWorks.
