If you are a Sierra OS user, you must use EndNote 8x. None of the earlier versions of EndNote are compatible.
2) Quit your word processing program AND the whole connected suite. In other words, quit Outlook, Excel, etc. Closing the window (clicking the red button) is not enough. Make sure you File>Quit.
3) Download the Firefox web browser. Chrome and Safari have trouble exporting database results to your EndNote program.
The first time you send database references to EndNote, you must designate the program to open files in Firefox . Follow the directions in the video.
