Good morning: I´m Ricardo Vargas, i´m librarian and i´m in charge to support Students and teachers at Octavio Arizmendi Posada main central library at Universidad de La Sabana, so we use mendeley and today a student ask me about mendeley plugin in Word, she is using Word 2016 and OSX el capitan, but plugin is not working in Word, it doesn´t appear in the reference mennu bar. Thanks so much.
