I have same problem says that "You can’t open the application “Zotero.app” because it is not responding." How to solve it, I have to submitt master thesis in a week.
Restart your computer, check for any Zotero updates (Help → Check for Updates), reinstall the Word plugin from the Cite → Word Processors pane of the Zotero preferences, and try again.
