How to Fix Word for Mac Permission Errors with EndNote or Zotero
Question details
Users encounter permission denied errors when trying to use reference managers like EndNote, Zotero, or Mendeley with Microsoft Word for Mac.

- Product
- Microsoft Word for Mac, EndNote, Zotero, Mendeley
- Device & OS
- macOS Catalina or later
- Scenario
- Attempting to insert citations or interact with reference manager add-ins within Word for Mac.
- Observed behavior
- Word for Mac displays an error stating it lacks permission to interact with the citation plugin due to macOS sandbox and privacy restrictions.
Ensure that you have administrator privileges on your Mac, as you will need them to modify system privacy settings. Save your current document and close Microsoft Word before making changes.
Grant macOS Privacy and Security Permissions
Modify your Mac's system settings to allow Word and your reference manager to communicate with each other.
Apple's application sandbox on macOS Catalina and newer requires explicit user permission for apps to interact. If this permission is denied, plugins like EndNote and Zotero cannot communicate with Microsoft Word.
Click the Apple menu in the top-left corner of your screen and select 'System Settings' (or 'System Preferences' on older macOS versions).
Scroll down and click on 'Privacy & Security' in the left sidebar, then find and click on 'Automation' in the main panel.
Look for 'Microsoft Word' and your reference manager (e.g., EndNote or Zotero) in the list. Check the boxes underneath them to allow mutual control and communication.
Close the settings window. Completely quit both Microsoft Word and your reference manager, then reopen them to apply the new permissions.

Update Microsoft Word and Your Citation Manager
Ensure both applications are up to date, as newer versions often contain fixes for macOS compatibility and sandbox issues.
Try WPS Office for Seamless Document Editing
If you continue facing sandbox permission errors and plugin issues in Microsoft Word for Mac, consider switching to WPS Office. It is a highly compatible, free, and lightweight suite that handles standard document formats smoothly.
- 1. Download WPS Office: Visit the official WPS website and download the macOS version of WPS Office.
- 2. Install the Software: Open the downloaded file and drag the WPS Office icon to your Applications folder.
- 3. Open Your Documents: Launch WPS Office and easily open all your existing .docx files to continue editing without permission errors.

Frequently Asked Questions
Why does Word for Mac suddenly block EndNote or Zotero?
This usually happens after a macOS update. Apple's updated sandbox security restricts apps from interacting without explicit user consent, causing communication errors between Word and third-party plugins.
What should I do if Microsoft Word is missing from the Mac Automation privacy list?
If the apps do not appear in System Settings > Privacy & Security > Automation, try reinstalling the citation manager plugin. If it still fails, the add-in developer may need to update their software to trigger the Apple sandbox permission prompt properly.
Are there similar sandbox permission errors in other Office apps?
Yes, Excel and PowerPoint for Mac can also experience sandbox permission issues when interacting with third-party tools, add-ins, or external files. Granting Full Disk Access or Automation permissions often resolves them.
