Solution 1Recommended

Disable or Uninstall the Mendeley Add-in

Since the crash is directly related to the Mendeley add-in, removing or disabling it is the most effective way to restore Word's functionality.

Often, third-party add-ins like Mendeley become incompatible after a macOS or Microsoft Office update, leading to application hangs and SIG_HANG_QUIT errors.

1
Open Add-ins Manager

Launch Microsoft Word. If it crashes immediately, try launching it while holding the Shift key to bypass startup items. Go to the 'Insert' tab and click on 'My Add-ins' or 'Get Add-ins'.

2
Remove Mendeley

Locate the Mendeley Cite add-in in the list. Click the three-dot menu icon next to it and select 'Remove' to uninstall the add-in from Word.

3
Restart Microsoft Word

Close Microsoft Word completely and reopen it normally to verify if the crashing issue has been resolved. If Word runs smoothly, contact Mendeley support for an updated, compatible version.

Citation Data is Safe: Uninstalling the add-in will not delete your reference library. Your citations remain safely stored in your Mendeley account.

Frequently Asked Questions

What does the SIG_HANG_QUIT error mean in Word for Mac?

This diagnostic error indicates that the Word application has stopped responding to the macOS operating system, often due to a conflicting third-party add-in like Mendeley looping or freezing the software.

Will I lose my Mendeley citations if I disable the add-in in Word?

No, disabling or uninstalling the add-in only stops the integration with Microsoft Word. Your citation library remains safely stored in your Mendeley desktop app and your online Mendeley account.

How do I update the Mendeley add-in for Word on Mac?

You can update the add-in by opening the Mendeley Reference Manager, navigating to the Tools menu, and selecting the option to install or update Mendeley Cite for Microsoft Word. Alternatively, check for updates within the 'Get Add-ins' store in Word.

Why is the diagnostic crash report not enough to fix the issue?

The diagnostic crash report (like the SIG_HANG_QUIT log) is primarily useful to software engineers to track down exact memory faults. For users, practical troubleshooting steps like safe mode, disabling add-ins, and updating the software are the actual ways to fix the problem.
