Fix Microsoft Word for Mac Crashing When Multiple Files Are Open
Question details
Microsoft Word for Mac unexpectedly crashes and throws memory-access errors when the user attempts to work with multiple documents simultaneously.

- Product
- Microsoft Word for Mac
- Device & OS
- MacBook Pro (macOS)
- Scenario
- Opening and editing multiple document files at the same time in the Word application.
- Observed behavior
- The application crashes entirely, displaying EXC_BAD_ACCESS and KERN_INVALID_ADDRESS errors. A standard software reinstallation fails to resolve the underlying problem.
Make sure to force-close any frozen applications using the Activity Monitor and verify that your Mac has sufficient available RAM to handle multiple large documents.
Reset Word Preferences by Deleting Normal.dotm
Corrupted global templates are a leading cause of memory-access crashes on Mac. Deleting the corrupted template forces Word to generate a clean version upon the next startup.
When Word crashes with EXC_BAD_ACCESS, the application is trying to access restricted memory. Standard reinstallation often leaves user preference files and caches intact, meaning a corrupted configuration will persist even after a fresh installation. Manually deleting the default template file is required to clear these corrupt settings.
Ensure Microsoft Word, Excel, and PowerPoint are completely closed. Right-click their icons in the Dock and select 'Quit'.
Click on the Finder icon, then press Command + Shift + G on your keyboard to open the 'Go to Folder' search box.
Type or paste the following path exactly: ~/Library/Group Containers/UBF8T346G9.Office/User Content/Templates and click 'Go'.
Locate the file named 'Normal.dotm'. Drag this file to your Mac's Trash to remove it.
Open Microsoft Word again. The application will automatically create a new, uncorrupted Normal.dotm file, resolving the memory crash.

Update macOS and Microsoft Word
Applying the latest software patches ensures that memory-management bugs causing the KERN_INVALID_ADDRESS error are patched.

Frequently Asked Questions
What does the EXC_BAD_ACCESS error mean in Word for Mac?
This error occurs when an application attempts to access a protected or invalid block of memory. In Word for Mac, it typically indicates a failure in memory management when handling multiple large files, or it can be triggered by a corrupted application template.
Why does Word still crash after reinstalling it on my Mac?
Reinstalling Microsoft Word often leaves user preference files and system caches intact in the hidden macOS Library folder. If a configuration file like Normal.dotm is corrupted, the freshly installed Word application will continue to load it and crash until the file is manually deleted.
How can I prevent memory errors when opening multiple documents?
To prevent memory overload, keep macOS and Word updated to the latest versions. Additionally, regularly clear out background applications using Activity Monitor, disable unnecessary third-party Word add-ins, and avoid keeping an excessive number of graphic-heavy documents open at the same time.
