Fix Microsoft Word and Excel Closing Unexpectedly on Mac
Question details
The user is experiencing unexpected closures or crashes of Microsoft Word and Excel on a macOS device, needing to find out why the apps fail and how to diagnose the issue.
- Product
- Microsoft Word, Microsoft Excel
- Device & OS
- macOS
- Scenario
- Working on documents or spreadsheets on a Mac, potentially while using virtual classroom software.
- Observed behavior
- Microsoft Word and Excel applications keep quitting unexpectedly, or document windows close abruptly without any error warning.
Before proceeding with troubleshooting, save your work in any other open applications and note down any specific actions that trigger the crash.
Diagnose Office Versions and Software Conflicts
Gathering exact version details and isolating third-party software (like virtual classroom apps) is the most critical step to identifying why Office is crashing.
Unexpected application closures often result from compatibility bugs between specific macOS versions, Office builds, or interfering background software.
Open Microsoft Word. Click on 'Word' in the top-left Mac menu bar and select 'About Microsoft Word'. Note the exact version number and your Office license type.
Click the Apple logo in the top-left corner of your screen and select 'About This Mac'. Record the macOS version installed on your device.
Determine if the entire application crashes (the indicator dot under the app icon in the Dock disappears) or if only the document window closes while the top menu bar remains active.
If you are running virtual classroom or screen-sharing software, close these applications completely from the Activity Monitor. Relaunch Word or Excel to see if stability improves.
Update macOS and Microsoft Office
Running outdated software can lead to random crashes. Updating ensures you have the latest stability patches.
Boot Mac in Safe Mode to Test
Safe Mode clears system caches and disables third-party startup items, which helps verify if a background app is causing Word and Excel to close.
Switch to WPS Office for a Stable Mac Experience
If Microsoft Office continues to crash and disrupt your workflow on macOS, consider switching to WPS Office. It provides a lightweight, highly stable, and fully compatible alternative for all your document needs without the heavy resource usage.
- 1. Download for Mac: Visit the official WPS Office website and download the macOS installation package.
- 2. Install the Application: Open the downloaded .dmg file and drag the WPS Office icon into your Applications folder.
- 3. Open Your Files Safely: Launch WPS Office and directly open your existing Word or Excel files to continue working without unexpected crashes.
Frequently Asked Questions
Why does Microsoft Word crash when I use virtual classroom software?
Virtual classroom and video conferencing tools often consume high CPU and RAM resources, and they may hook into screen rendering processes. This can create conflicts with Office applications, causing them to freeze or quit unexpectedly.
How do I recover a Word document if the app closed unexpectedly on my Mac?
Reopen Microsoft Word immediately; the Document Recovery pane should appear automatically. Alternatively, you can search for AutoRecover files by opening Finder, holding the 'Option' key, clicking 'Go' in the menu bar, selecting 'Library', and navigating to Containers > Microsoft Word > Data > Library > Preferences > AutoRecovery.
Can a corrupted specific document cause Word or Excel to close?
Yes. If only one specific file causes the application to crash while others work fine, the file itself is likely corrupted. Try opening the file in a different application, like Pages, Numbers, or WPS Office, and resaving it to clear the corruption.
Will reinstalling Microsoft Office on my Mac stop the unexpected closures?
If the issue stems from corrupted installation files, reinstalling can help. Before reinstalling, you should completely uninstall Office by dragging the apps from the Applications folder to the Trash, and clearing the associated Library files.
