How to fix Microsoft Word when it won’t open on MacBook

1. Restart your MacBook

A simple restart can clear a temporary process or cache that is stopping Word from launching.

1. Save your work and close other apps.
2. Click the Apple menu.
3. Select Restart.
4. Try opening Word again.

2. Update Microsoft Office

An outdated Office build can cause compatibility problems with macOS. Microsoft recommends keeping Office updated, and recent support guidance also points to updating macOS and Office when Office apps stop working properly.

1. Open another Office app such as Excel.
2. Go to Help.
3. Select Check for Updates.
4. Install any available updates.
5. Restart your MacBook and try Word again.

3. Clear Word’s cache and preferences

Corrupted Word preferences can stop the application from launching. Microsoft support guidance has suggested removing Word’s preference file and clearing its cache for this type of problem.

1. Press Command + Shift + G in Finder.
2. Go to:
   ~/Library/Containers/com.microsoft.Word/Data/Library/Preferences/
3. Remove:
   com.microsoft.Word.plist.
4. Check:
   ~/Library/Caches/com.microsoft.Word/ and clear the cache.
5. Try opening Word again.

4. Try Safe Mode

If Word opens in Safe Mode, a cache, startup item, or other software may be interfering with it. Microsoft community guidance has also recommended Safe Mode when Word refuses to launch on MacBook.

5. Reinstall Microsoft Word

If nothing else works, remove Word and install the latest version again. This has also been suggested in Microsoft community discussions where Word would not launch after an attempted reinstall or update.
