Fix Microsoft Word Not Opening on Mac

If Microsoft Word refuses to open on your Mac—whether it bounces in the Dock and disappears, shows a blank window, or crashes on launch—the top fix is to reset Word’s preferences. This resolves the majority of launch failures because corrupted preference files are the most common culprit, and the process takes under two minutes.

What to Look For

When choosing a fix, consider these criteria:

• Ease of execution – How many steps and how technical are they? Some fixes are one-click, others require Terminal.
• Time to complete – A preference reset takes seconds; a full reinstall takes 20+ minutes.
• Data safety – Does the fix risk your documents, templates, or custom settings? Most don’t, but a few do.
• Success rate – Which fixes address the most common causes (corrupt prefs, licensing, permissions, outdated versions)?
• Reversibility – Can you undo the fix if it doesn’t help? Some are reversible, others are not.

1. Reset Word Preferences

What to do: Quit Word, open Finder, press Cmd+Shift+G, type ~/Library/Group Containers/UBF8T346G9.Office/User Content/ and hit Go. Find the Preferences folder inside, and move the file named com.microsoft.Word.plist to your Desktop. Also look for a Word folder in the same location and move it to the Desktop as well. Relaunch Word—it will create fresh preference files.

Strengths: This is the single most effective fix for Word not opening, especially if it crashes immediately after launch. It preserves your documents and most custom settings (though some preferences like recent files may reset).

Trade-offs: You’ll lose custom toolbar layouts, keyboard shortcuts, and some autocorrect entries. If the problem isn’t preference-related, this won’t help.

Best for: Users whose Word crashes on launch, shows a blank window, or freezes during startup.

2. Check for Updates

What to do: Open any other Office app (like Excel) or go to the Mac App Store (if you installed Word from there). For the standalone version, open Word’s menu bar (if it opens at all) and go to Help > Check for Updates. If Word won’t open, download the latest update from Microsoft’s website manually.

Strengths: Updates fix known bugs that cause launch failures, especially after a macOS update. It’s a one-click solution and requires no technical knowledge.

Trade-offs: Requires an internet connection and may take a few minutes to download. If your macOS version is too old, the latest update may not install.

Best for: Users who recently upgraded macOS or haven’t updated Office in a while.

3. Sign Out and Back Into Office

What to do: If Word opens but shows a sign-in screen or a licensing error, go to Word > Sign Out (if you can get that far). If not, open Keychain Access (in Utilities), search for Microsoft Office, and delete all related entries. Then relaunch Word and sign in again with your Microsoft account.

Strengths: Fixes issues where Word opens to a blank window or shows “Product Activation Failed.” It also resolves sync problems with OneDrive.

Trade-offs: You’ll need to re-enter your password and possibly re-activate Office. Deleting Keychain entries can affect other Office apps (they’ll also require re-sign-in).

Best for: Users who see licensing errors, or who have multiple Microsoft accounts on the same Mac.

4. Repair Disk Permissions (via First Aid)

What to do: Open Disk Utility (in Applications/Utilities), select your startup disk (usually “Macintosh HD”), click First Aid, and run it. This repairs file permissions and disk errors that can prevent Word from launching.

Strengths: It’s a system-level fix that can resolve underlying issues affecting all apps, not just Word. It’s safe and doesn’t touch your documents.

Trade-offs: Takes several minutes and may require a restart. It’s less likely to fix the problem if the issue is specific to Word’s own files.

Best for: Users who also experience other app crashes or system sluggishness, suggesting a deeper disk problem.

5. Reinstall Microsoft Word

What to do: First, quit Word. Open Finder, go to Applications, and drag Microsoft Word to the Trash. Then reinstall from the Mac App Store or from your Microsoft account (if you have a standalone license). If you have the full Office suite, you can reinstall just Word via the Microsoft 365 installer (it allows custom install).

Strengths: A clean install replaces all corrupted app files, which is the most thorough fix. It also ensures you have the latest version.

Trade-offs: Time-consuming and requires your product key or Microsoft account login. You may lose some custom dictionaries and templates unless you back them up.

Best for: Users whose Word still won’t open after trying all other fixes, or who have a severely corrupted installation.

6. Use Terminal to Clear the Office Cache

What to do: Open Terminal (in Utilities) and run this command: rm -rf ~/Library/Containers/com.microsoft.Word/Data/Library/Caches. Then relaunch Word. This clears the app’s cache files that can become corrupted.

Strengths: It’s a targeted fix that doesn’t affect your documents or preferences. It’s fast and effective if the issue is a corrupt cache.

Trade-offs: Requires comfort with Terminal commands. If you mistype, you could delete the wrong folder (though the command above is safe if copied exactly).

Best for: Users who are comfortable with command line and want a quick fix without resetting preferences.

How to Choose

Start with the least invasive and most likely fix: reset preferences. It’s free, fast, and fixes the majority of Word launch issues. If that doesn’t work, check for updates—especially if you’ve recently updated macOS. If you see a licensing error, sign out and back in. For persistent crashes, run Disk Utility’s First Aid. Only as a last resort should you reinstall Word, as it’s the most time-consuming and may require re-activation.

Budget-wise, all these fixes are free (except the cost of your Office subscription). If you’re on a time crunch, the preference reset and cache clear are the quickest. If you’re not technical, stick to the GUI-based methods (preferences, updates, sign-in, reinstall) and avoid Terminal.

Frequently Asked Questions

Will resetting Word preferences delete my documents?

No. Your documents are stored in your Documents folder or OneDrive, not in the preferences folder. Only settings like toolbar layouts and recent files are reset.

Why does Word open but show a blank white window?

This is often caused by a corrupted preference file or a display issue. Try resetting preferences first. If that fails, check for updates—older versions sometimes have graphics bugs with newer macOS versions.

I get “Microsoft Word has expired” even though I have a subscription. What should I do?

Sign out of Office in Word (if possible), then sign back in. If that doesn’t work, check your subscription status at account.microsoft.com. Sometimes the issue is a time/date mismatch on your Mac—make sure “Set time and date automatically” is enabled in System Settings.

Can I reinstall Word without losing my custom templates?

Yes, if you back up your templates first. They’re usually in ~/Library/Group Containers/UBF8T346G9.Office/User Content/Templates. Copy that folder to a safe location before reinstalling, then restore it afterward.

Why does Word crash immediately after I click the icon?

This is typically a corrupted preference file or an incompatible add-in. Reset preferences first. If you have third-party add-ins installed, remove them from ~/Library/Group Containers/UBF8T346G9.Office/User Content/Add-ins and try again.

Is it safe to delete the com.microsoft.Word.plist file?

Yes. Word will create a new one when it launches. It only stores settings like your default font and recent documents, not your actual documents.

Bottom Line

For most users, the preference reset is the best first step—it’s quick, safe, and fixes the most common cause. If that doesn’t work, work through the list in order: updates, sign-in, disk repair, cache clear, and finally reinstall. In nearly all cases, one of these six methods will get Word running again without any data loss.
