Word Crashing Repeatedly After macOS Tahoe? Fixes

If Microsoft Word keeps crashing after you updated your Mac to macOS Tahoe, the problem is almost always a compatibility issue between Word and the new operating system, a corrupted preference file, or a damaged Office installation. This guide walks you through the exact steps to diagnose and fix the crashes, from quick resets to a full reinstall.

Why Word Crashes After a macOS Update

macOS Tahoe (the version formerly known as macOS 26) introduced significant under-the-hood changes to how apps handle memory, graphics, and file access. Microsoft Word, which relies on older frameworks for document rendering and autosave, can trip over these changes. The most common crash triggers are:

• Outdated Office version – Microsoft releases compatibility patches after every major macOS release. If your Office is not updated, Word may crash on launch or when opening certain files.
• Corrupted Word preferences – The com.microsoft.Word.plist file can become stale after an OS update, causing crashes during startup or when changing settings.
• Damaged Office cache – The Office cache stores temporary data for fonts, templates, and recent files. A corrupted cache can cause random crashes while typing or saving.
• Conflicting third-party add-ins – Old add-ins or macros that were compatible with a previous macOS version may now crash Word.
• Incomplete update installation – If the macOS update was interrupted or the Office update failed, files may be missing or mismatched.

First Steps: Update Office and macOS

Before trying anything destructive, make sure both Office and macOS are fully updated.

1. Open System Settings → General → Software Update and install any pending macOS updates. Apple often releases point releases that fix bugs introduced in the initial Tahoe release.
2. Open the App Store app, click your name in the bottom-left, and check the Updates tab. If Microsoft Word appears, click Update.
3. Alternatively, open Word, go to Help → Check for Updates. This opens the Microsoft AutoUpdate tool. Click Check for Updates and install all available updates.

If Word still crashes after updating, move to the next steps.

Reset Word’s Preferences

Corrupted preference files are a leading cause of crashes after an OS upgrade. Resetting them forces Word to rebuild its settings from scratch, which often resolves the issue.

1. Quit Word completely (press Cmd+Q).
2. Open Finder and press Cmd+Shift+G to open the “Go to Folder” dialog.
3. Type ~/Library/Preferences/ and press Enter.
4. Look for a file named com.microsoft.Word.plist. Move it to your Desktop (or trash) – do not delete it yet, in case you need to restore it.
5. Also look for a folder named Microsoft inside ~/Library/Preferences/ and move it to the Desktop as well.
6. Restart Word. It will create new preference files. If Word works, you can delete the old files. If not, you can put them back.

Clear the Office Cache

The Office cache stores data that speeds up Word, but it can become corrupted after a macOS update. Clearing it forces Word to rebuild its cache from scratch.

1. Quit Word.
2. Open Finder → Go → Go to Folder (Cmd+Shift+G).
3. Enter ~/Library/Containers/com.microsoft.Word/Data/Library/Caches/ and press Enter.
4. Select all files inside the Caches folder and move them to the Trash.
5. Also go to ~/Library/Containers/com.microsoft.Word/Data/Library/Application Support/Microsoft/Office/ and delete the AutoRecovery and OfficeFileCache folders (if they exist).
6. Restart Word. This may slow down the first launch, but it should stop the crashes.

Remove or Disable Add-ins and Macros

Third-party add-ins and macros are a common crash trigger, especially after an OS update. Disable them temporarily to see if they are the culprit.

1. Open Word. If it crashes immediately, hold the Shift key while launching Word to start it in safe mode, which disables add-ins temporarily.
2. If Word opens, go to Tools → Templates and Add-ins.
3. Uncheck any add-ins listed in the Global Templates and Add-ins section.
4. Click OK and restart Word. If the crashes stop, you have found the problem. Re-enable add-ins one by one to identify the specific one.
5. Also go to Tools → Macros → Macros and delete or comment out any macros that run on startup (like AutoOpen).

Repair or Reinstall Microsoft Office

If none of the above work, the Office installation itself may be damaged. A repair (or full reinstall) often fixes persistent crashes.

1. First, try a repair: Open Finder → Applications, right-click Microsoft Word, and select Get Info. Check if there is a “Repair” button (some versions have it). If not, you will need to reinstall.
2. To reinstall, download the Microsoft Office installer from the official Microsoft website (sign in with your Microsoft account).
3. Before installing, it is recommended to remove the existing Office apps. To do this, open Finder → Applications and drag the entire Microsoft Office folder to the Trash.
4. Also delete the container folders: ~/Library/Containers/com.microsoft.Word and ~/Library/Containers/com.microsoft.Office (this will remove your Word preferences and cache, but also any custom dictionaries or templates stored there – back them up first if needed).
5. Run the installer and follow the prompts. Once installed, open Word and sign in to activate it.

Frequently Asked Questions

Will Word crash if I haven’t updated Office in a while?

Yes, that is the most common cause. Microsoft releases updates specifically to fix compatibility with new macOS versions. If you skip updates, Word may crash on launch or when performing basic actions. Always install the latest Office updates before upgrading macOS, or immediately after.

Can I downgrade macOS back to Sequoia to stop the crashes?

Yes, you can downgrade, but it is a drastic step. You would need to erase your Mac and reinstall macOS Sequoia from a backup or a bootable installer. This is time-consuming and may cause data loss if you do not have a backup. Try the fixes above first – they resolve the issue for most people.

Why does Word crash only when I open a specific document?

That suggests the document itself is corrupted, not Word. Try opening the document in another application (like Pages or Google Docs) to see if it works. If it does, you can copy the content into a new Word document. Alternatively, use Word’s “Open and Repair” feature: in the Open dialog, click once on the file, then click the small arrow next to “Open” and select “Open and Repair”.

Will resetting Word preferences delete my documents?

No, resetting preferences only affects Word’s settings (like toolbar layout, default font, and recent files). Your documents are stored separately and will not be touched. However, it will reset your custom dictionary and any macros you have written – back those up if you need them.

Is there a way to prevent Word from crashing during autosave?

Autosave crashes are often caused by a corrupted AutoRecovery file. Go to ~/Library/Containers/com.microsoft.Word/Data/Library/Application Support/Microsoft/Office/ and delete the AutoRecovery folder. Also, try disabling AutoSave temporarily (in Word, go to File → Options → Save and uncheck “AutoSave OneDrive and SharePoint Online files by default”). If that stops the crashes, re-enable it after a few days – the corrupted file is gone.

What if Word crashes immediately after I open it and I cannot access any menus?

Hold the Shift key while double-clicking Word to start it in safe mode, which temporarily disables add-ins and resets some settings. If that works, you can then go to Tools → Templates and Add-ins and remove the offending add-in. If safe mode does not work, you will need to reinstall Office as described above.
