In this guide, we will explore the common causes of these crashes and provide detailed, step-by-step solutions to get your Office apps running smoothly again.

Why Do Word, Excel, and PowerPoint Keep Crashing on Mac?

Before diving into the solutions, it's important to understand why these crashes happen. Here are some of the most common reasons:

1. Outdated Office Applications – Running an outdated version of Microsoft Office can lead to bugs, compatibility issues, and performance instability.
2. macOS Compatibility Issues – If your macOS version is not compatible with your Office version, you may experience crashes or unexpected errors.
3. Corrupt Preference Files – Office applications store preference files that can become corrupted, causing instability.
4. Add-ins or Third-Party Software Conflicts – External add-ins or software installed on your Mac may interfere with Office applications.
5. Insufficient System Resources – If your Mac is running low on memory (RAM) or disk space, Office apps may struggle to function properly.
6. Corrupt User Profile – Sometimes, user profiles on macOS become corrupted, leading to persistent app crashes.

Now that we understand the potential causes, let's explore the solutions.

Step-by-Step Fixes for Word, Excel, and PowerPoint Crashes on Mac

🛠️ Fix 1. Update Microsoft Office and macOS

Outdated software is a leading cause of application crashes. Ensuring that both Office and macOS are up to date can resolve many stability issues.

How to Update Microsoft Office on Mac:

Update within program: You can check and update the software within the program directly:

1. Launch Word, Excel, or PowerPoint, or any other Office program.

2. In the menu bar, select Help.

3. To activate Microsoft AutoUpdate, select Check for Updates.

4. Click Update and let the process finish if there are any updates available.

Update in App Store: You can also update the Office program from App Store. Here is how:

1. Open App Store from launchpad and then click Updates.

2. If there is updated version available, click Update button to update the program.

How to Update macOS:

1. In the upper-left corner, select the Apple menu ().
2. Choose System Settings (or System Preferences in older versions).
3. Click General and then Software Update and install any available updates.
4. Restart your Mac after updating.

🛠️ Fix 2. Restart Your Mac and Check for Background Conflicts

A simple restart can resolve temporary system issues. Additionally, closing background apps that consume excessive resources can help.

Steps to Restart and Free Up Resources:

1. Click on the Apple menu () and select Restart.
2. After rebooting, open Activity Monitor (found in Utilities via Applications).
3. Check for any high CPU or memory usage apps. If Office apps are consuming excessive resources, force quit them and relaunch.

🛠️ Fix 3. Reset Microsoft Office Preferences

Corrupt preference files can lead to instability. Resetting these files often resolves crashes.

Steps to Reset Office Preferences:

1. Shut down every Microsoft Office program.

2. Launch Finder, then go to ~/Library/Preferences.

3. Locate and delete the following files (they will regenerate automatically when you reopen the apps):

• com.microsoft.Word.plist
• com.microsoft.Excel.plist
• com.microsoft.Powerpoint.plist

4. Restart your Mac and reopen Office applications to see if the problem is resolved.

🛠️ Fix 4. Disable Add-ins and Open in Safe Mode

Third-party add-ins can cause Office applications to crash. Running the apps in Safe Mode can help identify the issue.

How to Open Office Apps in Safe Mode:

1. Turn off all Office applications.
2. Press and hold the Shift key while opening Word, Excel, or PowerPoint.
3. If the app works fine in Safe Mode, a faulty add-in is likely the cause.
4. How to Disable Add-ins:
5. Open the Office application normally.
6. Click Insert > Add-ins > My Add-ins.

7. Disable all add-ins and restart the application.
8. Enable add-ins one by one to identify the problematic one.

🛠️ Fix 5. Repair or Reinstall Microsoft Office

When Word, Excel, or PowerPoint keeps crashing on your Mac, one of the most effective solutions is to repair or reinstall Microsoft Office. Over time, Office applications can accumulate corrupted files, conflicting settings, or damaged installation components that may lead to instability. Reinstalling Office ensures you have a fresh, clean copy of the software, free from any previous issues. Below, we'll cover the steps in more detail.

Why Reinstalling Office Can Fix Crashes

Reinstalling Microsoft Office removes all corrupted files, resets configurations to their default state, and ensures that the latest version is installed. Some of the most common problems that reinstalling Office can resolve include:

1. Persistent crashes upon startup – If Office apps crash as soon as you open them, a corrupt installation may be the cause.
2. Features not functioning correctly – Missing toolbars, broken formatting, or disabled options can indicate installation issues.
3. Problems after a macOS update – Sometimes, an update to macOS can cause compatibility issues that a fresh install of Office can resolve.
4. Repeated error messages – If you keep seeing errors related to missing files or failed updates, reinstalling may be necessary.

Step-by-Step Guide to Repair or Reinstall Microsoft Office on Mac

5.1. Check for Built-In Repair Options

Unlike Windows, macOS does not have a built-in repair tool for Microsoft Office. However, before uninstalling, you can try resetting the Office apps to their default state:

1. Open any Office app (Word, Excel, or PowerPoint).
2. Click Help in the menu bar.
3. Select Check for Updates and install any available updates.
4. Restart the application and see if the problem persists.

If Office apps continue to crash, proceed with a full uninstallation and reinstallation.

5.2. Uninstall Microsoft Office Completely

To fully remove Microsoft Office from your Mac, follow these steps:

1. Close all Office applications – Make sure Word, Excel, PowerPoint, and Outlook are not running.
2. Open Finder and go to Applications.
3. Locate the Microsoft Office folder and drag it to the Trash.
4. Delete related Office files from your Library folder:
   • Open Finder, click Go in the menu bar, and select Go to Folder.
   • Type ~/Library/Containers/ and press Enter.
   • Look for any folders starting with com.microsoft. (e.g., com.microsoft.Word, com.microsoft.Excel) and delete them.

   • However, we would recommend that you also check the following directories for possible leftovers:

     ~Library/Application Support
     ~Library/Caches
     ~Library/Preferences
     ~Library/LaunchDaemons
     ~Library/PrivilegedHelperTools

5. Empty the Trash to permanently delete these files.
6. Restart your Mac before reinstalling Office.

5.3. Reinstall Microsoft Office on Mac

Now that you've removed the old installation, it's time to download and install the latest version of Microsoft Office.

1. Open Safari (or any browser) and go to the Microsoft Office website.
2. Sign in with your Microsoft account. If you have an Office 365 subscription, use your credentials to access your downloads.
3. Click Install Office and select the appropriate version for your Mac.

4. Once the download is complete, open the .pkg file and follow the on-screen installation instructions.
5. After installation, open an Office app and sign in with your Microsoft account to activate the software.
6. Check if the issue is resolved by opening Word, Excel, and PowerPoint one by one.

5.4. Verify the Installation and Adjust Settings

Once you've reinstalled Office, it's a good idea to tweak a few settings to prevent future crashes:

• Disable Add-ins: Go to Insert > Add-ins > My Add-ins and disable unnecessary extensions.
• Enable AutoSave: This prevents data loss in case of future crashes. Click Word (or Excel, PowerPoint) from the menu bar and select Preferences, then Save option. There you can enable the option for AutoSave or AutoRecover.

• Adjust Performance Settings: If your Mac is older, lowering the animation settings in PowerPoint and disabling unnecessary features in Word can improve stability.

5.5. What If Office Still Crashes After Reinstallation?

If you've reinstalled Office but are still experiencing crashes, consider these additional troubleshooting steps:

• Try a Different User Profile – A corrupted user profile can still cause Office to crash, even after reinstalling. Try creating a new macOS user account and see if Office works there.
• Check for macOS Compatibility – If your Mac is running an older version of macOS, consider updating it.
• Contact Microsoft Support – If none of the solutions work, reach out to Microsoft Support for further assistance.

🛠️ Fix 6. Free Up Disk Space and Optimize Performance

If your Mac is running low on disk space, Office applications may crash due to memory constraints.

How to Check Available Storage:

1. Click the Apple menu () and go to System Settings > General > Storage.
2. If storage is low, delete unnecessary files or transfer them to an external drive.

How to Clear Cache and Temporary Files:

1. Open Finder, click Go in the menu bar, and select Go to Folder.
2. Type ~/Library/Caches/ and press Enter.
3. Delete unnecessary cache files related to Microsoft Office.

🛠️ Fix 7. Create a New User Profile on macOS

A corrupt user profile may cause Office applications to crash. Creating a new profile can determine if this is the issue.

How to Create a New User Profile:

1. Click the Apple menu () and go to System Settings > Users & Groups.
2. Click Add User and create a new account.

3. Log in with the new account and open Office applications.
4. If the crashes don't occur, the issue is likely related to your original user profile.

When to Contact Microsoft Support

If none of the above solutions work, you may need professional assistance. Contact Microsoft Support if:

• Office apps crash immediately upon opening.
• Reinstalling Office does not fix the issue.
• Crashes occur after a macOS update, and no available fixes work.

You can reach Microsoft Support through:

• The Microsoft Office website.
• The Help section in any Office application.
• Microsoft's official support chat or phone line.

Recover Data after Word/Excel/PowerPoint Crashes

If data loss happen after the Word/Excel/PowerPoint is crashed, don't worry, you can first check the autosaved versions first if the feature was enabled. Otherwise, you can still try to recover the missing MS Office files with the professional Mac data recovery software Donemax Data Recovery.

The software can deeply scan your hard drive and then try to find any lost files on Mac. Here are the detailed steps to use the software:
