Question details

The user encounters an error when trying to open Microsoft Word files that were migrated to a new Mac using a Time Machine backup.

How to Fix Word Errors When Opening Files on a New Mac

Product: Microsoft Word
Device & OS: macOS
Scenario: Opening Word documents after migrating data to a new Mac computer via Time Machine.
Observed behavior: Word displays an error message and refuses to open the transferred files, which may be caused by macOS sandbox permissions, directory location issues, or corrupted data during migration.

Before you start

Verify if the affected Word documents can still be opened successfully on your original Mac or on another device to ensure the files themselves are not permanently corrupted.

Solution 1Recommended

Grant Word Access Permissions and Move Files

Moving files to a standard user folder and ensuring Word has system permission can resolve access denial errors on macOS.

When transferring files to a new Mac via Time Machine, strict macOS sandbox permissions might block Microsoft Word from accessing files depending on their restored location.

Move to Documents Folder

Locate a problematic Word file on your new Mac and drag it into the default macOS 'Documents' folder.

Check App Permissions

Open the Apple menu, go to System Settings > Privacy & Security > Files and Folders. Expand 'Microsoft Word' and ensure it has access to your Documents folder.

Test the File

Double-click the moved file inside the Documents folder to verify if Word can now open it without the error message.

Grant Word Access Permissions and Move Files

Permission Granted: If the file opens successfully, you can move your other migrated documents to standard macOS user folders like Documents or Desktop to ensure Word has access to them.

Solution 2

Restore Files Again via Time Machine

If the initial Time Machine migration was incomplete, restoring the specific files again can fix data corruption.

Free Microsoft Office alternative

Frequently Asked Questions

Why do files transferred via Time Machine show as corrupted in Word?

This usually happens if the backup process was interrupted, resulting in incomplete file data. It can also occur if macOS assigns incorrect ownership permissions to the files on the new Mac, causing Word to misinterpret the system access denial as file corruption.

How can I check if a Word document is actually corrupted or just has a permission issue?

Try moving the file to your Mac's Desktop or Documents folder. If it opens there, it was a permission or directory location issue. Alternatively, transfer the file to another device or upload it to a cloud service (like Google Drive or WPS Cloud) to see if it successfully opens elsewhere.

Does macOS handle Word document permissions differently on newer Macs?

Yes, modern macOS versions use strict application sandboxing. Applications like Microsoft Word must explicitly be granted permission to access standard folders (like Desktop, Documents, or Downloads) and external drives. These permissions are managed under System Settings > Privacy & Security.
