Question details

The user is experiencing OneDrive sync failures and Microsoft Word save permission errors on a Mac after replacing the motherboard and restoring the system from a Time Machine backup.

Product: Microsoft Word, OneDrive
Device & OS: macOS
Scenario: Saving Word files and syncing OneDrive following a Mac hardware replacement and subsequent Time Machine system restore.
Observed behavior: OneDrive completely stops syncing and repeatedly requests access. Microsoft Word cannot save files due to a permission error, despite folder permissions displaying as 'Read & Write'. Microsoft Excel remains unaffected.

Before you start

Before troubleshooting, verify that your Mac is running the latest version of macOS and ensure that both Microsoft Word and OneDrive are fully updated.

Solution 1Recommended

Test OneDrive and Word in a New macOS User Account

Creating a new local Mac account helps determine if the permission error is isolated to your current user profile or is a system-wide issue.

Time Machine restores can sometimes cause permission inconsistencies linked to a specific macOS user profile. Creating a fresh profile isolates the issue.

Open Mac System Settings

Click the Apple menu in the top-left corner of your screen and select 'System Settings' (or 'System Preferences' on older macOS versions).

Add a New User

Navigate to 'Users & Groups', click 'Add Account', and enter your current administrator password when prompted to create a new Standard or Administrator account.

Log into the New Account

Log out of your current session via the Apple menu, log into the newly created account, and launch OneDrive and Microsoft Word.

Test the Issue

Attempt to set up OneDrive sync and save a Word document to see if the permission error persists in this fresh environment.

Testing Results: If Word saves properly in the new account, the issue lies within your original user profile's hidden library permissions.

Solution 2

Contact Apple Support for Deep Permission Repair

If the issue persists even in a new account, the Time Machine restore may have caused deeper system-level file permission errors requiring Apple's assistance.

Frequently Asked Questions

Why does OneDrive keep asking for access after a Mac motherboard replacement?

Replacing a motherboard changes the Mac's hardware identifier. When restoring from a Time Machine backup, this can create mismatches in system hardware IDs and user profile permissions, causing macOS sandboxing to constantly re-prompt for application access.

Why can Excel save files but Word shows a permission error?

Microsoft Word and Excel handle temporary file creation and macOS sandboxing differently. An underlying hidden folder permission issue might block Word's specific temporary save mechanisms while leaving Excel unaffected.

Can I manually fix macOS folder permissions for Word?

While you can check the 'Get Info' panel to ensure your target folder is set to 'Read & Write', deeper macOS sandbox container permissions might still be broken. Creating a new Mac user profile is the most effective way to verify and bypass this.
