The user needs to recover files that were inadvertently renamed, deleted, or corrupted with incorrect file extensions after synchronizing OneDrive with a new MacBook.

Recover Damaged or Renamed OneDrive Files After Mac Sync

Product: Microsoft OneDrive
Device & OS: Mac / macOS
Scenario: Synchronizing an existing OneDrive account's data with a newly installed MacBook.
Observed behavior: Files became renamed, deleted, or assigned incorrect extensions. Attempting a self-service restore returned a GraphError.

Before you start

Immediately pause or stop any further synchronization on your Mac and back up your current local OneDrive data to an external drive to prevent permanent data loss during the recovery process.

Solution 1Recommended

Restore OneDrive to a Previous Point in Time

Use the built-in OneDrive Restore feature to roll back your entire OneDrive library to a state before the Mac synchronization error occurred.

This built-in recovery feature is highly effective for bulk file corruption, accidental deletions, or widespread sync errors.

Please note that utilizing this method will revert the entire drive, meaning any new files uploaded or modifications made after your chosen restoration date will be lost.

Access OneDrive online

Open your web browser, navigate to the OneDrive website, and sign in with your Microsoft account credentials.

Navigate to the Restore feature

Click the Settings gear icon in the top right corner, then select 'Options', and click on 'Restore your OneDrive' from the left navigation menu.

Select a restoration date

Choose a date from the dropdown menu (e.g., 'Yesterday' or 'Custom date and time') that corresponds to a time before you synced the new MacBook.

Execute the restore

Review the activity chart to pinpoint the problematic sync events, then click 'Restore' to revert your files to the selected state.

Restore OneDrive to a Previous Point in Time

Data Loss Warning: Restoring your OneDrive will remove any changes or new files added after the selected restoration date. Ensure you have backed up recent essential files.

Solution 2

Open a Microsoft Support Ticket (OneDrive for Business)

If you encounter a GraphError or cannot restore files yourself on a Business account, your Microsoft 365 administrator must escalate the issue.

Solution 3

Contact Microsoft Support (Personal Accounts)

Personal users experiencing persistent GraphErrors during restoration should reach out directly to Microsoft's support team for remote assistance.

Frequently Asked Questions

Why did my files get renamed or corrupted during the Mac sync?

This can happen due to incompatible characters in filenames, macOS file system differences (APFS vs. NTFS), or temporary synchronization glitches between the OneDrive client and your newly set up Mac.

What does a GraphError mean when trying to restore OneDrive?

A GraphError usually indicates an API communication failure between the OneDrive client and Microsoft's backend servers. This prevents the automated restore process from completing and often requires Microsoft Support intervention.

Can I get remote support for OneDrive as a personal user?

Yes, personal account holders can contact Microsoft Support via the Contact Us page and request remote assistance, though dedicated remote sessions are often prioritized for Microsoft 365 administrators handling business accounts.
