One Drive fail in MacBook

Follow these steps on the MacBook to restore OneDrive sync:

1. Confirm OneDrive is running
   • Look at the right side of the macOS menu bar for the OneDrive cloud icon.
   • If it is missing, use Spotlight search to look for “OneDrive” and open it.
2. Restart OneDrive
   • Select the OneDrive cloud icon in the menu bar.
   • Choose Quit OneDrive.
   • Use Spotlight again to search for OneDrive and reopen it, then check if sync resumes.
3. Check access to OneDrive online
   • Select the OneDrive cloud icon in the menu bar.
   • Click the three dots (…) and choose View online.
   • If sign-in to OneDrive on the web fails, resolve the online sign-in issue first before retrying sync.
4. Update OneDrive to the latest version
   • If OneDrive is not installed or is failing to start, download the latest sync app for Mac from the official download page or the Mac App Store, as documented.
   • Open OneDrive, sign in with the account used on the MacBook, and complete setup.
5. Unlink and re-link the Mac to OneDrive
   • Click the OneDrive cloud icon in the menu bar.
   • Select Help & Settings → Preferences.
   • Go to the Account tab and select Unlink this Mac.
   • Use Spotlight to open OneDrive again.
   • Sign in; when prompted that a OneDrive folder already exists, choose Use this folder (or Choose new folder if a different location is desired).
   • Allow time for OneDrive to re-sync files.
6. Clear cached credentials (if sign-in or account errors occur)
   • Open Keychain Access via Spotlight or from Applications → Utilities.
   • Search for “OneDrive”.
   • Delete OneDrive Cached Credential (or delete the OneDrive-related keychain as described in the documentation).
   • Start OneDrive again and sign in.
7. If sync is still stuck (for example, on “Processing changes”) or specific folders do not sync
   • Temporarily pause and resume sync:
     • Select the OneDrive icon → Pause syncing → choose a time.
     • Move one file out of a OneDrive sync folder to a non‑OneDrive folder.
     • Select the OneDrive icon again → Resume syncing.
     • After sync completes, move the file back.
   • Ensure the Mac has the standalone OneDrive sync app (not only the Mac App Store version) if using Desktop & Documents backup, and grant OneDrive Full Disk Access in System Preferences → Security & Privacy → Privacy.

If these steps do not restore sync, reset or reinstalling OneDrive using the official reset/uninstall guidance in the referenced articles is the next step; this does not delete files from OneDrive, only the local sync configuration.
