How to Fix OneDrive for Mac Setup Required After Every Restart
Question details
Users experience a recurring issue where OneDrive fails to remember its configuration, requiring a full setup process upon every system reboot.

- Product
- OneDrive
- Device & OS
- macOS
- Scenario
- Restarting the Mac and attempting to use OneDrive for background file synchronization.
- Observed behavior
- The OneDrive application fails to retain its configuration, repeatedly requesting sign-in, folder selection, and account setup after each system restart.
Ensure your macOS is fully updated and check whether you originally downloaded OneDrive directly from the Microsoft website (standalone version) or the Mac App Store, as the cache clearing steps may vary slightly.
Unlink Account and Clean Reinstall OneDrive
Unlinking your Mac and performing a clean reinstallation often resolves persistent configuration loops caused by corrupted local cache data.
This method involves removing the current configuration and cached application files to force OneDrive to create a fresh, stable settings profile on your Mac.
Click the OneDrive cloud icon in your menu bar, select the gear icon for Settings, navigate to the Account tab, and click 'Unlink this Mac'.
Quit the OneDrive application completely. Then, open your Applications folder and drag the OneDrive app to the Trash.
In Finder, press Cmd+Shift+G and enter '~/Library/Group Containers/'. Locate and delete any folders associated with 'UBF8T346G9.OneDrive' or 'UBF8T346G9.OfficeOneDriveSyncIntegration'.
Download the latest standalone version of OneDrive from the official Microsoft website or the Mac App Store, install it, and complete the sign-in and folder selection setup.

Frequently Asked Questions
Why does OneDrive keep asking me to sign in on my Mac?
This usually occurs due to corrupted macOS Keychain entries or incorrect permissions in the OneDrive cache folders, preventing the application from securely saving your login credentials across reboots.
Is there a difference between the Mac App Store version and the standalone version of OneDrive?
Yes. The Mac App Store version runs in a sandboxed environment which can sometimes lead to strict permission restrictions. The standalone version downloaded directly from Microsoft has broader system access, which can sometimes resolve persistent sync bugs.
Will unlinking my OneDrive account delete my local files?
No, unlinking your account only disconnects the synchronization process between your Mac and the cloud. Your locally downloaded files will remain untouched on your hard drive.
