OneDrive for macOS has a new housekeeping feature called "Clean Up to Boot Performance which detects a synced document library (typically a SharePoint or Teams library) that has not been accessed for over a year. OneDrive now prompts you to remove the local synchronization to improve performance.
What "Clean Up and Remove" does
Selecting Clean Up and Remove:
- Stops syncing that SharePoint library to your Mac.
- Removes the local File Provider representation of that library from Finder.
- Does not delete any files from SharePoint or OneDrive.
- Does not affect other users.
- Frees Finder and OneDrive from tracking an unused sync relationship, which can reduce background activity and improve performance.
If you later need the library again, you can simply navigate to the SharePoint site and choose Sync again.
What it does not do
It does not:
- Delete cloud data.
- Delete the SharePoint library.
- Remove your permissions.
- Affect any other synced libraries.
- Delete your personal OneDrive files
Should you click it?
If you haven't used that SharePoint library in over a year, there is essentially no downside. You can always re-sync it later. If the library is still part of an active workflow—even if only occasionally—select No Thanks and keep it synced.
