How to Stop SharePoint from Syncing with OneDrive on Mac

Click the OneDrive cloud icon in the top Menu bar, select the gear icon (Help & Settings), and click 'Quit OneDrive'.

Open Finder, go to the Applications folder, right-click on the OneDrive app, and select 'Show Package Contents'.

Navigate to Contents > Resources. Find and double-click the file named 'ResetOneDriveApp.command' (or 'ResetOneDriveAppStandalone.command' depending on your version).

Launch OneDrive from the Applications folder, sign in with your Business credentials, and check your Account settings to manage or stop SharePoint syncing.

Open your locally synced OneDrive or SharePoint folder in Finder and look for deeply nested folders or files with exceptionally long names.

Rename the identified files to be shorter, or move them to a folder closer to the root directory to reduce the overall path length.

Allow OneDrive a few moments to process the changes. Once the path limits are resolved, check if the application stabilizes and allows you to manage SharePoint sync options.

Take note of the exact SharePoint libraries syncing unexpectedly, the missing controls in your settings, and your macOS version.

Contact your organization's Microsoft 365 administrator or IT support desk and provide them with your documentation.

If the administrator cannot resolve the issue via the Microsoft 365 Admin Center, request that they open an official support ticket so Microsoft can review your OneDrive logs.
