Hello, are you seeing any specific sync error message in OneNote on your Mac?
Open OneNote, select your notebook, then go to File, Sync This Notebook, and check Sync Status for errors. Sign out of your account in OneNote, then sign back in to refresh the connection. Open OneDrive in a browser and confirm the notebook opens there. If it does not sync, close OneNote, reopen it, then update OneNote from Help, Check for Updates. These steps refresh the app connection and force a full sync with your cloud notebook.
