Microsoft OneNote is available for eligible users. Only NoteBooks stored in Microsoft OneDrive are supported.
OneNote on Mac requires that the user has a license for OneDrive in addition, even when he only wants to store the notes locally on his Mac. The extra license is automatically assigned by the supporters when the user requests a OneNote license via https://cern.service-now.com/service-portal?id=sc_cat_item&name=O365-License&se=Productivity-Software. There is no need to install the OneDive app, having the license is fully sufficient
