Microsoft Releases OneNote as a Free Mac App Store Download
The Mac version is very similar to the Windows version with only a few subtle visual differences. Both versions share the same notebook metaphor, ribbon interface and freeform note-taking features.
Along with a Mac version, Microsoft also is releasing a OneNote clipper browser plug-in for Internet Explorer, Chrome, Firefox and Mac Safari that allows users to save clippings from webpages. This feature is being extended to third-party apps via a new cloud API that provides developers with the ability to integrate OneNote clipping into their apps.
Other new tools in OneNote include Office Lens, which allows users to take a picture of a document and immediately import it into their OneNote QuickNotes with text recognition. Microsoft also enabled a OneNote email service that provides users with the ability to create new QuickNotes using a unique onenote.com email account.
Microsoft OneNote for the Mac [Direct Link] is available for free from the Mac App Store. While the consumer version is free, Microsoft is still offering a paid business version with premium features like Outlook integration and SharePoint support. New partner apps with support for OneNote include Feedly, IFTTT, News360 and Weave.
