Microsoft's OneNote app has been available on mobile, Windows and the web for quite some time, but Mac support for the note-taking software has proven elusive... at least, until now. Both The Verge and ZDNet hear that OneNote will be available for free on OS X later this month. Microsoft would also release a free desktop Windows app (the Windows 8-native app is already gratis) to better support its own platform. Both versions would include new features, too, including a Clipper service to save web content and a desktop variant of Office Lens' document scanning. We've reached out to Microsoft to verify the claims. It's easy to see why the folks in Redmond might expand OneNote's ecosystem, though. The app is facing stiff competition from Evernote, which is available on most modern platforms -- Microsoft would simply be countering a rival.
