Microsoft has just released a version of OneNote for the Mac. The company is positioning OneNote as a competitor to Evernote, and as such the app does offer some compelling features. One thing that does make OneNote for the Mac particularly notable (pun intended) is that it’s free. The free Mac app also includes 7GB of free storage space on Microsoft’s servers. If you have a new Office 365 account, you unlock more storage as well as access to premium features not available with the free version of OneNote.
