Microsoft Office 2016 Beta for Mac for free
Microsoft offers downloads of its Microsoft Office 2016 Preview for Mac for free. That's the first beta offer we've seen for this software, which is only available for free until the full version goes live. (It's due to be released in the second half of this year.) It features Word, Excel, PowerPoint, OneNote, and Outlook, all optimized for Mac.
