Mac users have always been running a version or so behind. With the recent release of Office 2016 Preview for Windows the rumors were that a version for Mac was being developed and Office 2016 would finally bring the two platforms in sync.
Today Microsoft has released the Office 2016 Preview for Mac. Office 2016 for Mac includes new versions of Word, Excel, PowerPoint, Outlook and OneNote. While we have not had a chance to test these applications, this like the Windows preview should not be used in a production environment.
