A few days ago, Microsoft released the Office 2016 suite for Mac.
Next to the improved display for devices with a Retina display, one of the main features is the improved support for OneDrive, OneDrive for Business and Sharepoint. A complete list of improvements can be found on the Office for Mac website.
If you are a current Office 365 user with a license that includes the Office Suite and your tenant administrator allowed it, you can download the software from your personal Office 365 portal now!
