Yep Microsoft office is free for mac during the preview period. The official release for “Microsoft office will be the second half of 2015” says Microsoft. But during the preview period Microsoft office will be free to any Mac user running Yosemite. Microsoft has said “We will update the preview regularly, and you will receive the update via a notification from our Office for Mac Auto-Update tool.” So basically that says that there will be updates regularly. So there still may be some bugs and some problems so don’t expect a full working Microsoft Office right out the box. Down below click the download button to install Microsoft off 2016.
