Microsoft has given some guidance about Office for Mac support on the upcoming MacOS ‘High Sierra’ 10.13. But not without a little encouragement to buy the Office for Mac.

High Sierra will be publicly released in the (northern) autumn and some testers will have it already. There will be a public beta release later in June 2017.

Microsoft says it hasn’t tested Office 2011 for Mac on High Sierra and no support will be provided.

They point out that support for Office 2011 ends in a few months, on 10 October 2017.

On the other hand, it’s hard to believe that the Office for Mac team hasn’t devoted some effort to testing Office 2011 on the upcoming macOS. Aside from the support deadline, Redmond has a vested interest in getting anyone with Office 2011 to hand over more money for Office 2016/Mac. Staying quiet on compatibility of Office 2011 serves Microsoft’s ends.

Apple is changing the entire disk/file system which is a major change that needs careful testing for programs like Office. Gone is the 30-year-old HFS+ system in favor of APFS Apple File System.
