If you try to use Office 2016 for Mac v15.34 or before, you may be stopped.
That means you’ll have to update your current Office 2016 for Mac before switching to High Sierra. “Not all Office functionality may be available, and you may encounter stability problems where apps unexpectedly quit. “ Beyond that there’s a broad level of caution Microsoft will only say that v15.35 will install. That’s interesting because the current public release of Office/Mac is v15.34 (0.01 less) – even the latest Office isn’t officially ready for the upcoming Mac release. Microsoft says Office 2016 for Mac version 15.35 or later will install on MacOS 10.13. The new MacOS has one major change so Microsoft’s caution about Office compatibility is understandable. There will be a public beta release later in June 2017. High Sierra will be publicly released in the (northern) autumn and some testers will have it already.
But not without a little encouragement to buy the Office for Mac.
Microsoft has given some guidance about Office for Mac support on the upcoming MacOS ‘High Sierra’ 10.13. Thanks for joining us! You'll get a welcome message in a few moments.
