Microsoft prepares users and administrators for changes in Office for Mac support. Office 2019 and Office 365 are expected to offer 'full compatibility' with the new operating system version of macOS 10.15 Catalina in the fall, just in time for the public release date of macOS 10.15, the software group promises.

The office suite can already be used with the beta of Catalina if at least build 16.26 is used with the programs from Office 2019 or Office 365, as it is called in Microsoft's Office Deployment Insiders video channel. Office 2016 runs from build 16.16.11 on under macOS 10.15. The group asks developers to give feedback in case of problems with Word, Excel, Keynote & Co.

• With the release of macOS 10.15 Catalina, Microsoft 365 for Mac and Office 2019 for Mac currently support macOS 10.15, 10.14, and 10.13. For more information, see this article. Support for Office 2016 for Mac will end on October 13, 2020.

Due to the future mandatory Apple notarization of signed apps that are purchased outside the App Store, there may still be error messages during the installation of Office apps in macOS 10.15, notes an employee of the software manufacturer. They want to clear that up until the general Catalina release in autumn.

Office 2019/365 cancel support for macOS 10.12

With the release of macOS 10.15, Microsoft will also discontinue support for macOS 10.12 Sierra, Office 2019 and Office 365 will require at least macOS 10.13 High Sierra. Microsoft already announced last year that Office only supports the three latest macOS versions. Existing Office app installations can still be used under macOS 10.12, but will not receive any updates.

Office 2016 still supported until 2020

Office 2016 for the Mac, however, remains excluded: Due to the older code base, this version should be supported unchanged on macOS from version 10.15 up to OS X 10.10 Yosemite. However, Office 2016 is about to be phased out overall: According to Microsoft, this version will be obsolete as of October 2020, when no more updates will be made available.

Office 2011 before its complete end

A further use of Office for Mac 2011 will not be possible in conjunction with macOS 10.15, the manufacturer notes: Since Apple's upcoming operating system will no longer run 32-bit software, even the old Office applications cannot be opened. Microsoft discontinued support for Office 2011 a good one and a half years ago.
