Microsoft Office 2016 For Mac High Sierra

Thank you for choosing our product. Based on your description, you want to use Office 365 desktop applications on Mac OS Sierra. However, due to the continuous update of Office 365 products and the launch of Mac OS Catalina, Office 365 is no longer supported in Mac OS Sierra. Even if it can be installed, unexpected problems may occur. I'm wanting to know if there is a Microsoft office version that will run on macOS high Sierra 10.13.6 Microsoft Office Technician: Tech-Expert, Microsoft Software Expert replied 6 months ago Yes, you can use Microsoft Office 365. Well the latest Office 2019 (Nov 10) was released prior to Big Sur (Nov 12). I guess it's possible that Microsoft may end up blocking Office 2019 updates on High Sierra. If not, if you can figure out the url they get the updates from it should be possible to figure out a way to block the update prompts. To provide you with the best experience, Microsoft 365 for Mac and Office 2019 for Mac supports the three most recent versions of Apple's macOS. Note: As new major versions of macOS are made generally available, Microsoft will remove support for the oldest version and support the newest and previous two versions of macOS. Choose the right Microsoft 365 subscription for your Mac. Includes the latest AI-powered Office apps, 1 TB of cloud storage, and premium mobile features.
