Verify Office Version and Update Microsoft AutoUpdate
Check your current Office 2016 version and manually install the latest Microsoft AutoUpdate to ensure compatibility with your current macOS.
A perpetual (lifetime) Office 2016 license is a one-time purchase. It receives security and stability updates for its specific lifecycle but does not automatically upgrade to a major newer version like Office 2019 or Microsoft 365.
Update problems often occur when legacy Office installations conflict with the current software, or when the Microsoft AutoUpdate tool itself becomes outdated.
Open the Applications folder on your Mac, right-click a Microsoft application such as Microsoft Word, and select 'Get Info' to check the version number. Ensure it is at least version 16.16.27, which supports Catalina and Big Sur.
Check your Applications folder for older Office installations, such as Office 2011, 2008, or 2004. Move these obsolete folders to the Trash and empty it to prevent system conflicts.
Download the current Microsoft AutoUpdate package from the official Microsoft website. Double-click the downloaded package file to install it.
Open Microsoft AutoUpdate from your Applications folder to bring Office 2016 to its latest supported update level. Once the process is complete, restart your Mac.
Switch to WPS Office for Seamless Mac Updates
Instead of struggling with outdated software or paying for an expensive Microsoft 365 subscription, switch to WPS Office. It provides a lightweight, perpetually updated, and free alternative that runs perfectly on macOS.
Frequently Asked Questions
What is the difference between a lifetime Office license and a Microsoft 365 subscription?
A lifetime (perpetual) license is a one-time purchase that stays on the version you bought (like Office 2016) and does not receive new feature upgrades. Microsoft 365 is a subscription service that constantly updates with the newest tools and features.
Does Office 2016 work on macOS Big Sur?
Yes, Office 2016 for Mac version 16.16.27 is compatible with macOS Catalina and Big Sur. However, because it has reached the end of its support lifecycle, it will not receive further patches from Microsoft.
Why is Microsoft AutoUpdate failing to open on my Mac?
Your Microsoft AutoUpdate tool may be outdated or conflicting with legacy Office apps. Downloading the latest updater package directly from Microsoft and removing old installations usually resolves this issue.
Can I upgrade my Office 2016 to Office 2021 for free?
No. Because Office 2016 is a perpetual license, upgrading to a newer perpetual version like Office 2019 or Office 2021 requires purchasing an entirely new license.
