Compatible Microsoft Office Versions for macOS Sierra 10.12.6
Question details
The user needs to know which version of Microsoft Office can be successfully installed or updated on a Mac running the older macOS Sierra 10.12.6 operating system.

- Product
- Microsoft Office for Mac
- Device & OS
- macOS Sierra 10.12.6
- Scenario
- Attempting to install, run, or update Microsoft Office applications on an older Mac operating system.
- Observed behavior
- The current Office version is outdated (e.g., 16.29.1), and newer Office builds refuse to install or update because they require a more recent macOS version.
Before attempting to install older Office builds, check your exact Mac model to see if it supports upgrading to a newer macOS version, which would allow you to run the latest Microsoft Office releases securely.
Use Microsoft AutoUpdate to Find Compatible Versions
By installing the Microsoft AutoUpdate tool, your Mac will automatically detect and install the highest supported Office version specifically allowed for macOS Sierra.
Microsoft AutoUpdate (MAU) manages application updates for Office on a Mac. If you are on an older operating system like Sierra 10.12.6, MAU recognizes this and caps the updates at the final version supported by your OS.
Download and install the most recent version of the Microsoft AutoUpdate package that is still supported on macOS Sierra.
Launch an existing Office app on your Mac, such as Microsoft Word, Excel, or PowerPoint.
Click on the 'Help' menu in the top Apple menu bar and select 'Check for Updates'.
Allow the AutoUpdate tool to search for and install the maximum allowed Office version for your current macOS.
Upgrade macOS to Support Newer Office Builds
If your Mac's hardware permits, upgrading the operating system is the most secure way to run current Microsoft Office versions.
Try WPS Office for Your Older Mac
If your Mac cannot run the latest Microsoft Office updates due to macOS Sierra restrictions, WPS Office offers a free, lightweight, and highly compatible alternative that works seamlessly on older Apple hardware.
