Scenario
Attempting to install, run, or update Microsoft Office applications on an older Mac operating system.

Solution 1Recommended

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.

1
Download Microsoft AutoUpdate

Download and install the most recent version of the Microsoft AutoUpdate package that is still supported on macOS Sierra.

2
Open an Office Application

Launch an existing Office app on your Mac, such as Microsoft Word, Excel, or PowerPoint.

3
Check for Updates

Click on the 'Help' menu in the top Apple menu bar and select 'Check for Updates'.

4
Install Available Updates

Allow the AutoUpdate tool to search for and install the maximum allowed Office version for your current macOS.

Update Limitations: Because macOS Sierra is no longer officially supported by Microsoft, you will not be able to install the latest modern Office builds. Your software will max out at an older build, typically around version 16.30.
