Solution 1Recommended

Manually Install the Latest Microsoft AutoUpdate Release

Downloading and installing the most recent AutoUpdate package directly from Microsoft can resolve bugs causing the recurring update loop.

Often, the auto-update tool gets caught in a corrupted cache loop where it fails to recognize its own version number. Manually overwriting it with the newest direct installer from Microsoft's official servers can clear this error.

1
Quit Microsoft Applications

Close all Microsoft Office applications running on your Mac, including Word, Excel, PowerPoint, and the AutoUpdate window itself.

2
Visit the Release History Page

Open your web browser and navigate to the official Microsoft Mac update release history page.

3
Download the Latest MAU Package

Locate and download the latest version of the Microsoft AutoUpdate (MAU) installer package.

4
Run the Installer

Double-click the downloaded .pkg file and follow the on-screen prompts to complete the installation process.

5
Restart Your Mac

Restart your Mac to ensure all background update services are refreshed, then monitor if the AutoUpdate prompts continue.

Manually Install the Latest Microsoft AutoUpdate Release
Developer Fix Required: If you are already on version 4.79 or newer and the manual installation does not resolve the looping prompts, this is likely a known bug requiring a developer patch from Microsoft. Report the issue to Microsoft Support providing your exact version and diagnostic details.

Frequently Asked Questions

Can I just uninstall Microsoft AutoUpdate to stop the pop-ups?

While it is possible to delete the Microsoft AutoUpdate application from your Mac's Library/Application Support/Microsoft folder, doing so will prevent your Office apps from receiving critical security and feature updates. It is highly recommended to manually update the tool first to fix the loop rather than removing it entirely.

Where can I find the currently installed version of Microsoft AutoUpdate?

Open Microsoft AutoUpdate on your Mac, click on 'Microsoft AutoUpdate' in the top Mac menu bar next to the Apple logo, and select 'About Microsoft AutoUpdate'. The version number (such as 4.78 or 4.79) will be displayed in the resulting pop-up window.

Why does AutoUpdate think it needs an update when it's already current?

This is usually caused by a caching bug or a corrupted installation file within the AutoUpdate software itself. The app fails to register that the installation was successful, triggering the prompt again. A manual override using the latest installer package from Microsoft's website typically resets this behavior.
