Fix Microsoft AutoUpdate Stuck at 3 Seconds on Mac
Question details
The user is attempting to install Microsoft Office updates but the process is hanging indefinitely near the end of the installation.
- Product
- Microsoft AutoUpdate
- Device & OS
- Mac
- Scenario
- Installing new Microsoft Office updates via the built-in Microsoft AutoUpdate tool on a new iMac.

Restart Mac and Manually Install the Latest AutoUpdate Package
Refreshing the system and manually applying the newest Microsoft AutoUpdate utility can clear background glitches causing the installer to hang.
Often, the AutoUpdate utility itself is outdated or encounters a background permission conflict on newer macOS versions. Updating the updater tool is the most effective way to resolve this loop.
Press Option + Command + Esc on your keyboard. Select 'Microsoft AutoUpdate' from the list of running applications and click 'Force Quit'.
Click the Apple menu in the top-left corner of your screen and select 'Restart' to clear temporary system cache and stuck processes.
Visit the official Microsoft release notes webpage for Office for Mac. Locate and download the latest version of the Microsoft AutoUpdate (MAU) package.
Double-click the downloaded package file. If the installer does not launch automatically, right-click the file and select 'Open'. Follow the on-screen instructions to complete the installation.
Open any Office application like Word or Excel, navigate to 'Help' in the top menu bar, and click 'Check for Updates'. Proceed with the installation and restart your Mac once it finishes.
Avoid Update Hassles with WPS Office for Mac
If Microsoft AutoUpdate continues to cause freezing issues on your Mac, consider switching to WPS Office. It provides a lightweight, highly compatible, and completely free alternative to Microsoft Office without the cumbersome, error-prone update process.
- 1. Download WPS Office: Visit the official WPS website and download the Mac version of WPS Office.
- 2. Install the Application: Open the downloaded installer and drag the WPS Office icon into your Applications folder.
- 3. Open and Start Creating: Launch WPS Office from your Launchpad, sign in with your preferred account, and open your existing Office files instantly.
Frequently Asked Questions
Why does Microsoft AutoUpdate get stuck at the very end of the process?
This commonly occurs due to a corrupted update cache, background permission conflicts with newer macOS security protocols, or an outdated AutoUpdate utility struggling to finalize the installation scripts.
Can I update Microsoft Office for Mac without using the AutoUpdate tool?
Yes. You can manually download standalone update packages directly from the official Microsoft Office release notes webpage and install them without launching the Microsoft AutoUpdate tool.
Will force quitting a stalled Microsoft update corrupt my Office apps?
Generally, no. Force quitting prevents the updater from hanging indefinitely. However, if the main Office applications fail to launch afterward, you may need to download the full Office installer from Microsoft to repair them.
How do I completely remove the Microsoft AutoUpdate tool from my Mac?
Open Finder, press Command+Shift+G, and go to /Library/Application Support/Microsoft/. Drag the MAU2.0 folder to the Trash and empty it. Be aware that doing this prevents future automatic updates for Office apps.
