Fix a Stuck Office 2019 for Mac Update and Apps That Will Not Open
Question details
The user needs to complete a stalled Office 2019 for Mac update and regain access to Office applications.
- Product
- Microsoft Office 2019 for Mac and Microsoft AutoUpdate
- Device & OS
- macOS; version not provided
- Scenario
- An Office update stops partway through, preventing the user from opening Office applications.
- Observed behavior
- The update remains stuck for an extended period, and restarting the Mac does not resolve the issue.
Check Apple menu > About This Mac for your macOS version and confirm that you have enough free storage for the installation. Before removing Office, verify that you can sign in to the Microsoft account associated with your license and preserve any locally stored Outlook data or custom templates.
Restart Microsoft AutoUpdate and check the network connection
Use this first when the update appears stalled during downloading or Microsoft AutoUpdate is unresponsive.
If the update is no longer progressing, open Apple menu > Force Quit and close Microsoft AutoUpdate if it is listed. Alternatively, open Applications > Utilities > Activity Monitor, select Microsoft AutoUpdate, and click the stop button. Avoid interrupting an installer that is still actively progressing.
Open System Settings > Network and inspect your connection, VPN, and proxy settings. On older macOS versions, use System Preferences > Network > Advanced > Proxies. Try a trusted alternative network; ask your administrator to check firewall or proxy restrictions on a managed Mac.
In Finder, choose Go > Go to Folder, enter /Library/Application Support/Microsoft/MAU2.0/, and open Microsoft AutoUpdate if it is present. Click Check for Updates and retry the update with all Office applications closed.
If Microsoft AutoUpdate will not launch or continues to stall, visit Microsoft's official support site and find the Microsoft AutoUpdate for Mac download. Download and run the official installer, then reopen Microsoft AutoUpdate and click Check for Updates.
Retry the update in Safe Mode or a new macOS user account
Use these checks to determine whether startup software or settings in your current user profile are interfering with the update.
Completely uninstall Office and reinstall a compatible version
Use this when updater repair and isolation checks do not resolve the problem. Reinstalling Office resolved the reported case.
Keep Working on Office Documents with WPS Office for Mac
WPS Office does not repair Microsoft AutoUpdate, but it provides a free, lightweight alternative for everyday document work while Office is unavailable. Its familiar interface and Microsoft Office format compatibility make it easy to move existing files into WPS and continue working.
Frequently Asked Questions
How can I open Microsoft AutoUpdate if Word and Excel will not launch?
In Finder, choose Go > Go to Folder and enter /Library/Application Support/Microsoft/MAU2.0/. Open Microsoft AutoUpdate from that folder and click Check for Updates. If the app is missing or cannot open, reinstall it using Microsoft's official AutoUpdate installer.
Should I force quit an Office update that looks stuck?
Only consider force quitting when progress has stopped for an extended period and the updater is unresponsive. Use Apple menu > Force Quit or Activity Monitor to close Microsoft AutoUpdate, then reopen it and retry. Do not interrupt an installation that is still progressing.
Is it safe to delete Office folders from the user Library?
Not without checking their contents. Office folders in ~/Library/Containers and ~/Library/Group Containers may contain local Outlook data, templates, and settings. Follow Microsoft's Office for Mac uninstall instructions and remove only the named Office entries after preserving relevant data.
Will reinstalling Office 2019 install the latest supported Office version?
No. Your available installer depends on your license, and Office 2019 is no longer supported. Check your Microsoft account's Services & subscriptions page for installation options. A newer supported Office release may require a new license or subscription and a newer macOS version.
Can WPS Office fix the stuck Microsoft Office update?
No. WPS Office does not repair Microsoft AutoUpdate or activate Microsoft Office. You can use WPS Office for Mac to open supported Word, Excel, and PowerPoint files while troubleshooting Office; check complex formatting and feature compatibility before sharing edited files.
