Fix Microsoft AutoUpdate Asking for Latest macOS After Office 2019 Upgrade
Question details
The user is experiencing incorrect macOS update prompts from Microsoft AutoUpdate after upgrading to Microsoft 365, as the system still identifies the installation as Office 2019.
- Product
- Microsoft Office for Mac
- Device & OS
- macOS
- Scenario
- Upgrading from an older Office 2019 perpetual license to a new Microsoft 365 subscription on a Mac.
- Observed behavior
- Microsoft AutoUpdate continues to label the product as Office 2019 and incorrectly asks the user to update to the latest macOS, preventing proper software updates.
Ensure you have your Microsoft 365 account credentials ready and save all open documents before beginning the uninstallation and license removal process.
Clear Old Licensing Files and Reinstall Microsoft 365
Use the official Office License Removal Tool to delete conflicting Office 2019 data and perform a clean installation of Microsoft 365.
When upgrading to Microsoft 365, older Office 2019 license files can remain securely cached on your Mac. This causes Microsoft AutoUpdate to read the wrong product version and trigger incorrect macOS update prompts.
Open the Finder, go to the Applications folder, and move all Microsoft Office applications (Word, Excel, PowerPoint, Outlook) to the Trash.
Download the official Office License Removal Tool from the Microsoft support website, open the .pkg file, and follow the on-screen prompts to clear your Mac's license cache.
Click the Apple menu in the top left corner and select Restart to ensure all cached files are completely cleared from the system memory.
Log in to your Microsoft account online, navigate to your subscription dashboard, and download the latest Microsoft 365 installer for Mac to install the current suite.
Open Microsoft Word, click on 'Word' in the top menu bar, and select 'About Microsoft Word'. Verify that the license now shows 'Microsoft 365 Subscription' instead of Office 2019.

Frequently Asked Questions
Why does my Mac still show Office 2019 after buying Microsoft 365?
This happens because macOS securely caches old licensing files. Even if you install a new app version, the system prioritizes the cached license. Running the official Office License Removal Tool clears these old files so the new Microsoft 365 license can be applied.
Will uninstalling Office for Mac delete my documents?
No, uninstalling the Office applications by moving them to the Trash only removes the software files. Your personal documents, spreadsheets, and presentations saved locally on your Mac or in cloud storage will remain completely intact.
What if Microsoft AutoUpdate still asks for a macOS update after reinstalling?
Ensure your macOS version meets the minimum requirements for the latest Microsoft 365 apps. If your Mac is too old to support the newest macOS, you may need to rely on an older build of Office or switch to an alternative like WPS Office which supports a wide range of macOS versions.
