- Product

- Device & OS
- macOS
- Scenario
- Attempting to create or edit documents in Word, Excel, or PowerPoint after installing a newly purchased Office 2019 license on a Mac.

Remove Previous Licenses and Clear Keychain Identities
Clear out old or conflicting Microsoft 365 license files that are overriding your new Office 2019 perpetual license.
When an older Microsoft 365 subscription or trial was previously installed on your Mac, the system often prioritizes those cached license files over your new perpetual purchase. Cleaning these hidden files will force the application to recognize your permanent Office 2019 license.
Open Excel or Word, sign out of your current Microsoft account, and then completely quit all Microsoft Office applications.
Open Finder, navigate to Applications > Utilities, and launch 'Keychain Access'. Search for and delete any entries related to 'Microsoft Office'.
Download and run the official Microsoft Office license-removal tool for Mac to completely clear hidden subscription and activation files.
Restart your Mac, open Excel or Word, and sign in with the exact Microsoft account used to purchase Office Home & Student 2019.

- 2. Install the application: Open the downloaded package and drag the WPS Office icon to your Applications folder.
- 3. Start creating instantly: Launch WPS Office and immediately open, edit, or create documents without complex activation steps.
Frequently Asked Questions
Why is my Mac asking for a Microsoft 365 subscription when I bought Office 2019?
This usually happens if a previous Microsoft 365 trial or subscription was installed on your Mac. The system prioritizes the cached subscription license over your new perpetual Office 2019 license.
Will using the license removal tool delete my Word documents or Excel spreadsheets?
No, the license removal tool only deletes hidden activation and licensing files. It does not touch or modify any of your personal documents, spreadsheets, or installed applications.
What if the license removal tool doesn't fix the activation prompt?
If the issue persists, ensure that you are signing in with the exact Microsoft account associated with your Office 2019 purchase. You may also need to uninstall the Office suite completely and reinstall it directly from your Microsoft account dashboard.
Can I use a Windows Office 2019 product key on my Mac?
No, Microsoft Office 2019 licenses are operating system specific. An 'Office Home & Student 2019' license must explicitly state it is 'for Mac' to activate on macOS devices.
