Hello, thank you for reaching out to Microsoft Q&A.

Microsoft 365 for Mac, Office 2024 for Mac, and Office 2021 for Mac support the three most recent major versions of Apple’s macOS. As of September 2025, those versions are macOS Tahoe, macOS Sequoia, and macOS Sonoma.

If you’re running the latest version of macOS and still receiving this error, please try reinstalling the Office apps and check whether you continue to experience the same problem.

1. Quit all Office applications.
2. Open Finder > Applications.
3. Use Command button +click to select all of the Microsoft 365 for Mac applications.
4. Ctrl+click the application you selected and click Move to Trash.

Once done, in the Finder, click GO in the menu bar and go to folder - ~/Library/Containers/

Delete the folders starting with,

com.microsoft.Word

com.microsoft.Excel

com.microsoft.Powerpoint

com.microsoft.Outlook

com.microsoft.OneNote

Go back to the Library folder and open Group Containers. if present, and Move to Trash.

If Word is not opening on your Mac after installing Office Home 2024, it could be due to compatibility issues with your version of macOS. The error message you are seeing suggests that the application may not be compatible with your current macOS version. Here are some steps you can take to troubleshoot the issue:

1. Check Compatibility: Ensure that Office Home 2024 is compatible with your version of macOS. You can check the official Microsoft website for compatibility information.
2. Reinstall Office: Sometimes, reinstalling the application can resolve issues. Uninstall Office completely and then reinstall it from your Microsoft account.
3. Update macOS: Make sure your macOS is fully updated, as updates can sometimes resolve compatibility issues.
4. Contact Support: If the problem persists, consider reaching out to Microsoft support for further assistance.

These steps should help you determine the cause of the issue and potentially resolve it.
