Word for Mac not always closing files in OS 26

In Word for Mac, with files that have been open for several hours, when I close the file it looks like it closes then immediately opens again. And the finder shows it was not saved.

MacBook Air 13″, macOS 26.0

Microsoft 365 / Office / Copilot / Word is a third-party app. Check for updates, and then check with the Microsoft support forums.


Whether this is an Office bug or an issue with macOS 26, Microsoft is in the best position to address it or to report it to Apple.


There are some fine alternative apps available that can read and write Office documents and that don’t involve Microsoft apps, as well. LibreOffice, and the Apple iWork apps can read and write many Office documents, too.
