Office 2019 for Mac Will Lose Editing Abilities as Certificate Expires
Microsoft will disable editing in Office 2019 apps for Mac starting July 13 due to an expiring digital certificate, though users can still view and print existing documents. A renewed certificate exists but can only be applied via a software update, so Office 365 and Office 2021 remain unaffected. macOS 12 Monterey+ users should update to build 16.83; iPhone/iPad users on iOS 17+ need build 2.93. If you can’t update, you can use Microsoft 365 web apps or upgrade to Office 2024. Office 2019 support ended in Oct 2023, and critics say the expiry effectively retirement of older software; alternatives include LibreOffice or Apple iWork.
