The download page has a link labeled “important hints for OS X (version >=10.7)(DMG)”. That link presently takes you to a page that intimates that installation instructions are coming but otherwise tells you nothing about a Mac installation. OpenOffice is not available from the Apple Store and is not notarized by Apple so you get the error.
Apple has this at the following page: If you want to open an app that hasn’t been notarized or is from an unidentified developer Running software that hasn’t been signed and notarized might expose your computer and personal information to malware that can harm your Mac or compromise your privacy. If you’re certain that an app that you want to open is from a trustworthy source and hasn’t been tampered with, you might be able to temporarily override your Mac security settings to open it. After you've tried to open the app, follow these steps: Open System Settings. Click Privacy & Security, scroll down, and click the Open Anyway button to confirm your intent to open or install the app. In System Settings, choose to open an app despite the security warning if you're certain the app is from a trustworthy source. The warning prompt reappears and, if you're absolutely sure that you want to open the app anyway, you can click Open. The app is now saved as an exception to your security settings, and you can open it in the future by double-clicking it, just as you can any authorized app. This text is from the page at: https://support.apple.com/en-us/102445 Dave -- Dave On November 27, 2025 at 5:58:32 AM, Brian Proffitt ([email protected]) wrote: All: A user's concern was posted on BlueSky[1] about using OpenOffice on a Mac.
