enter image description here

I have selected "App store an identified developers" in the security setting

there is supposed to be an "Allow Anyway" button that appears when I try to open the non-identified app.

However, this button does not appear. See the modal side-by-side with the setting from the settings panel

    What do you see if you right-click > Open ?

  • The same result: A message saying the app is blocked and offering my only "Cancel" and "Move to Trash". Despite all of the online docs saying that right-click to open will bypass the security quarantine, this appears not to be true any longer for Ventura.

  • Where did you download the application from? Providing a link might help others to check for themselves what might be wrong here.

MacOS flags the "This app is damaged" alert when the digital signature is invalid. This is usually the case if the file has been modified in some way after signing; but it could also be an issue with the certificate used to sign the app. (E.g. expired, pulled.)

You should try re-downloading the app; and if that fails, contact the developers.

This is a different issue from a quarantine flag, which usually just alerts the user that the app has recently been downloaded and is from an unknown developer: but you are normally still given the possibility to open it.

If deleting the quarantine flag did indeed fix it, then it could well be a bug, and you should report it to Apple.

It is because the "Google Chrome for Testing" file is damaged, so it can't be opened. It is not being blocked by security, but the file is corrupted. To un-corrupt the file, I would recommend to re-install the application.

the only known fix that I have found to this problem is to run this special command to de-quarantine the app

xattr -d com.apple.quarantine /Applications/Google\ Chrome\ for\ Testing.app/

update 2024-02-02 macOS Sonoma 14.1.2 now tells me : xattr: /Applications/Google Chrome for Testing.app/: No such xattr: com.apple.quarantine

however, the actual bug (the absence of the "Allow anyway" button) appears to be fixed in the OS
