“VATprism” is damaged and can’t be opened. You should move it to the Bin.

Describe the bug
I open dmg and moved the app to application folder and when I want to open the app, warning message displays with the following error:
"“VATprism” is damaged and can’t be opened. You should move it to the Bin."

Macos Version: Ventura 13.3.1

May be a different issue, but did you follow the instructions in the README?

Note: macOS might warn you that VATprism can not be trusted because it has been downloaded from the internet. To open VATprism anyway, right click it and press open. Additionally, after updating, you might receive a message saying the application is damaged and cannot be opened. This is an issue with codesign. Navigate to /Applications/ and run codesign --remove-signature VATprism.app, then start VATprism as usual. I hope to be able to resolve this issue in the future, see the #30 for more information.

Thank you for the reply.

I open up the terminal, navigate to the application directory and run the following command:
codesign --remove-signature VATprism.app

Issue still persists.

That happens because MacOS quarantines the .app files downloaded from Internet, besides being unsigned.

To workaround it you need to remove it from quarantine like this:

From Terminal:

sudo xattr -rd com.apple.quarantine /path/To/VATPrist.app

or

open the folder there the VATPrism is located and press Ctrl + click VATprism.app and select Open from the contextual menu.
