Vectorworks 2019 plugin with Catalina macOS

I’m now having an issue with the plug in as Apple is saying it cannot check it for malicious software. As soon as I open Vectorworks, it gives me a warning. (Screen grab attached)

It is a beta version of the OS so I understand, but it says to « contact the developer for more information » so that is what I am doing.

Hopefully this is something easy to fix.

Thank you,



Thanks for your message.
It might be because the plugin is not signed and Catalina needs signed items.
We will sign it and send it to you to test it.
Can you send me your email address at

Best regards,
