Any plans for signing macOS packages?

I’m getting this error on macOS Catalina 10.15.3 (19D76) when trying to run a freshly downloaded Duplicacy Web Edition downloaded from (the SHA256 sum matches).

“Duplicacy Web” can’t be opened because Apple cannot check it for malicious software.

I can work around this by clicking “Open Anyway” at System Preferences → Security & Privacy → General → Allow apps downloaded from.

However, it would be nice to get actually signed packages. Any plans for this?


The package is already signed with my developer ID. I just figured out that notarization is what is needed to get rid of the dialog: Customizing the Notarization Workflow | Apple Developer Documentation


The latest version 1.2.1 has been notarized. Can you confirm that it can be opened on your machine now?

Yes, 1.2.1 works perfectly. Thank you!
