I've been using Sigil 1.3.0 on macOS Catalina for some time now without any problems and still can.

Thinking of starting a new project using the latest stable Sigil, I downloaded 1.5.1, moved it to the Desktop, and used Terminal.app (as per the instructions changing only the package name in Terminal to Sigil.app-1.5.1-Mac.txz) to create an executable.

No problems were indicated in Terminal, so I renamed the resulting app to Sigil 1-5-1.app (I've kept older Sigil versions with this convention in case there is a problem with a new version), and moved it to my Applications folder.

When I double click on Sigil 1-5-1.app I get the following message:

------------------------------------------------
“Sigil 1-5-1.app” can’t be opened because Apple cannot check it for malicious software.
This software needs to be updated. Contact the developer for more information.
Safari downloaded this file today at 12:16 PM.

The developer website directed me here to note my issue. Does anybody have any suggestions regarding this problem?

Thank you,
