Apple requires all submitted software must meet the original notarization prerequisites in February

At the developer conference (WWDC 2019) in June this year, Apple announced to the world that it would resume the application verification requirements for macOS Catalina to ensure the safety of end-users. The new policy will begin in February 2020, and the transition period will affect macOS software released through non-Mac app stores.

In an article on the Apple Developer website, the company confirmed that:

 In September, we temporarily adjusted the notarization prerequisites to make this transition easier and to protect users on macOS Catalina who continue to use older versions of software. Starting February 3, 2020, all submitted software must meet the original notarization prerequisites.

The new policy requires developers to submit applications to Apple for pre-review to verify their security, otherwise, they will not run in macOS Catalina. As an extension of the current Gatekeeper process, Apple has now made this optional item a mandatory requirement to ensure that downloaded software comes from a user’s trusted source, and Apple will automatically scan certified applications for security issues or malicious code.
