Just before the official release of macOS Catalina, Apple is asking developers to submit macOS Catalina apps to the App Store.

The company aims to encourage developers to take advantage of macOS Catalina technologies like Sign in with Apple, Sidecar, Core ML 3, and Metal. In addition, Apple highlights Mac Catalyst, especially created to bring iPad applications to the Mac.

“macOS Catalina will soon be available to hundreds of millions of users around the world. With macOS Catalina, your Mac apps can take advantage of Sign in with Apple, Sidecar, and the latest advances in Core ML 3, and Metal. And with Mac Catalyst, you can bring your iPad apps to Mac. Build your apps using Xcode 11, test them on a Mac computer running the macOS Catalina GM seed, and submit them for review.“

Apart from submitting their new applications, Apple has reminded developers of a new notarization requirement for apps which are designed for distribution outside of the App Store.

The company requires applications that are distributed outside of the App Store to be notarized by Apple to run on macOS Catalina.

The notarization process that was first introduced in macOS Mojave, is aimed at protecting Mac users from malicious and harmful applications.

“To further protect users on macOS Catalina, we’re working with developers to make sure all software, whether distributed on the App Store or outside of it, is signed or notarized by Apple. This will give users more confidence that the software they download and run, no matter where they get it from, has been checked for known security issues.

In June, we announced that all Mac software distributed outside the Mac App Store must be notarized by Apple in order to run by default on macOS Catalina. Make sure to test all versions of your software on the macOS Catalina GM seed and submit it to Apple to be notarized.”

For notarization, Apple offers Developer IDs to trusted non App Store developers required to let the Gatekeeper function on macOS install non Mac App Store apps.

Applications which are distributed through the Mac App Store do not require notarization, and Apple has recently relaxed its notarization rules, allowing developers to comply until January 2020.

Yesterday, the company launched the golden master version of macOS Catalina to developers, which represents the final version of the software that will be provided to the public this month.
