The feature that allows developers to distribute their applications securely is Code Signing. This process involves creating a digital signature for an application using a developer's certificate. When an application is signed with a developer's unique key, it assures users and the operating system that the application comes from a legitimate source and has not been altered since it was signed.

Code Signing plays a critical role in the security model of macOS, as it helps prevent the distribution of malicious software and builds trust between users and developers. If an application isn't signed or if there are discrepancies in the signature, the macOS will typically warn users or block the app from running, thereby enhancing user security.

In contrast, while options like App Store Review and Application Sandboxing contribute to the broader application security ecosystem, they do not specifically pertain to the secure distribution aspect as directly as Code Signing does. FileVault, on the other hand, is focused on encrypting the disk to protect data rather than protecting the application itself during distribution.
