The primary purpose of App Extensions in macOS (formerly known as OS X) is to allow apps to offer their services and capabilities in other contexts and applications, particularly in areas like the Today View. By enabling functionalities that can be accessed directly from the Today View, App Extensions enhance user experience by providing quick access to app-specific information and tools without needing to switch between different applications. For instance, a weather app could present a widget in the Today View, providing real-time weather updates right on the user’s dashboard, without launching the complete application.

Other options do not represent the main function of App Extensions. For instance, while improving network connectivity and enhancing security features are vital aspects of operating systems, they do not directly relate to how App Extensions operate. Similarly, enabling external applications to run independently refers more to the execution capabilities of applications rather than the interaction and enhancement features provided by App Extensions. Thus, the correct answer highlights the specific role App Extensions play in customizing and enhancing user interfaces through the integration of features and information across different parts of the macOS system.
