Successfully completing Kernel initialization during startup is a critical step in the boot process of an operating system. When the Kernel initializes, it sets up the essential components required for the operating system to function properly. This includes detecting and configuring hardware, loading necessary drivers, and preparing system resources.

Once this process is successfully completed, the system is considered operational and ready for use. At this point, the operating system can start executing user-level processes and applications, allowing the user to interact with the system effectively. This operational readiness is a prerequisite for higher-level processes to begin, such as launching the user interface and various services.

In contrast, while the graphical user interface does appear after the kernel initializes, it is not the direct result of this completion; instead, it is one of the next steps that occur. The system does not shut down following kernel initialization, nor does the Launchd process begin until after the system is fully operational. Thus, the successful completion of the kernel initialization signifies that the system has transitioned to a state where it can execute user commands and manage resources effectively.
