<-- Loop back to User Action
Step-by-Step Trace - 10 Steps
Step 1: Power on the Mac hardware
Step 2: Load the bootloader program
Step 3: Initialize the kernel
Step 4: Start system services
Step 5: Launch the user interface (Finder)
Step 6: User performs an action (e.g., open an app)
Step 7: Process the user request
Step 8: Update the display with new information
Step 9: Check if the user wants to perform more actions
Step 10: User chooses to shut down

This diagram shows the layered structure of macOS: hardware at the base, managed by the kernel, supported by system services, topped by the user interface (Finder), which interacts directly with user actions.
Flowchart Quiz - 3 Questions
Test your understanding
What is the first step when starting macOS?
AProcess user request
BLaunch the user interface
CPower on the hardware
DShutdown macOS
Key Result
macOS works by starting hardware, loading its core kernel, running essential services, then providing a user interface to handle user commands smoothly.
