What is Apple Diagnostics primarily used for?

Apple Diagnostics is primarily designed as a customer-facing utility that provides a comprehensive assessment of a Mac's hardware components. This tool assists users in identifying potential issues with various hardware systems such as memory, storage, and other critical components. By running a series of tests, Apple Diagnostics offers a clear report of any detected problems, making it user-friendly for individuals who may not have technical expertise.

The other choices, while related to diagnostics, do not accurately represent the primary function of Apple Diagnostics. For instance, it is not exclusively a tool for iOS devices, nor is it limited to Mac mini Servers or designated for backend use by authorized service providers. Apple Diagnostics aims to empower users to quickly diagnose hardware issues on their own without requiring extensive technical knowledge or access to specialized resources.
