What tool can be used to diagnose hardware issues on Apple Macs?

Apple Diagnostics is the appropriate tool for diagnosing hardware issues on Apple Macs. This utility is specifically designed to test the hardware components of the Mac and to detect any potential problems that may affect the system's performance or functionality. When users run Apple Diagnostics, the tool checks various aspects of the hardware, including the logic board, memory, and other critical components, providing error codes and descriptions that can help identify issues.

The other options, while they serve important purposes, are not primarily focused on diagnosing hardware issues. For instance, Disk Utility is mainly used for managing disks, repairing file systems, and formatting drives, rather than performing comprehensive hardware diagnostics. The System Profiler provides detailed information about the hardware and software configurations of the Mac but does not diagnose issues. Meanwhile, Mac Health Checker is not a recognized standard tool in macOS for hardware diagnostics. Therefore, Apple Diagnostics stands out as the dedicated solution for such needs.
