What tool can be used to diagnose hardware issues on a Mac?

Apple Diagnostics is specifically designed to help users identify hardware issues on a Mac. When you run Apple Diagnostics, it performs a series of tests on your Mac’s hardware components, such as the memory, logic board, and graphics card, and provides error codes if it detects any problems. This tool is essential for troubleshooting hardware failures since it focuses on testing components that may fail, allowing users to get a clear understanding of potential issues that need further attention or repair.

In contrast, Disk Utility is primarily used for managing disks and file systems, such as formatting, partitioning, or repairing drives, rather than diagnosing hardware malfunctions. Activity Monitor serves as a performance-monitoring tool, providing insights into CPU and memory usage, active processes, and system performance, but it does not test hardware components specifically. Terminal is a command-line interface that allows users to perform various tasks on their Mac, but it requires more advanced knowledge and does not provide a focused hardware troubleshooting solution like Apple Diagnostics.
