How to Access Hidden Diagnostic Menu on Your MacBook

Mac users can sometimes encounter unexpected hardware issues. The operating system crashes, heats fast or strange sounds. It is not easy to find the source of the problem in such cases. Luckily Apple provides a secret tool called Apple Diagnostics for this job.

Apple Diagnostics is a built-in software that scans potential hardware issues on your Mac:

• Accessed by holding D key while closing and restarting Mac
• Controls memory, storage, battery, thermal system and other components
• Shows error codes and descriptions if problems find
• Includes device information such as production date and serial number
• Helps you share test results while troubleshoot with Apple Support

Although access to this diagnostic menu is quite simple, most users are unfamiliar even from the presence of it. This tool is indispensable to understand whether the problem is from software to hardware. If your Mac shows strange behavior, Apple Diagnostics should be the first step to run.

Although technical problems are sometimes severely annoying, Apple has presented robust solutions for such situations. Knowing the diagnostic menu means solving faster problems.
