How to Use Apple Diagnostics on Mac to Identify & Troubleshoot Hardware Problems

If your Mac is experiencing unusual problems that you suspect may be a result of a hardware issue, using Apple Diagnostics may help to identify and even troubleshoot a problem.
Apple Diagnostics will run a suite of tests on the Mac to check for hardware issues – meaning, not a problem with system software, but instead it searches for trouble with some sort of hardware component on the Macintosh. For example, if a port is no longer working, a battery has failed, an issue with the graphics card or display, things of that nature that are not related to system software or software related trouble.
