How to quickly test your Mac’s hardware

Apple offers a simple way to check the hardware of your Mac by running a diagnostic test. I recommend you run this to see if there are any issues with your logic board, memory or other hardware. The test only takes a few minutes.

Shut down your Mac and unplug everything except for your mouse, keyboard, monitor and Internet connection. Power up your Mac and immediately after pushing the power button, press and hold D on your keyboard. Hold it down until either Internet Recovery or the Apple diagnostic icon appears. Eventually, you will be asked to select your network. This will be the name of your Wi-Fi and password. Next, you will be asked to select a language. Use your mouse or arrow keys to choose and then select the arrow at the bottom to continue.

Once the diagnostic test appears, it will first automatically begin examining your Mac and you cannot start any tests until this is finished. Once it is done, select the Test button to begin.

The test takes a few minutes to complete and when it does, it will either indicate that no trouble was found with your hardware or it will reveal codes that you can use to either troubleshoot your Mac yourself, or you can take these codes to Apple or your technician so they can help get your Mac back on track.

If you would like to run a more thorough test, checkmark the box: “Perform extended testing” and then select the Test button. This test will take longer to perform so leave yourself enough time for it to complete. When it is finished, look below for the details of the scan. Again, if there are issues, it will show codes that can be used to help repair your Mac.
