Introduction: Troubleshooting your Mac is essential to pinpoint and resolve any potential issues affecting its performance. Running diagnostics on your Mac can provide valuable information to help improve the system’s health. Here is a step-by-step guide for conducting a thorough diagnostic test on your Mac.

Step 1:

Shut down your Mac. It’s important to start the diagnostics with your computer turned off for accurate results.

Step 2:

Disconnect all external devices, except for the keyboard, mouse, display, and Ethernet adapter if they’re required for the test.

Step 3:

Turn on your Mac while simultaneously pressing and holding the “D” key on your keyboard.

Step 4:

If you’re using a combination of macOS and Windows (Boot Camp), select your macOS partition when prompted.

Step 5:

You will be asked to choose your language. Once you’ve made a selection, the Apple Diagnostics screen will appear.

Step 6:

Wait for the automatic diagnostic process to complete. It may take several minutes depending on your hardware configuration.

Step 7:

After completion, you’ll receive a list of findings (if any) along with reference codes. Make a note of these codes as you may need them for further troubleshooting.

Step 8:

To get more information about each issue found, click on the downward-facing arrow next to the reference code or press “R” on your keyboard.

Step 9:

Apple Diagnostics provides suggested solutions based on the identified issues. Follow the recommendations and apply necessary fixes accordingly.

Step 10:

If no issues are detected and your Mac is still experiencing problems, consider performing further maintenance like updating software and optimizing settings.

Step 11:

To exit Apple Diagnostics, simply press “Restart” or “Shut Down” depending on whether you want to restart or power off your Mac after finishing the diagnostic test.

Step 12 (Optional):

If required, you can perform an extended diagnostic test by pressing and holding the “Option” key while clicking “Test Again” in the Apple Diagnostics window. Note that the extended test will take significantly longer to complete than the standard version.

Step 13:

If you still experience issues after following the recommended steps, consider seeking assistance from Apple Support or scheduling a visit to your nearest Apple Store.

Step 14:

Keep your Mac updated, clean, and organized as preventative maintenance to minimize the likelihood of running into problems in the future.
