Did you know that your Mac has a magic tool that can help you know if something is going wrong? It's called the Apple Diagnostic Tool! It's like a doctor for your computer. Here I explain, step by step, how to use it.
What is the Apple diagnostic tool?
It's a tool that checks if there are any problems with important parts of your Mac, such as the memory or the processor (the brain of the computer). If something is wrong, it tells you so you can fix it.
How to use it step by step
1. Get ready
Put your MacBook on a clean, flat table. Don't connect anything extra, such as chargers, USB or external drives, just the keyboard and mouse if you need them.
2. Restart your Mac in diagnostic mode
If your Mac is one of the older ones (with Intel):
- Turn off your MacBook.
- Turn it on and, as soon as you see the black screen, press the key. D until a menu for language selection appears.
If your Mac is one of the newer ones (with M1 chip or higher):
- Turn off your MacBook.
- Turn it on and hold down the power button until you see the options window.
- Select Options and then Apple Diagnostics.
3. Choose a language
Use the arrow keys to select the language you speak and press Enter.
4. Let the tool work
The tool will start checking your Mac automatically. This may take a few minutes, so be patient.
5. Check the results
When it is finished, you will see on the screen if it found any problems. If there is a weird code (like ADP000), write it down! You can look up what it means on Apple's support page or tell a technician.
What else can you do?
- If there are no problems: Great! Just keep using your Mac normally.
- If there are problems: Connect your Mac to the internet for more ideas on what to do or call Apple support.
- Extra tests: If you think the problem is with the programs (not the hardware), turn your Mac on at Safe Mode to check it.
With this tool, it's easy to find out what's wrong with your Mac and fix it, so it will always run like new!
