Even the brilliantly designed Mac is not infallible when it comes to technical glitches and configuration problems. When you purchase a new Mac device, it runs beautifully without hiccups. However, as time passes, you may notice that your device has substantially slowed down, lags between intervals, or has a few glitches that need to be addressed. Most of them can be solved easily using the help of Apple’s assistance, however, it can be possible that you are remedying the symptoms and not the cause of such tech problems.
To help you find the root of the glitch, Mac has a built-in feature that helps you to find errors and problems within the system without you having to download any external scanners. This nifty function is Apple’s diagnostic tool that comes with the perks of running complete system scans and deep scans to detect and configure hardware issues.
Apple Diagnostics to the Rescue
Apple Diagnostics is a tool to help you scan your Mac device for faulty hardware. The diagnostic test will display all the hardware pieces of your Mac that could potentially have problems while giving you the information required to understand the glitch and fix it.
Apple Diagnostics was added to every Mac model post June 2013. Older Mac devices have a similar feature known as Apple Hardware Test (AHT), which works like Apple Diagnostics. If you don’t know how to check it, you can look up your model number using the Apple device information in the settings.
If your Mac’s scan shows that your device has faulty hardware, the reference codes shown in the results will help you resolve it. If your device needs professional assistance, you can show it to the service center after trying to fix the error yourself with this tool.
Apple Diagnostics is easy to use online and offline, but you have to get a few things set up first.
- Ensure that your Mac device lies on a hard and flat surface with appropriate ventilation.
- Shut down your Mac device.
- Disconnect any attached external devices except for your keyboard, mouse, broadband connection, and power cord.
- Turn off all firmware passcodes your device has.
How to use the tool
- Press the Power button to stitch on your Mac device.
- Immediately press and hold D on the keyboard. If pressing D doesn’t work, use Option + D
- Release the key when you see the progress bar, a little globe, and a message displaying “Your Mac is searching for an internet connection” or asks the user to choose a language.
If you own an M1 Mac, follow the steps below:
- Switch on your device and keep holding the Power button while it starts.
- When the startup options appear, release the Power button.
- Press Command + D
You can use the displayed error codes to know more about the problem and find all possible solutions to the issue. To understand the meaning of such codes, refer to the Apple Diagnostics reference codes.
With these simple steps, your Mac can diagnose and help resolve any detected problems!
