System cleanup in one click

We associate a Mac with quality, capacity, speed, and reliability. But it might happen so that your Mac underperforms and unpredictable issues occur. Before taking it to the nearest Apple service, you can try to identify the problem by yourself. That will save your time and money, and prevent serious system crashes. Identifying whether the issue is a hardware or software one will determine the possible actions and next steps.

When we deal with the hardware problem, the first thing to try is to perform Apple Diagnostics (or Apple Hardware Test). It will help you reveal the process that causes the problem and lowers Mac productivity.

Apple Diagnostics is an easy-to-understand tool that provides detailed results and suggestions with the next steps. Whether you are a techie or not, you'll get everything easily.

What is Apple Diagnostics?

Apple Diagnostics is a built-in test that helps detect what hardware components are causing the problem, and find system failures. The test checks RAM, power controller, logic board, battery, and other wireless modules.

That was the hard part. And the easy part is that you can run Apple Diagnostics in just a few steps. The whole process will take about 2-5 minutes — but ultimately saves hours of your time.

A great feature of Apple test is that after hardware checking, it displays an error code, offers you clear solutions, and the assistance of Apple Support. You can write out the error codes (known as reference codes), and either do the research on/ your own or contact Apple.

When referring to Mac hardware test, you might also hear about Apple Hardware Test (AHT). This is an older brother of Apple Diagnostics (AD), and they have some minor differences. Mainly, the results of AHT aren't conclusive and descriptive. AHT is used in Macs released in 2012 or earlier, while AD is a more advanced analog that works with newer Macs.

Essentially, a Mac hardware test is the great tool to help you understand the problem. And if it doesn't have a fix for it — there are more advanced tools that you can use to troubleshoot Mac issues. More about that in a moment.

How to run Mac diagnostics

Running a hardware test on Mac may seem like a complicated process, but believe us — that's not:

1. Disconnect all the peripheral devices (printer, cables, external DVD drive) except the keyboard, mouse, display, and speakers. Make sure your Mac is connected to mains power and the internet.
2. Select Apple Menu > Restart
3. Press and hold the D key until you see a list of different languages on the screen
4. Select a language. Apple Diagnostics starts automatically.
5. Wait for about 2-5 minutes until the checking is completed. If any problems are found, you'll see the options of solutions and an error code.

After that, you can either repeat the test, get more information, restart or shut down the Mac. That's it - an easy 5-step process, as promised.

Apple recommends to print out the instructions to keep them close at hand and make sure you don't miss any step. Or, you can take a photo. Right, that's what people do in 2021.

What are the common Apple Diagnostics results

After performing a Mac hardware test, you'll get the list of found issues with detailed descriptions and related reference codes.

However, to fix a specific problem, Apple Diagnostics might recommend you to contact Apple or take your Mac to an Apple Authorised Service Provider or AppleRetailStore.

There could be the case the system testing doesn't find any issues.

In this case, you have a few options. Please note that they are mutually exclusive, which means you should choose the best option for you:

2. A part of the diagnostics system can be damaged. You can solve the problem by restarting the Mac while holding down Option+D. This will start an internet-based hardware test.
3. Firmware password might be the problem. Make sure you turn it off while performing hardware testing.

I have a absolutely perfect used 1 time mac tools ET-975 diagnostic oscilloscope, it has every cable and accessory, I purchased this years ago to use in the automotive shop I worked in and then our state implemented a new emission testing program and the owner purchased a new emissions analyzer with a oscilloscope built in, so I took this home and it's been in my basement every since. I paid $ 1969.00 + tax for this unit. I have retired from automotive repair and don't see ever using this again. This is portable and works off a vehicles own battery, it does all kinds of testing including multi-port fuel injectors. Live CRT waveforms, parade, raster,superimposed and alternator testing. Has 10' foot leads with screw on connectors. This is as new as the day I bought it, I checked it two months ago realizing I might list it and works perfect!! It's a big loss for me to sell but I'll never use it so here it is. You will be 1000% happy with this!!. Hot Rodders and Racers can use it right in the garage or track. I'm a perfectionist and I respect you wanting a perfect oscilloscope. I will have to include insurance for $100.00 over whatever it sells for just in case, I will document in person at UPS center with pictures taken for insurance purposes. I am also going to include a brand new set of Thexton ignition and test adapters still in original packages and case. Save this to your watch list because I'm going to add pictures later I just don't have time right now, I also have the dust cover, it's a little yellowed you know how vinyl is. Shipping will be to lower 48 only and I'm going to have to find a special box so I'm requesting a little more time to ship..I know this is a lot of money and I can understand if someones nervous but no worries it's going to be covered, comes with free new Mac Cap...Thanks
