After isolating an issue on your Mac to a possible hardware issue, you can use Apple Diagnostics to help determine which hardware component might be causing the issue. Apple Diagnostics also suggests solutions and helps you contact Apple Support for assistance. If your Mac was introduced before June 2013, it uses Apple Hardware Test instead. To run the Mac speed test, do the following: Launch the app. Click the Start Tests button. Novabench will start running different tests. Wait 1-2 minutes for the tests to run. Don’t use your computer during the tests. Get the results of each test along with the Novabench score (the higher the number you’ve got, the better).

Mi MAC mini es de los antiguos por lo que llevan AHT (Apple Hardware Test), es un herramienta de diagnostico del Hardware que venia preinstalado en los Macs. Desde Junio del 2013 Apple preinstala en los equipos un software similar pero al cual ha denominado como Apple Diagnosis. Macs are no different, which is why Apple has an easy-to-use diagnostic utility built into each computer called Apple Hardware Test (AHT) manufactured before June, 2013.
System cleanup in one click
Make your Mac fast and secure with CleanMyMac X.
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:
- 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.
- Select Apple Menu > Restart
- Press and hold the D key until you see a list of different languages on the screen
- Select a language. Apple Diagnostics starts automatically.
- 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 2020.
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. Each code stands for a particular error and helps you quickly figure out the next steps. Usually, an error description will suggest possible solutions. 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:
- Repeat the process by hitting Run the test again
- To get more information on support and service options, click on Get started:
- The macOS X recovery will start
- Send your serial number and reference codes to Apple by clicking Agree to send
- Follow the on-screen instructions.
- Restart your Mac
- Hit the Shut Down button.
Because well, sometimes a small mistake might hamper it all. Maybe the first time you tried to run Apple Diagnostics, your power adapter wasn't plugged in. Connect it and try again — this will help fix the problem.
What if you can't run diagnostics
Apple Hardware Test Macos Catalina
You can face the problem when Apple Diagnostics simply doesn't work. Don't worry, it's solvable. There might be a couple of reasons why this happens:
- Some external devices are plugged in. Double-check you've disconnected everything except the keyboard, mouse, display, and speakers.
- 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.
- Firmware password might be the problem. Make sure you turn it off while performing hardware testing.
What if diagnostics found no issues
In case Apple Diagnostics identifies no hardware issues — but your Mac is still misbehaving — maybe, software is the problem.
Often, Macs are slowing down, freezing, or behaving strangely due to full storage, malware, leftovers from uninstalled apps, large and old files. The good news is you don't have to guess, or install many applications to fix each problem separately. An all-in-one tool called CleanMyMac X has all the required functions to test your Mac from a to z. It cleans up, protects, and speeds up your Mac.
Just one click to optimize your Mac — CleanMyMac X makes it fly like a rocket.
Here's how CleanMyMac X optimization works:

- Press Run.
Yay, you launched a rocket!
The most common problem that impairs system performance is the junk files that clutter your Mac. You might not even know about them. Luckily, CleanMyMac X has a solution for this, too. Resolve various errors with a great feature called System Junk:
- Hit Scan
- Once you see the results, press Review Details
You'll see the list of all items that should be cleaned or fixed. You can review the results and deselect those items you're not ready to let go. CleanMyMac X will omit them while cleaning up your Mac. Once you're ready, hit Clean.

Mac Apple Hardware Test Not Working
When building an Android app, it's important that you always test your app ona real device before releasing it to users. This page describes how to set upyour development environment and Android device for testing and debugging overan Android Debug Bridge (ADB) connection.
Note:Mac Hardware Test Online
Use the Android emulator to test your app ondifferent versions of the Android platform and different screen sizes. Alsoconsider using Firebase Test Labto run your app on a wide variety of real devices hosted in acloud-based infrastructure.Set up a device for development
Before you can start debugging on your device, there are a few things you mustdo:
- On the device, open the Settings app, select Developer options, andthen enable USB debugging.Note: If you do not see Developer options, follow the instructions toenable developer options.
- Set up your system to detect your device.
- Chrome OS: No additional configuration required.
- macOS: No additional configuration required.
- Ubuntu Linux: There are two things that need to be set up correctly:each user that wants to use adb needs to be in the plugdev group,and the system needs to have udev rules installed that cover the device.plugdev group: If you see an error message that says you're not in theplugdev group, you'll need to add yourself to the plugdev group:Note that groups only get updated on login, so you'll need to log out forthis change to take effect. When you log back in, you can use
id
tocheck that you're now in the plugdev group.udev rules: Theandroid-sdk-platform-tools-common
package containsa community-maintained default set of udev rules for Android devices. Toinstall: - Windows: Install a USB driver for ADB. For an installation guide andlinks to OEM drivers, see the Install OEM USB driversdocument.
Connect to your device
When you are set up and plugged in over USB, you can click Run in Android Studio to build and run your app on the device.
You can also use adb to issue commands,as follows:
- Verify that your device is connected by running the
adb devices
commandfrom yourandroid_sdk/platform-tools/
directory. Ifconnected, you'll see the device listed. - Issue any adb command withthe
-d
flag to target your device.
Troubleshoot device connection with the Connection Assistant
The Connection Assistant provides step-by-step instructions to help you set upand use a device over the ADB connection.
To start the assistant, choose Tools > Connection Assistant.
The Connection Assistant provides instructions, in-context controls, and a listof connected devices in a series of pages in the Assistant panel. Use theNext and Previous buttons at the bottom of the Assistant panel towork through the pages as needed:
- Connect your device over USB: The Connection Assistant begins by promptingyou to connect your device over USB, and it provides a Rescan USB devicesbutton with which you can start a new scan for connected devices.
- Enable USB debugging: The Connection Assistant then tells you how toenable USB debugging in the on-device developer options.
- Restart the ADB server: Finally, if you still don't see your device on thelist of available devices, you can use the Restart ADB server button on thelast page of the Connection Assistant. Restarting the ADB server also causesADB to scan for devices again. If you still don't see your device on the listof available devices, try the troubleshooting steps in the next section of thispage.
Resolve USB connection issues
If the Connection Assistant is not detecting your device over USB, you can trythe following troubleshooting steps to resolve the issue:
Check that Android Studio can connect to the Android Emulator
To check if the issue is being caused by a connection problem between AndroidStudio and the Android Emulator, follow these steps:
- Open the AVD Manager.
- Create a new AVD if you don't alreadyhave one.
- Run the emulator using your AVD.
- Do one of the following:
- If Android Studio can't connect to the emulator, download the latest SDK Platform Toolsand then try again.
- If the emulator starts successfully, check the USB cable.
Check the USB cable
To check if the issue is being caused by a faulty USB cable, follow the steps inthis section.
If you have another USB cable:
- Connect the device using the secondary cable.
- Check if the Connection Assistant can now detect the device.
- If the device is not detected, try the primary cable again.
- If the device still isn't detected, assume that the problem is with thedevice and check if the device is set up for development.
If you don't have another USB cable but you do have another Android device:
- Connect the secondary device to your computer.
- If the Connection Assistant can detect the secondary device, assume that theproblem is with the primary device andcheck if the device is set up for development.If the secondary device is not detected, the problem might be with the USBcable.
Check if the device is set up for development
To check if the issue is being caused by settings on the device, follow thesesteps:
- Follow the steps in the Set up a device for developmentsection.
- If this does not resolve the problem, contact the device OEM'scustomer support for help. Tell the customer support representative that thedevice won't connect to Android Studio using ADB.
RSA security key
When you connect a device running Android 4.2.2 (API level 17) or higher to yourcomputer, the system shows a dialog asking whether to accept an RSA key thatallows debugging through this computer. This security mechanism protects userdevices because it ensures that USB debugging and other adb commands cannot beexecuted unless you're able to unlock the device and acknowledge the dialog.
