For those who want to repair their Apple iPhone or Mac by themselves, Apple is now offering an online diagnostics tool for Self Service Repair. This tool is great for helping identify specific hardware or software issues for your device. Let’s take a look.

How Do I Use Apple Diagnostics for Self Service Repair?

Apple Diagnostics for Self Service Repair is a means to help identify issues with your Apple device. This online tool is different from the Apple Diagnostics you can typically run on a Mac. It not only expands to iPhone and more specific hardware issues on Mac, but it’s the same diagnostic tools used at an Authorized Apple Service Provider.

Once you are able to determine what is wrong with your device through the use of these tools, you can then move forward with the Apple Self Repair process.

1. Use Apple Service Diagnostics for Self Service Repair on iPhone

Note icon NOTE
This feature is only available for iPhone 12 models or later that are capable of powering on.

Before beginning, ensure the following:

  1. Make sure your iPhone is up to date via Settings > General > Software Update. If the device you are testing is running a beta, you will need to switch to a public release of iOS 17 or later.
  2. You must identify the model of your iPhone.
  3. You will need a secondary device for this task. This includes either an iPhone or iPad running iOS 13 or later, a Mac running macOS Catalina 10.15 or later, or a PC with Chrome 55, Firefox 59, or Microsoft Edge 12 or later. For Mac, iPad, and iPhone, you will need the Safari browser.
  4. A proper Wi-Fi connection will be necessary for both devices. The secondary device may use cellular, but the iPhone undergoing diagnostics must use Wi-Fi.

Time needed: 30 minutes

Follow the steps below to diagnose your iPhone using Apple’s online tools:

  1. From the secondary device, visit this official Apple Diagnostics website.

  2. Click Continue on the website and select iPhone.

2. Use Apple Service Diagnostics for Self Service Repair on Mac

Note icon NOTE
Intel-based Macs are not supported for this tool. You can double-check via Apple > About This Mac. The Mac you are diagnosing must also be capable of turning on.

Before beginning, ensure the following:

  1. You cannot run a beta version of macOS. You must be running macOS Sonoma 14.1 or later on the Mac you are testing.
  2. You will need a secondary device. Just like the iPhone diagnostics, Mac also requires a secondary device. Check above for the full specifics.
  3. You will need an internet connection on the Mac you are diagnosing and the secondary device. The Mac can use a wired or wireless connection. The secondary device may use a cellular, wireless, or wired connection.
  4. You will need to know the model of your Mac.

Performing Your Test

  1. First, prepare the Mac you are testing. Shut down the Mac via Apple > Shut Down and disconnect all external devices except for your mouse, keyboard, and display. Ensure the power connector is attached to your device.
  2. On your secondary device, visit this official Apple Diagnostics website. Tap Continue.

Does Apple Allow Self Repair?

Yes. Apple does allow self repair. In fact, Apple provides repair manuals, parts and tools to help you service your devices on your own. While this can be more of a challenge than visiting an Authorized Apple Service Provider, many can find repairing their own devices to be rewarding. Keep in mind that Apple Diagnostics is just the first step toward discovering what is wrong with your device.

While this may be the first step toward repairing your Mac or iPhone on your own, remember that Apple Support is also available.
