Apple has announced an expansion of its self-service repair program, allowing iPhone 15 users and owners of newer M2-powered MacBooks to repair their own devices. But perhaps more interesting is the release of “Apple Diagnostics for Self Service Repair,” which Apple says will help self-repairers “test devices for optimal part functionality and performance, as well as identify which parts may need repair.”

The web-based diagnostics tool is available now in the US, and this Apple support page offers some details on how it works. You start by putting the device you’re troubleshooting into diagnostics mode, enter its serial number into a secondary device, and then follow Apple’s instructions to troubleshoot the broken device. Available tests include checking the device’s hardware and software version and identifying issues with its display (including pixel anomalies and multi-touch problems), camera, Face ID, and audio output. 

Apple notes that these diagnostics tools are meant “for users with the knowledge and expertise to repair Apple devices” but will otherwise give them access to the same testing abilities as Apple authorized service providers and repairers signed up with Apple’s Independent Repair Provider initiative.

Alongside the release of the tool, Apple is also expanding self-service repair to more of its iPhones and Macs, including more M2-based models. When the Self Service Repair program expanded back in June, it only included the 13-inch M2 MacBook Air and MacBook Pro. Now, however, the program covers a wide range of M2-powered computers, including both the 14- and 16-inch MacBook Pro, the 15-inch MacBook Air, the Mac Mini, Mac Pro, and Mac Studio.

As well as expanding to cover more devices, the self-service repair program is also expanding to cover 24 more European countries, including Croatia, Denmark, Greece, the Netherlands, Portugal, and Switzerland. In total, Apple says the program is now available in 33 countries across 24 languages and can be used to repair 35 of its products. Apple Diagnostics for Self Service Repair is currently only available in the US and will expand to Europe next year.
