IMac Pro and 2018 MacBook Pro systems must go through Apple Diagnostics to work after some repairs [Updated]

For the 2018 MacBook Pro, this requirement applies to repairs that require display, logic board, Touch ID, and upper case, including keyboard, battery, touchpad, and speakers. according to the document. For the iMac Pro, this requirement applies only to logic board and flash storage repairs.

If any of these parts are repaired in an iMac Pro or a 2018 MacBook Pro and that Apple's diagnostics are not executed, this would result in an inoperative system and an incomplete repair, in accordance with Apple's directive at the same time. intention of the service providers.

The Apple Diagnostics Suite is limited to internal use by Apple Stores and Apple Authorized Service Providers, as part of the so-called Apple Service Toolkit. As a result, independent repair shops that do not have Apple certification may not be able to repair parts of the iMac Pro and the 2018 MacBook Pro.

In addition, when the iMac Pro and the 2018 MacBook Pro are finally classified as vintage products, which means that they are no longer eligible for Apple's hardware service, repairs through other channels may not be possible.

MacRumors has contacted Apple for comments.

This requirement results from the T2 chip, which incorporates several previously separate components, including the system management controller, the image signal processor, the audio controller, and the SSD controller. It also features a Secure Enclave coprocessor for secure boot, encrypted storage, and Touch ID authentication.

Update: Despite the specific wording of the Apple document, according to which the failure to run Apple diagnostics after replacing some parts on T2-equipped Macs "will result in an inoperative system", experts in iFixit repair exchanged the display and logic board on a 2018 Pro MacBook, and it remained operational without going through any diagnostics.

iFixit is not an Apple Authorized Service Provider. So it seems that independent repair shops should be able to repair without problem the iMac Pro and the 2018 MacBook Pro. It's unclear why the Apple document suggests the opposite.
