Apple can lock MacBook Pro and iMac Pro after repair by third-party

Posted 05 October 2018 16:08 CET by Jan Willem Aldershoff

Apple uses new software to validate MacBook Pro and iMac Pro repairs. For specific repairs, the devices need to pass Apple diagnostics. If the software is not used, or the device doesn’t pass the diagnostics process, the result will be an inoperative system.

The information comes from an internal Apple document that was obtained the website MacRumors.

Apple is reportedly taking the measure due to security features of the new Apple T2-chip in the iMac Pro and MacBook Pro from this year. The T2-chip integrates  integrates several previously separate components, including the system management controller, image signal processor, audio controller, and SSD controller. It also takes care of encryption of data, secure boot and fingerprint authentication.

Apple’s diagnosis software is not required for repair of all components. For the MacBook Pro the software check is only required when display, mainboard, fingerprint scanner and battery are replaced. On the iMac Pro the Apple diagnose software is only required for repairs on the mainboard and NAND flash memory.

Only Apple Stores and Apple authorized repair shops are able to perform the diagnosis with Apple’s special software. This has made it impossible for other repair shops to repair both Apple models.
