2018 MacBook Pro and iMac Pro No Longer Repairable in Independent Shops
iMac Pro and 2018 MacBook Pro devices repaired by third-parties will be automatically locked if the proprietary Apple Service Toolkit 2 diagnostics software is not run after replacing critical components according to a report by Motherboard.
Moreover, in the case of the iMac Pro, the Service Toolkit 2 diagnostics have to be run after replacing the computer’s logic board or flash storage.
If you repair your 2018 MacBook Pro, you have to make sure that you run Apple Service Toolkit 2 after switching the logic board, display assembly, or the top case (the touchpad, keyboard, and internal housing).
Both Mac models mentioned above feature the new Apple T2 chip responsible for managing multiple system components, from the system management controller and audio controller to the image signal processor and the SSD controller.
