In a document distributed to Apple's Authorized Service providers and obtained by Macrumours or Motherboard, the firm has made it clear that if the MacBook and iMac devices are not repaired using the native diagnostic tool, it will result in "inoperative system and an incomplete fix". A document obtained by Motherboard reveals that Apple's proprietary diagnostic software will render the machine inoperative unless a proper system configuration software is run after parts of the system are replaced.
The diagnostics toolkit that performs these tests are only available as Apple Service Toolkits, and are for internal use with the Apple Stores and authorised service providers.
Motherboard reports that the Apple diagnostic suite only functions when connected to Apple's cloud-based Global Service Exchange (GSX) server and requires a valid Apple login to access. Eliminating independent repairs from its current-gen lineup, and possibly all future models, will enable Apple to control the fix process for its desktop and laptop computers.
It's worth pointing out that replacing the RAM or SSD storage on either the 2018 MacBook Pro or iMac Pro will require removing the logic board from the machine, entirely, making it even more hard to upgrade these components, successfully, after the fact. For the iMac Pro, the lock is limited to the logic board and flash storage changes.
This move by Apple seems to have been taken to prevent fraudulent repairs of its range of laptops while it also hints in creating a central command for its products.
All of this essentially means if your Mac is broken, unless you take it to Apple or an Apple-authorized service center, an independent fix by yourself or a local small business will make your device unusable. "Apple's new guidelines for repairs make matters even worse for ordinary users who don't have a lot of money to get authentic repairs". Otherwise, the device will be rendered an "an inoperative system and an incomplete fix".
Apple has yet to respond to requests for comment about the matter.
