The reason of this development owes to the advanced security features of Apple's T2 chip that might become vulnerable after a third-party fix. On iMac Pros, it will kick in if the Logic Board or flash storage are replaced. If you were to change your MacBook Pro's display, logic board, keyboard, trackpad and the Touch ID, the device will be locked.
The software lock will engage in different circumstances for the 2018 MacBook Pro and the iMac Pro though. A new feature is that at the final stage of fixing the gadget he needs to run a proprietary diagnostic tools Apple Service Toolkit 2, available only in the service centers.
Along with the 2018 MacBook Pro, the T2 security chip is included in Apple's iMac Pro. Should Apple be more open about the repairability of a product after the purchase or the company should have strict laws when it comes to third-party repairs?
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".
Another report from Motherboard states that the Apple diagnostic suite only functions when it is connected to Apple's cloud-based Global Service Exchange server which further requires a valid Apple ID for access. "Failure to perform this step will result in an inoperative system and an incomplete fix", the document explains.
Apple is now fighting "Right to repair" legislation in the USA which would require the company to make fix parts, tools, fix guides, and diagnostic software public.
This is according to a document that was distributed to Apple Authorized Service Providers last month, and obtained by MacRumors and Motherboard yesterday.
This software ensures that if a device undergoes key part repairs from an unauthorized service provider, it will result in an "inoperative system and an incomplete fix".
While many will point to this as Apple's way of getting more money out of its users, it's possible this is all being done in the name of security in order to preserve the data stored in that T2 chip.
Apple introduced a new proprietary diagnostic software for their computers.
