Apple has announced that it would not be advised to take your new MacBook Pros and iMac Pros to a third-party repairman. It could only mess with your system and make issues worse!
Apple is reportedly using propriety software diagnostic tools to repair MacBook Pros and iMac Pros. So, a third-party repair may not be able to fix issues pertaining to display assembly, trackpad, the keyboard, the logic board, and the Touch ID board. Further, if a third party repair is tried on the iMac Pros then an automatic bolt would lock the system. The system will not be able in a usable condition unless the Apple Service Toolkit 2 is used by Apple’s Authorized Service Provider program.
Apple’s proprietary chip T2 has taken over a lot of responsibilities in the iMac Pros and the new MacBook Pros. They are in charge of storing secure enclave data and managing disc encryption in these systems. So, it seems reasonable that the company is taking steps that would ensure the security of its new iMac pros and MacBook Pros.
The company has reportedly sent a document to its Authorized Service Providers informing them of the lockdown feature in the new iMac Pros and the 2018 MacBook Pros.
