Confirmed: T2 Chip Macs Must Be Diagnosed After Repair

At the beginning of last month, we spoke of an Apple document which stated that the T2 security chippresent in iMac Pro and in the new MacBooks Pro, Air and Mini macs, could cause these machines to stop working if Ma scan software did not run after certain repairs. However, the company had not confirmed this information so far.

The Cupertino giant confirmed for the The verge Repairs involving certain components, such as the logic board and Touch ID sensor, are verified after replacement of these parts. The T2 chip performs such an analysis during the Mac post-repair reboot and checks whether the replaced components come from an authorized source.

The software that makes up the Apple Service ToolKit, works in conjunction with the security chip and includes tools such as the "Mac Source Inspector" that examine a variety of computer components. As stated, this kit is restricted to Apple Stores and Apple Authorized Service Centers, which have network access. Global Service Exchange (GSX) from Apple.

However, the company has not reported all components "affected" by this policy, and has not confirmed whether the new check has occurred or has occurred since iMac Pro was introduced last year. However, according to the document released last month, the parts involved in this verification are, besides the logic board and the Touch ID sensor, the top case and flash storage on the iMac Pro according to The verge, Apple has confirmed that Mac screen replacement does not require verification software to run.

It is also likely that repairs to the new MacBook Air and Mac mini will be affected, however the document released does not cite these machines because they had not been announced at the time. Nevertheless, we comment that iFixit has performed some testing and replaced certain components, such as the new MacBook Pro logic board, and found no problem after repair, perhaps because these parts were properly validated by Apple.

As always, this discussion focuses on the consumer's freedom to choose where they want to fix their device, the infamous right to repair. Last May, the company lost a lawsuit involving a Norwegian repair company that uses alternative parts for iPhone repairs, but the same could be true for Mac repairs.
