At the beginning of last month, we talked about an Apple document which stated that the T2 security chip, present in iMac Pro and in the new MacBooks Pro, Air and Mini macs, could cause these machines to stop working if Apple’s verification software doesn’t run after certain repairs. However, the company had not confirmed this information – until now.
The Cupertino giant confirmed for the The Verge that repairs involving certain components, such as the logic board and the Touch ID sensor, are verified after replacing those parts. The T2 chip performs such an analysis during the post-repair Mac reboot and verifies whether the replaced components come from an authorized source.
The software, which makes up the Apple Service ToolKit, works in conjunction with the security chip and includes tools, such as the “Mac Origin Inspector”, that examine a variety of computer components. As we reported, this kit is restricted to Apple Stores and Apple Authorized Service Centers, which have access to the network Global Service Exchange (GSX) from Apple.
The company did not, however, report all components «affected» by this policy, nor did it confirm whether the verification is new or whether it has occurred since the iMac Pro was introduced last year. However, according to the document released last month, the parts involved in this verification are, in addition to the logic board and the Touch ID sensor, the top case and flash storage on the iMac Pro – according to The Verge, Apple confirmed that replacing the Macs’ screen does not require running the verification software.
It is also likely that repairs to the new MacBook Air and Mac mini will be affected, however the released document does not mention these machines – not least because they were not announced at the time. Despite this, we commented that iFixit performed some tests and replaced certain components, such as the logic board of the new MacBook Pro, and did not see any problems after the repair – perhaps because these parts were properly validated by Apple.
As always, this discussion touches on the consumer’s freedom to choose wherever he wants to repair his device, the infamous right to repair. Last May, the company lost a lawsuit involving a Norwegian repair company that uses alternative parts for repairing iPhones, but the same may apply for repairs on Macs.
