An anonymous reader shares a report from The Verge about Apple's new security-focused T2 chip found in the newest Mac computers. The introduction of the chip "has renewed concerns that Apple is trying to further lock down its devices from third-party repair services," The Verge reports. From the report: The T2 is "a guillotine that [Apple is] holding over" product owners, iFixit CEO Kyle Wiens told The Verge over email. That's because it's the key to locking down Mac products by only allowing select replacement parts into the machine when they've come from an authorized source -- a process that the T2 chip now checks for during post-repair reboot. "It's very possible the goal is to exert more control over who can perform repairs by limiting access to parts," Wiens said. "This could be an attempt to grab more market share from the independent repair providers. Or it could be a threat to keep their authorized network in line. We just don't know." Apple confirmed to The Verge that this is the case for repairs involving certain components on newer Macs, like the logic board and Touch ID sensor, which is the first time the company has publicly acknowledged the tool's use. But Apple could not provide a list of repairs that required this or what devices were affected. It also couldn't say whether it began this protocol with the iMac Pro's introduction last year or if it's a new policy instituted recently.
First revealed last month by MacRumors and Motherboard, both of which got their hands on an internal Apple document, the T2 chip could render a computer inoperable if, say, the logic board is replaced, unless the chip recognizes a special piece of diagnostic software has been run. That means if you wanted to repair certain key parts of your MacBook, iMac, or Mac mini, you would need to go to an official Apple Store or a repair shop that's part of the company's Authorized Service Provider (ASP) network. If you want to repair or rebuild portions of those devices on your own, you simply can't -- at least, according to this document. The parts affected, according to the document, are the display assembly, logic board, top case, and Touch ID board for the MacBook Pro, and the logic board and flash storage on the iMac Pro. It is also likely that logic board repairs on the new MacBook Air and Mac mini are affected, as well as the Mac mini's flash storage. Yet, the document, which is believed to have been distributed earlier this year, does not mention those products because they were unannounced at the time. Regardless, to replace those parts, a technician would need to run what's known as the AST 2 System Configuration suite, which Apple only distributes to Apple Stores and certified ASPs. So DIY shops and those out of the Apple network would be out of luck.
