Apple confirms its T2 chip will block some third-party repairs

Lisa Gade reviews the long overdue refresh of Apple's most popular laptop, the MacBook Air. Apple has now confirmed that it blocks certain third-party repairs on these newer Mac devices with the T2 Security Chip, forcing the user to get them repaired from an Apple Store or an Apple Authorised Service Provider. Apple hasn't even verified if this is the case with just the 2018 Macs that feature the T2 chip, or if Macs from past year are also affected, according to the report.

According to the leaked document that we spoke about earlier, components such as the display assembly, logic board, top case, and Touch ID board in case of the MacBook Pro, and the logic board and flash storage in case of the iMac Pro require T2 authentication.

These chips effectively communicate with the other hardware of the Mac and cater to the seamless experience which Apple offers on its laptops. However, critics are concerned that Apple's move will greatly impact enthusiasts and third-party fix shops thereby preventing them from offering aftermarket services to Mac owners.

The processor uses an ARM-based architecture and is created to handle some of the newer features that were introduced in last year's MacBook Pros, including the Touch Bar and Touch ID.


If this does not happen, the Mac will remain "inoperative".

Word of this new policy came out last month in an Apple document circulated among authorized service providers. 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. Also, since the T2 controls most security functions on newer Macs, the diagnostics will likely ensure that the chip's security functions are not compromised as a result of repairs to the logic board or Touch ID sensor. In fact, Apple once ended up bricking hundreds of iPhones repaired by third-party shops with Error 53 post an iOS update.

Apple's T2 security chip, which is found in all new MacBook Pro, MacBook Air, iMac Pro and Mac mini is essential for numerous features these devices offer including the "Hey Siri" and Touch ID.
