Apple’s T2 chipset is designed to restrict third-party repairs on latest Macs

“To repair the newer Macs, a special configuration software suite is required to finish the process

Apple launched its latest MacBook Air 2018 along with the iMac Pro last month. The latest MacBook brings a number of improvements over its predecessor like the much-wanted Retina display, slimmer and more compact design, louder speaker, better speaker and Touch ID. To secure the data being used by Touch ID, Apple has equipped the new laptop with the T2 Security Chip. However, it turns out that the T2 chip is designed to do much more than just securing the data.

iFixit CEO Kyle Wiens told The Verge that going forward, Mac products will only boot when select replacement parts in the device have come from an authorised source. This will be checked by the proprietary diagnostic tool using the T2 chip during the post-repair reboot. The brand itself has confirmed that repairs of several components on newer Macs have to be done by the authorised service centres or Apple Stores. These components include 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. However, the brand has assured that a majority of repairs won’t be affected by this.


In order to repair or replace these components, the technician is required to run the AST 2 System Configuration suite. Notably, the suite is distributed by Apple only to Apple Stores and certified ASPs. This means that any repairs and replacements from third-party repair shops are going to render your latest Mac device useless. There are several logical reason behind this move by Apple, like making sure that the data harvesting replacement parts are not installed or to make sure original parts are used to maintain the quality.

Whatever the reason might be, factoring in the cost of maintenance and replacement while making the decision to buy the newest Mac will do you good.
