Apple's new Mac introduces the T2 chip, making third-party repair completely impossible

The disassembly of Apple hardware has repeatedly shown that the repair of these devices is very difficult. Apple doesn't want to let you repair its equipment yourself, so why should it be convenient for repairs? However, with the introduction of the T2 chip, Apple will completely prevent anyone other than an authorized service provider from repairing the product.

The T2 is a 64-bit ARMv8 chip running an operating system called BridgeOS. Apple originally added the chip to the iMac Pro in December 2017 for a variety of security purposes, including protecting boot processes, protecting encryption keys, and handling system-level features such as access to cameras. The T2 chip has also recently been added to the 2018 MacBook Pro launched in July.

According to MacRumors, Apple's internal documentation shows that in order to complete some repairs to the T2 chip's iMac Pro and MacBook Pro, proprietary diagnostic software is required. If you do not use the software, the system will not work.

For MacBook Pro, this requirement applies to displays, logic boards, Touch IDs, and any peripherals, including keyboards, trackpads, speakers, and batteries. For iMac Pro, you also need to use the software if you want to repair the logic board and flash.

As you might guess, Apple only provides diagnostic software to its own stores and authorized service providers. Therefore, if you use an Apple device with a T2 chip installed, you will not be able to repair it yourself or find a repair shop that is not certified by Apple. To make matters worse, once Apple decides to stop technical support for such devices in the future, these devices will be completely unrepairable.

If you feel that the purchase cost of the iMac Pro and MacBook Pro is not high enough, the requirement for proprietary software during maintenance will impose a strict limit on the life of the device. Apple's approach is probably not limited to these two products, and we may see more, if not all, Mac computers with T2 chips installed in the future.

Prohibition of self-repair will eventually result in higher prices and a mandatory retirement. The best way is to support initiatives and bills on product repair rights, such as the “California Maintenance Rights Act”. You can also choose not to buy Apple products, but there may not be too many people willing to do so.
