It would see that Apple is firmly placing its intention on forcing consumers to use Apple for its third-party repairs, which is bad news for consumers.
These tactics aren't limited to just Apple.
Apple's fix model, with this software lock that requires an authorized Apple repairperson to run the "Apple Service Toolkit" or "Apple Service Toolkit 2" software before returning a device to functionality, is a model seen with other companies as well. Now, it looks like the argument is going to spring back up again as it has been revealed that the new T2 security chip found in the 2018 MacBook Pro and iMac Pro is preventing repairs.
This presents a serious dilemma for individuals or third-party shops who don't have the Apple diagnostics tool at their disposal.
Apple is using proprietary diagnostic software to block third parties from repairing the 2018 MacBook Pro and the new iMac Pro with the new T2 chip inside them according to a report by MacRumors. So, even if you replace an SSD or RAM on your newly bought MacBook, the laptop might become unfunctional altogether. But with the introduction of the T2 chip, Apple switched from deterring repairs to outright blocking them by anyone other than Apple authorized service providers.
And, according to documents cited in both reports, Apple, along with its licensed and registered third-party service providers, are the only ones with access to the software, meaning the likelihood of conducting a fix on these machines with an unlicensed or underground service provider is nearly certain to result in system failure, too.
As of now, 19 states in the USA have proposed legislation regarding right-to-repair rules, but none of them have passed a bill that prohibits the use of proprietary diagnostic software. The device was reported as working fine afterwards. iFixit also claims to have swapped the logic board in this machine with no issues.
