2018/10/05: Last year, Apple outraged independent technicians when they updated the Iphone design to prevent third party repair, adding a "feature" that allowed handsets to detect when their screens had been swapped (even when they'd been swapped for an original, Apple-manufactured screen) and refuse to function until they got an official Apple unlock code.
Now, this system has come to the MacBook Pros and Imac Pros, thanks to the "T2 security chip" which will render systems nonfunctional after replacing the keyboard, screen, case, or other components, until the a proprietary Apple "configuration tool" is used to unlock the system.
Apple does not tell its customers that the computers it sells are designed to punish them for opting to get their property repaired by independent technicians; the details of the T2 came from a leaked service manual.
“There’s two possible explanations: This is a continued campaign of obsolescence and they want to control the ecosystem and bring all repair into the network they control,” Kyle Wiens, the CEO of iFixit, told me on the phone. “Another is security, but I don’t see a security model that doesn’t trust the owner of the device making much sense.”
