Apple's custom T2 chip recently made its way from the iMac Pro to the 2018 MacBook Pro, where it is responsible for a lot more than people think. AppleInsider explains everything you need to know about it.
In the wake of revelations that Apple plans to employ a special diagnostics tool that effectively blocks certain third-party MacBook Pro and iMac Pro repairs, DIY specialist iFixit evaluated the issue to find the new policy is not yet active.
In a move that essentially puts the kibosh on third-party repairs, Apple with its latest Macs has instituted a T2 security chip-related feature that disables a host machine unless specialized diagnostics software is used when replacing hardware.
Some Mac owners trying to upgrade to the latest edition of macOS are encountering errors preventing them from completing the process, according to complaints on Apple's support forums.
A number of iMac Pro and MacBook Pro owners have reported issues with macOS enduring kernel panics, with initial investigations into the problems suggesting something connected to Apple's T2 security chip is to blame — but actual service numbers don't point to a hardware problem.
Apple's new T2 chip in the iMac Pro and 2018 MacBook Pro is far more than a refinement of the family of sub-processors that launched in the 2016 MacBook Pro, with expanded responsibility encompassing FaceTime camera image quality, drive security, and total control over the boot process.
A careful disassembly of the new iMac Pro has found another Apple-made chip in addition to the new T2, though close inspection of the silicon reveals it is not the A10 Fusion coprocessor some expected would be included in the powerful all-in-one.
Though it flew largely under the radar, Apple introduced a new custom T2 chip in iMac Pro that combines a number of system controllers into a single secure package. The company detailed what, exactly, the silicon does in an update to its iMac Pro product webpage on Thursday.
Apple's iMac Pro desktop will also sport an a new custom chip dubbed the T2, serving as a secure enclave for encrypted keys, giving users the ability to lock down their Mac's boot process and also handling system functions like the camera, audio control, and managing the solid-state hard drive.
