Apple T2

The Apple T2 chip is a SoC from Apple first released in the iMac Pro 2017. It is a 64-bit ARMv8 chip (a variant of the A10, or T8010), and runs a separate operating system called bridgeOS 2.0, which is a watchOS derivative. It provides a secure enclave for encrypted keys, gives users the ability to lock down the computer's boot process, handles system functions like the camera and audio control, and handles on-the-fly encryption and decryption for the solid-state drive. T2 also delivers "enhanced imaging processing" for the iMac Pro's FaceTime HD camera. On July 12, 2018, Apple released an updated MacBook Pro that includes the T2 chip, which among other things enables the "Hey Siri" feature. On November 7, 2018, Apple released an updated Mac mini and MacBook Air with the T2 chip.
