The T2 chip is capable of redesigning and integrating several controllers found in other Mac systems, which means the iMac Pro is capable of doing things other iMacs can’t. With the new chip, Apple can feature a Secure Enclave coprocessor in the iMac Pro that provides “the foundation for new encrypted storage,” and makes secure boot capabilities a reality. The data on your SSD is encrypted using dedicated AES hardware with no effect on the SSD’s performance, while keeping the Intel Xeon processor free for your compute tasks. And secure boot ensures that the lowest levels of software aren’t tampered with and that only operating system software trusted by Apple loads at startup.
