First introduced on the MacBook Pro, Apple's T1 co-processor runs the Touch ID sensor, operates as a secure enclave for the processing and encryption of fingerprints, and acts as a gatekeeper to the microphone and FaceTime camera.
The new iMac Pro has a T2 co-processor which is a secure enclave for encrypted keys, handles system functions like the camera and audio control, manages the SSD, lets users lock down the boot process, and delivers 'enhanced imaging processing' for the FaceTime camera.[W]
Bloomberg says that Apple is working on at least three more Macs that will use its own co-processors.
So far, only two Mac lines include custom Apple processors: the MacBook Pro with Touch Bar and the iMac Pro. Apple is working on at least three updated Mac models with custom co-processors for release as soon as this year, including updated laptops and a new desktop, according to a person familiar with the plan.
Some industry watchers believe it's just a matter of time before Apple begins designing the entire CPU and becomes a rival for Intel.
