I enjoyed Jason Snell’s explanation of the new T2 chip in the iMac Pro. The T2 increases security and takes over for a lot of tasks traditionally covered by a suite of separate controllers. I agree with Jason that we should fully expect the T2 (or T3) to start showing up in future Macs. It solves too many problems not to go across the line. I also look at this as further evidence that Apple isn’t done with the Mac.
