The T2 processor isn't doing the heavy lifting in the iMac Pro - that's the Intel Xeon processor with between 8 and 14 processor cores. The T2 is the brain behind that brain, running the subsystems of the iMac Pro from a single piece of Apple-built silicon. The result is a simplified internal design that doesn’t require multiple components from multiple manufacturers.

On most Macs, there are discrete controllers for audio, system management and disk drives. But the T2 handles all these taks. The T2 is responsible for controlling the iMac Pro's stereo speakers, internal microphones, and dual cooling fans, all by itself.

It's a fascinating chip that certainly puts Apple ahead of its competitors, but at the same time, it's going to make installing non-approved operating systems on Macs ever harder. Sure, they're allowing it for now, but for how long?
