The Apple TV has really packed on some pounds since its last iteration.

It seems to have lost a port in the process—the optical audio out has gone MIA.

Meanwhile, the micro-USB port has morphed into a USB-C port. It doesn't bring anything new for end users, though—it's still for diagnostic and service functions only.

Our teardown engineers go to work on the Apple TV and quickly find access through the bottom of the device—similar to the 3rd generation Apple TV.

Only a few plastic clips stand in the way here, with no adhesive or screws in sight.
