Apple's new Mac Pro is assembled in the US, as its Making Of video proves. The video tracks the the creation of a Mac Pro as the machine's cylindrical case is carved, polished, and fit around its internal components. It's mesmerizing to watch, but hard to fully appreciate in just two minutes of footage. That's where product designer Greg Koenig can help. Koenig walks through the Mac Pro's manufacturing process on Atomic Delights, explaining how an aluminum ingot is turned into Apple's new high-end computer, identifying Kuka robotic arms, bead blast cabinets, and anodizing acid baths as he goes.
