Apple announced the original Mac Pro 20 years ago today, with the anniversary landing five months after the company discontinued the machine for good. On August 7, 2006, Apple unveiled the first Mac Pro, powered by two dual-core 64-bit Xeon processors that Apple said made it up to twice as fast as the Power Mac G5 it replaced. The Mac Pro remained as Apple's professional flagship for almost the next two decades since its launch. Apple discontinued the Mac Pro on March 26, 2026, pulling it from its website. With the Mac Pro gone, the Mac Studio is now Apple's most powerful desktop, though it lacks the tower's internal PCIe expansion slots.
