~ the last words ~

Apple announced the Mac Pro at WWDC on 7 August 2006, and it was the last Mac in the lineup to make the jump from PowerPC to Intel. The case was the Power Mac G5's, near enough: same aluminum, same external dimensions, two pounds lighter, and with the hot G5 processor gone there was room inside for four hard drive bays and two optical drives. Every drive slid in on a sled with no cables to connect. It was a workstation that assumed you were going to open it.

That assumption held for six years and then stopped. The June 2012 update was so thin, still on old Westmere Xeons with no Thunderbolt and no USB 3, that Apple took the "new" badge off it in its own store. Tim Cook told a customer by email that something better was coming. What came was the 2013 cylinder, previewed at WWDC that June with Phil Schiller saying "Can't innovate anymore, my ass" from the stage, and released on 19 December 2013 at one-eighth the volume of the tower it replaced.

The cylinder was beautiful and it was a dead end. Two fixed AMD GPUs around a single thermal core, nothing meaningful to upgrade, and no thermal headroom to put a faster part in later. It received no significant update for six years, which for a machine sold to people whose work is bounded by compute is not neglect so much as abandonment. Apple confirmed in April 2018 that a replacement was coming, and the tower came back on 3 June 2019 with eight PCIe slots, a lattice front and memory to 1.5 TB.

I have never owned one. The machines I have actually worked on follow a different logic anyway: you buy the box for the card you are going to put in it, and the box is worth what it will still accept in three years. By that measure the Mac Pro spent its last decade going backwards, and the version of it I would have wanted was the one Apple stopped making in 2013.

~ the cylinder years ~

There is a detail in the 2013 machine that says everything about how it was designed. Apple published mandatory tightening torque values for nearly every screw inside it, with the ones holding the GPUs and the CPU riser to the thermal core being the critical set, and warned that getting them wrong could damage the machine. Almost everything in there is technically replaceable. Almost nothing in there is replaceable by you.

It was assembled in Austin by Flextronics, on a highly automated line, as an answer to political criticism of Apple's reliance on overseas manufacturing. One Apple engineer later called the move a fiasco, because building something that intricate in the United States meant flying Foxconn engineers over from China to make the line work. The machine that was supposed to prove American assembly was possible needed Chinese engineers to assemble it.

~ the comeback ~

The 2019 Mac Pro was a real apology in hardware. Three impeller fans and a thermal design meant to hold peak clocks without throttling, twelve DIMM slots, MPX modules for graphics that drew cooling from the chassis instead of carrying their own fans, and the first Mac since the Power Macintosh 9600 in 1997 with six or more expansion slots. You could get it on wheels or in a rack. It arrived alongside the Pro Display XDR, and the $999 stand for that display became a running joke that outlived both products.

It was also the last one that made sense. When Apple silicon arrived, the M2 Ultra Mac Pro of June 2023 kept the 2019 chassis and six PCIe slots but could not use a discrete GPU over any of them, and the memory was on the package rather than in sockets. Mark Gurman reported that Apple built a chip pairing two M2 Ultras for this machine and canceled it on cost. The Verge measured the result against a Mac Studio with the same silicon and found a seventy-five percent price premium buying you slots and better cooling.

~ what got buried with it ~

Apple showed new Mac Studio models with M4 Max and M3 Ultra chips on 5 March 2025 and said nothing about the Mac Pro. By November the reporting was that the M4 Ultra had been canceled and the product largely written off internally. The confirmation came on 26 March 2026: discontinued, no replacement planned, the Mac Studio now the top of the desktop line.

Marco Arment made the point that Apple shrank the market for this machine itself, by raising the price and narrowing who it served, in a decade when demand for big desktops was already falling. He and John Siracusa landed on the same conclusion, that the last good Mac Pros were the Intel ones. What actually ended is smaller and more specific than a product line. It is the last Mac you were expected to unscrew.
