Definition: Mac Pro

Apple's professional workstation, which was introduced in 2006. Other Apple products also use the Pro designation (see MacBook, iMac and iPad). The current, second-generation Mac Pro, which debuted in 2013, is a dramatic departure from the first, as well as all other desktop computers. It is a cylinder with six to 16 Intel Xeon CPU cores, supporting up to 64GB of RAM, 1TB of solid state storage (SSD) and three 5K displays. Designed for video editing and rendering, it features dual AMD FirePro graphics processors (GPUs) with up to 6GB of dedicated memory. See Macintosh models, Mactel and Power Mac.

Mac Pro Cylinder
The second-generation 10" Mac Pro cylinder was a dramatic departure in design. Using a thermal core and single fan, air is drawn out through the top around the gargoyle (a personal addition). All peripheral expansion is accomplished via USB 3.0 and Thunderbolt ports; for example, RAID storage arrays connected via Thunderbolt.

First-Generation Mac Pro
With up to 12 cores, the original Mac Pro was in a tower case powered by Intel x86 chips rather than PowerPC, Apple's previous CPU platform. It supported 64GB of RAM and had plenty of room for internal storage. It is shown here with Apple's coveted 30" monitor, later discontinued.

Coveted in the Past
Once top-drawer computers, used first-generation Mac Pros are retrofitted for their sturdy cases like these units at Dtown Tech in Doylestown, Pennsylvania.

Third-Generation Pro
Expected in the fall of 2019, the third-generation model reverts to the traditional tower case but with a unique flair. The 3G Pro can be configured as a powerhouse with 28 CPU cores, 1.5TB of RAM, four GPUs and 4TB of SSD storage. (Image courtesy of Apple, Inc.)
