Five years ago today, Apple launched the iMac Pro, a high-end all-in-one desktop machine.

In April of last year, Apple apologized for its approach to the Mac in recent years and said it was working on a new Mac Pro with a modular design, a new iMac and a high-end external display. After years of rumors, Apple unveiled the iMac Pro. The iMac Pro was launched four years after the launch of the "trashcan" Mac Pro, but two years before the current Mac Pro.

The iMac Pro was said to be the most powerful Mac ever made. There was a starting price of $4,999 for the 8-, 10-, 14-, or 18-core Intel Xeon processor options. It was the first Mac to have a custom T2 chip, as well as the first desktop Mac to be available in space gray. The processor, memory, and storage were not soldered in and could be removed if the display was disassembled.

The iMac Pro was discontinued by Apple. The final update for the iMac and the first Apple Silicon Macs were released by that time. The iMac Pro is no longer in Apple's product lineup.

There was a spike in interest in an iMac Pro with a larger display after the launch of the iMac with a 24 inch screen. There is a rumor that Apple is working on a larger-screened iMac aimed at the professional market. There are reports that Apple doesn't plan to release a new iMac.
