Apple will launch the iMac Pro on 14 December, almost six months after the ultra-powerful computer was announced.

The iMac Pro will join the Mac range rather than replace the Mac Pro model. The Mac Pro is expected to be upgraded in 2018.

Interested users will be treated to high-end specs including 128GB of RAM, an 18-core Xeon processor and up to 4TB of solid-state storage. it will also feature four USB 3 ports and four USB-C Thunderbolt ports.

But buyer beware: all that hardware is not going to come cheap. Apple will launch the iMac Pro at a starting price of $4,999. A UK price has not yet been confirmed, however given the similarities in pricing between the US and UK models of the Mac Pro (both 2,999), expect the cost to be similar.

It is important to remember the starting price provides the base specifications which includes an 8-core Xeon processor, 32GB of RAM and a 1TB solid-state drive. While still impressive, pricing has not yet been revealed on the maxed-out model with the specifications mentioned above.

One other feature of the iMac Pro is the colour. It will be the first desktop model to ship in Apple's Space Gray. The keyboard, mouse and trackpad will all come in Space Gray.

Apple's Mac Pro - which is often mocked for looking like a rubbish bin - was released in 2013 with a 12-core Xeon processor, 256GB of storage and 64GB of RAM. But because of its design, the computer was not user-upgradebale, much to the chagrin of creatives. Apple has promised a "radical revamp" of the Mac Pro in 2018.
