We expect the next update to the iMac lineup sometime in early to mid-2017.
Ever since the famous Bondi Blue iMac debuted way back in 1998, Apple’s all-in-one desktop computer has been setting standards in gorgeous design and powerful performance.
These days Apple is again pushing boundaries with the iMac, blessing all of its 27-inch models with the world’s best display, which has a massive 5K (5120×2880) resolution and a wider colour gamut than previous models.
Add in a quad-core Intel Core i5 processor (configurable from 3.2GHz up to 4.0GHz), 8GB of memory, a fast and capacious Fusion Drive, and a powerful AMD Radeon R9 graphics processor – and the large iMac is the desktop system to own.
The lineup as of 2016 is limited to just six models (excluding a few extreme custom options. Your choices are either the 21.5-inch or 27-inch display, and the Retina display is the clear choice (now boosted with a P3 wide colour gamut display which represents red, green and blue in a more real world way).
Retina on the 21.5-inch model is at 4K resolution and you get the stunning 5K on the 27-inch. If you really want an iMac but can’t meet the entry-level Retina price tag for the 4K model, you can still buy non-Retina for £1,049 as opposed to £1,449.

In 2015, Apple introduced the first 21.5-inch iMac with a Retina 4K (4096×2304) display. Both Retina 21.5-inch models have a quad-core processor, either 3.1GHz or 3.3GHz varieties, starting at 8GB RAM with an option of 16GB for an extra £180.
