Apple iMac is now rumoured to have 4K optionReuters

Apple is rumoured to be in plans to launch the anticipated 4K 21.5in iMac soon. The new iMac would be available as the successor to 2014's iMac models.

According to a report by 9to5Mac, citing some "reliable sources", the new 21.5in iMac with 4K Retina display will be available in initial batches as soon as on Tuesday (13 October) and will go on mass sales by November.

The site claims that the new 4K iMac physically looks "like the current non-4K version", though there is an all-new Retina display with 4,096 x 2,304 pixels resolution to deliver an enhanced experience. The new iMac is also said to come with "much faster" graphics card options and is expected to come preloaded with the newly released OS X 10.11 EL Capitan.

Although Apple has not yet revealed any details about the rumoured 4K 21.5in iMac, the site says that the new version will come at "slightly higher price points" compared to 2014's non-4K variants. The Cupertino giant is also reported to be working on a new Magic Mouse 2 with Force Touch integration and a new Bluetooth keyboard, both of which are expected to be announced sometime in the coming future.

In October 2014, Apple brought the 5K iMac that features a 27-inch Retina display with seven times more pixel count than any standard HDTV screen. This was originally launched for £1,999 but the company reduced the price to £1,599.
