Apple is reportedly preparing to introduce a new high-resolution iMac into its lineup. The company is said to readying a new model of its 21.5-inch all-in-one desktop with a 4K display. The new model could arrive by the end of October, coinciding with the release of OS X El Capitan.

From 9to5Mac:

Apple is indeed planning to release a new version of its 21.5-inch iMac with a 4K display this fall, according to reliable sources. The current plan is to announce the refreshed version of the smaller iMac by the end of October alongside OS X El Capitan and begin shipping the product by the beginning of November.

To see a 4K version of Apple's smaller iMac seems like a natural step from last year's introduction of the 27-inch iMac with 5K Retina display. Additionally, if last year is any indication, expect the non-Retina versions of the 21.5-inch iMac to stick around at their lower price point, as a 4K version would likely have a noticeably higher starting price.
