On April 20, 2021, Apple discontinued the 21.5-inch Intel iMac with 4K Retina Display following the release of a 24-inch model based on the Apple M1 processor, and discontinued the remaining non-Retina models in October 2021. The Intel-based iMac was succeeded by the iMac with Apple silicon beginning in 2021 as part of the Mac transition to Apple silicon. The iMacs released in October 2012 also featured a much thinner display, with the edge measuring just 5 mm. The October 2009 iMac model featured a unibody aluminum enclosure, a version of which can still be seen on the current model. Pre-2009 iMac models featured either a white polycarbonate enclosure or an aluminum enclosure.

It was sold alongside the Xeon-based iMac Pro from 2017 to 2021.

While sold, it was one of three desktop computers in the Macintosh lineup, serving as an all-in-one alternative to the Mac Mini, and sat below the performance range Mac Pro. The Intel-based iMac is a discontinued series of Macintosh desktop computers designed, manufactured and sold by Apple Inc.
