Apple is reportedly going to introduce a 21.5-inch iMac next week. The smaller iMac with Retina display will be announced on Tuesday and it could be released by October 13, according to a 9to5Mac report. In September, a piece of code in OS X El Capitan was found that essentially confirmed the existence of an upcoming 21.5-inch 4K iMac.

Outside of the smaller iMac, the only Apple computers that don't have a Retina display are the MacBook Air and old unibody MacBook Pro.

A new graphics card and Broadwell processors will also be used in this new iMac.
