Overview

The Apple iMac 21.5-inch with Retina 4K Display (model MNDY2LL/A) packs a complete computing experience into its signature slim aluminum enclosure. At the heart of the machine is a 3.0GHz quad-core seventh-generation Intel Core i5 processor paired with 8GB of RAM and a 256GB SSD, providing snappy boot times and responsive application performance for everyday tasks like web browsing, office productivity, photo editing, and media consumption. The Radeon Pro 555 discrete graphics card adds enough capability for casual creative work and smooth 4K video playback.

The standout feature remains the 21.5-inch Retina 4K display running at 4096x2304 resolution, which renders text, images, and video with impressive clarity and color accuracy. Connectivity includes 802.11ac Wi-Fi, Bluetooth 4.2, and a built-in FaceTime HD camera for video calls. As a renewed unit, this iMac offers the same hardware experience at a reduced price point compared to buying new, making it an appealing option for home offices, students, or anyone who values a clutter-free desk and a beautiful display without the cost of a current-generation model.
