Late 2015 4K Retina all-in-one

The Apple iMac MK452LL/A is a 21.5-inch all-in-one desktop released in 2015. It integrates a 4K Retina display, an Intel Core i5 processor running at 3.1GHz, 8GB of DDR3 memory, and a 1TB hard drive. The system ships with macOS and is suited for creative professionals, students, and general productivity tasks.

Mechanical hard drive limits responsiveness

The 1TB hard drive provides generous capacity for media libraries and documents. However, rotational storage delivers slower boot times, application launches, and file transfers than solid-state alternatives. The 8GB DDR3 configuration is not user-accessible for upgrades, capping multitasking headroom for memory-intensive workflows.

Sealed aluminium chassis saves desk space

The all-in-one enclosure measures 17.7 by 20.80 by 6.90 inches and weighs 12.50lbs, eliminating a separate tower and monitor stand. Ports and connectors are located on the rear of the display, requiring rear access for cable changes. The fixed stand offers tilt adjustment only, with no height, swivel, or VESA mounting options.

Perguntas sobre este artigo

Should I choose the 8GB DDR3 model or look for a higher-capacity version?

This model ships with 8GB of DDR3 memory. The specification lists a single 8GB configuration, so there is no higher-capacity version of this exact part number to select.

What does the 3.1GHz Core i5 speed deliver in daily use?

The 3.1GHz Intel Core i5 processor provides responsive performance for everyday multitasking, web browsing, document editing, and light creative work such as photo editing or video streaming.

Which display interface does the 21.5-inch 4K Retina panel use and what resolution does it support?

The built-in 21.5-inch Retina panel drives a native 4K resolution internally; as an all-in-one desktop there is no separate display interface or external cable standard to consider.
