Apple iMac MD093LL/A-C desktop PC 2.7 GHz i5 8 GB 1 TB HDD 21.5" OS X 10.8 Grade C

Refurbished iMac for basic desktop use

This Apple iMac MD093LL/A-C is a refurbished all-in-one desktop with a 21.5-inch display, Intel Core i5 2.7 GHz quad-core processor, 8 GB of memory and a 1 TB hard drive. It ships with OS X 10.8 Mountain Lion, keyboard and mouse included. The Grade C rating means visible cosmetic wear is present. It suits buyers who need a simple macOS workstation for light productivity or media playback.

All-in-one build with integrated peripherals

The iMac houses the logic board, storage and NVIDIA GeForce GT 640M graphics behind the 21.5-inch screen, so no separate tower or monitor cables are required. A wired keyboard and mouse are supplied in the box, giving an instant desktop setup. Because the system uses a mechanical hard drive rather than solid-state storage, boot and application launch times will be slower than on modern SSD-equipped Macs. The integrated graphics share system memory and are not suited to demanding 3D workloads.

Replaces older Core 2 Duo or single-core Macs

Moving from a Core 2 Duo iMac or earlier all-in-one to this quad-core model adds four 64-bit cores and 8 GB of RAM, which improves multitasking and 10.8-era application responsiveness. The jump is worthwhile if you must run Mountain Lion-compatible software on a complete, ready-to-use system. Buyers who need SSD speed, Metal-capable graphics, macOS versions beyond 10.8 or a flawless exterior should consider a different unit.
