Apple MacBook Pro Retina 2012 A1398 Core i7 3720QM 2.6GHz 16GB 512GB SSD 15.4"

Heralded as the "most advanced Mac ever built," the officially dubbed "MacBook Pro with Retina Display" models combine a beautiful high-resolution LED-backlit 15.4" widescreen 2880x1800 (220 ppi) "retina" display with a thin, sleek case design that weighs a bit less than 4.5 pounds (2.02 kg). Curiously, these systems are not branded on the display bezel like earlier MacBook Pro models.

Somewhat controversially, the Retina Display models also are an essentially "sealed" design with RAM that is soldered in place and cannot be upgraded after purchase, storage that is not intended to be upgraded after purchase, and a battery that cannot be replaced readily even by technical users or third-parties, either.

This particular model -- the MacBook Pro "Core i7" 2.6 15-Inch (Mid-2012 Retina Display) features a 22 nm "Ivy Bridge" 2.6 GHz Intel "Core i7" processor (3720QM), with four independent processor "cores" on a single silicon chip, a 6 MB shared level 3 cache, 8 GB of onboard 1600 MHz DDR3L SDRAM (which cannot be upgraded after purchase), 512 GB of flash storage, dual graphics processors -- a NVIDIA GeForce GT 650M with 1 GB of dedicated GDDR5 memory and an "integrated" Intel HD Graphics 4000 graphics processor that shares system memory, as well as an integrated 720p FaceTime HD webcam. It does not have an internal optical drive.

Connectivity includes 3-stream AirPort Extreme (802.11a/b/g/n), Bluetooth 4.0, two USB 3.0 ports, two "Thunderbolt" ports, an HDMI port, an audio in/out port, and an SDXC card slot. It does not have Gigabit Ethernet or Firewire "800," although adapters are available at extra cost.

In addition, this model has a backlit keyboard, a "no button" glass "inertial" multi-touch trackpad, a "MagSafe 2" power adapter, and an internal, sealed battery that provides an Apple estimated 7 hours of battery life (when new).

A 3mth warranty is included for your peace of mind.
