With fourth-generation Intel Core processors, the latest graphics, and faster flash storage, the incredibly advanced 15.4-inch MacBook Pro with Retina display moves even further ahead in performance and battery life. Measuring a mere 0.71 inches and weighing only 4.46 pounds, the MacBook Pro sets a new standard in performance and portability for pro users. The world's highest resolution notebook display with over 5 million pixels - 3 million more than an HD television--the MacBook Pro with Retina display has such a high pixel density that the human eye cannot distinguish individual pixels from a normal viewing distance. This version of the 15.4-inch MacBook Pro with Retina display (model ME293LL/A) features a 2.0 GHz Core i7 quad-core processor, 256 GB of flash storage, and 8 GB of onboard RAM. It's powered by OS X Mavericks, the world's most advanced operating system and built to bring out the best in your Mac. And the MacBook Pro comes pre-loaded with the latest version of the iLife software suite (iPhoto, iMovie, and GarageBand) as well as the iWork productivity suite (Pages, Numbers, and Keynote). The MacBook Pro also includes both a high-speed Thunderbolt port and two USB 3 ports, enabling you to easily connect to external displays and a wide variety of high performance peripherals. With up to 60 percent faster PCIe-based flash storage compared to the previous generation and new 802.11ac Wi-Fi for up to 3x faster wireless, the new MacBook Pro is quicker and more responsive than ever. You'll also get up to 8 hours of battery life while on the go.
