Product Overview
The 15.4″ MacBook Pro Notebook Computer with Retina Display from Apple is a powerful notebook computer with an innovative, ultrathin, ultraportable aluminum unibody design. It is loaded with advanced power management features and an integrated lithium polymer battery, which work together to provide long hours of wireless web browsing. The widescreen, LED-backlit IPS screen has a glossy finish and a native resolution of 2880 x 1800. With 220 pixels per inch, this MacBook Pro has a pixel count of over 5 million. Visuals are handled by integrated Intel Iris Pro Graphics.

Powerful

The system is powered by a quad-core 4th generation Crystalwell 2.2 GHz Intel Core i7 processor. The 4th-gen Crystalwell processor uses low voltage for improved battery life without sacrificing performance. The MacBook Pro with Retina Display also has 8GB of onboard 1600MHz DDR3L RAM, 256GB of PCIe-based flash storage, and an SDXC media card slot. You’ll be able to connect to the Internet with high-speed 802.11ac Wi-Fi. The MacBook Pro also supports a/b/g/n Wi-Fi networks as well. The MacBook Pro also features built-in Bluetooth 4.0, which allows you to connect wireless headphones, keyboard, mice and other compatible peripherals without a hassle.

East Connection

This MacBook Pro has dual Thunderbolt 2 ports, a high-speed interface that can move data at an amazing 20 Gbps, which is four times that of the USB 3.0 standard. Speaking of USB 3.0, Apple still supports USB 3.0. This MacBook Pro now features two USB 3.0 ports so you no longer have to buy an adapter, but can use USB 3.0-compliant devices natively as well. There is also a MagSafe 2 power port, which uses a magnetic connector that safely disengages from the computer when accidentally pulled.

Please note that MagSafe 2 is not compatible with MagSafe adapters.

Keyboard

The computer features a comfortable backlit chiclet-style keyboard, which features space between each key for improved accuracy and comfort when typing. It also sports a glass multi-touch trackpad with a clickable design. Rather than having a separate button for mouse clicks, the entire surface of the pad is clickable. This increases the active surface area and allows you to quickly click without having to maneuver to the bottom of the trackpad. The trackpad also fully supports multi-touch gestures. You can tap the trackpad with one finger to click, tap with two fingers to right-click, scroll through documents using two fingers, pinch to zoom, navigate through Safari or iPhoto with three-finger left and right swipes or use two fingers to rotate a photo or PDF.

Retina Display

The 15.4″ display of this MacBook Pro features over 5 million pixels. The pixel density is so high your eyes won’t be able to discern individual pixels. Now with a 2880 x 1800 native resolution, you can see more of your high-resolution images onscreen with pixel-for-pixel accuracy. The Retina display also reduces glare while maintaining incredible color and quality. In fact, it has a 29 percent higher contrast ratio than a standard MacBook Pro display. IPS technology gives you a wide, 178-degree view of everything on the screen, so you’ll see the difference at practically any angle.

Quad-Core 4th-Gen Crystalwell Intel Core i7 Performance

The 4th-gen Crystalwell Intel Core i7 processor with a state-of-the-art 22-nanometer single-die microarchitecture in this MacBook Pro provides fast quad-core performance. Intel Hyper-Threading technology allows two threads to run simultaneously on each core. The quad cores can run at a stock speed of 2.2 GHz. The processor can be overclocked up to 3.4 GHz, thanks to Intel Turbo Boost 2.0 technology. With a 6MB L3 cache and 16GB of onboard 1600 MHz DDR3L RAM memory, this MacBook Pro can run professional applications like Aperture and Final Cut Pro with ease.

Integrated Intel Iris Pro Graphics

The MacBook Pro features Iris Pro Graphics with 128MB of embedded memory, which accelerates processor- and graphics-intensive tasks by acting as an ultrafast cache.

All Flash Storage

This MacBook Pro feels incredibly fluid and responsive. It’s all thanks to its PCIe-based flash storage, which gives you up to 60 percent faster read and write performance than its predecessor. When you use apps like Final Cut Pro or Aperture, you can perform even the most demanding tasks right from your internal storage. And since this MacBook Pro comes with 256GB of flash storage, you can keep all your important files with you, including large video and photo libraries. Flash doesn’t have any moving parts, which makes it reliable and quiet. And flash storage is extremely energy efficient, which means your MacBook Pro also has the ability to stay in standby mode for up to a month without having to be plugged in.

Thunderbolt 2

The MacBook Pro features the next-gen Thunderbolt 2. It delivers twice the throughput, providing up to 20 Gbps of bandwidth to each external device. So you’re more than ready for the next generation of high-performance peripherals and displays. You can connect massive amounts of storage and add a PCI expansion chassis. And since each Thunderbolt 2 port allows you to daisy-chain up to six peripherals, you can go all out by plugging in up to 12 external devices via Thunderbolt alone.

HDMI, USB 3.0, SDXC

The MacBook Pro with Retina Display also has dual USB 3.0 ports, an HDMI port and an SDXC card slot, so you can build an entire professional studio with the MacBook Pro as its centerpiece.

iCloud

iCloud stores your content and lets you access your music, photos, calendars, contacts, documents, and more from whichever device you’re on. So you’ll be able to access your photos, reminders, notes, music, and videos from your iOS devices right on this MacBook Pro.

Incredibly Powerful

It may be thin and light, but this MacBook Pro is also incredibly powerful. To achieve all that in a single design required relentless focus and a willingness to make bold decisions. Bulky legacy technologies like the spinning hard drive and optical disc drive were left behind in favor of higher-performance technologies – all-flash storage, for example. It’s much faster and far more reliable than a traditional hard drive. And it takes up 90 percent less space.

Ultrathin and Ultraportable

This MacBook Pro is ultrathin and ultraportable, resembling more a MacBook Air than a MacBook Pro. It is 0.75″ thin and weighs 4.46 pounds, so this MacBook Pro embodies the performance of a MacBook Pro but has the body of a MacBook Air.
