The unibody enclosure of the MacBook is constructed from a single block of aluminum, making the new MacBook fundamentally thinner, stronger, and more resilient with fit and quality we've never even imagined before. The prior MacBook Pro features an internal backbone and a thin, bowl-shaped exterior. The new MacBook Pro has no such structure inside its unibody enclosure.
Instead, it's completely hollow, which allows it to be even thinner and lighter. It also means it's much stronger, with no internal parts that could break off or come loose over time.
The new MacBook Pro is 2.5 inches (63 mm) thick, compared with 3.5 inches (90 mm) for the old one. It weighs 4 pounds (1.8 kg), compared with 5 pounds (2.3 kg) for the old one. It has a screen resolution of 1366 by 768 pixels, compared with 1440 by 900 for the old one. It has Intel Core i5, i7, or i9 processors, depending on how you configure it. It has up to 16 GB of memory and up to 1 TB of storage space.
All things considered, then, the new MacBook Pro is actually less expensive than the old one!
It's worth mentioning that not all models are created equal.
Apple's new MacBook and MacBook Pro have precise unibody shells cut from an extruded block of aluminum, allowing them to be even thinner while yet maintaining robust durability and a stronger, cleaner, and more polished design. The new machines also feature solid-state drives instead of traditional hard disks for their storage systems.
The original MacBook was the first laptop designed specifically by Apple, and it proved so successful that Apple has continued to improve on the concept with each new model release. The current lineup includes the 13-inch MacBook Air, which is aimed at consumers who want a portable computer that doesn't weigh much or cost too much; the 13-inch MacBook, which retains the Aluminum Unibody construction but replaces the Air's Intel Atom processor and limited RAM capacity with a faster Core i5 unit and 8GB of memory; and the 15-inch MacBook Pro, which adds a high-resolution LED display as well as an Intel Core i5 or i7 processor to its predecessor. All three models are available in four colors: space gray, silver, gold, and black.
MacBook Pros are now available with Touch ID, the fingerprint sensor that debuted on the iPhone 5s last year. It can be used to authenticate users in lieu of a password, making it easier for those who have access to your Mac to log in without having to enter a password.
Aluminum The 13-inch MacBook Air enclosure is comprised of aluminum, which is highly sought after by recyclers. The materials used in this model are shown in the chart below. Corrugated cardboard with over 30% recycled material and molded fiber with 100% recycled content are used in the packaging for the 13-inch MacBook Air. Aluminum is also used for other components such as the display bezel and bottom cover.
Magnesium The 12-inch MacBook Air is made of 70 percent magnesium and 30 percent plastic. Magnesium is two to three times more conductive than aluminum and has a silver color that contrasts nicely with the black background of the notebook. It's also lighter than aluminum.
Glass A glass panel displays computer graphics instead of a screen. This technology is used on many tablets and smartphones but not typically on desktop computers because they tend to be heavier and less durable when made of glass. The glass panel on the 12-inch MacBook Air is broken into smaller pieces than usual to reduce the weight of the laptop.
Silicon The logic board, battery, disk drives, and other components inside the MacBook Air are made from silicon. Silicon is the most common element on the planet and is found in everything from bread to bulldozers. It is also used to make computer chips, which are the "brains" of every computer device. Silicon chips come in two types: N-type, which contain nitrogen; and P-type, which contain phosphorus.
2011 In late 2009, Apple released the unibody polycarbonate MacBook, the third design iteration of the MacBook series, in black and white. The MacBook was only available for a brief period before being discontinued in mid-2011, after the release of the MacBook Air. It was replaced with the MacBook Pro with Retina display in October 2011.
The final white MacBook was announced on September 9, 2011, just over two months after the release of the original black model. It was given an official retirement date of October 23, 2011. However, some store inventory from that week's shipment was not processed by the factory until later in the month, meaning some remaining white MacBooks were sold through those stores has well as online retailers like Amazon. These sales eventually depleted the supply and caused the battery replacement program mentioned below to be initiated.
As part of its commitment to protect the environment, Apple will be closing its manufacturing facility in Broekhuizen, Netherlands by the end of 2012. The company says it will continue to support the MacBook line with service centers around the world and will provide software updates as they become available.
The white color option was very popular among consumers who wanted a clean look without any color distractions. Even today, many think the white model is the classic Mac design while others prefer the black version.
