The MacBook is a line of Macintosh portable computers introduced in March 2015 by Apple Inc. The MacBook has a similar appearance to the MacBook Air, but is thinner and lighter, and is available in colors called space gray, silver, gold, and rose gold. It offers a high-resolution Retina Display, a Force Touch trackpad, a redesigned keyboard, and only two ports: a headphone jack and a USB 3.1 Type-C port for charging, data transfer and video output.
In the MacBook product line, the MacBook sits below the MacBook Pro in terms of average specifications. The price is higher than the MacBook Air, which is compensated for by the Retina Display, portability, and higher storage and memory. However, the processor and graphic performance is inferior to the MacBook Air. Many reviewers have also criticized the shallow travel of the redesigned keyboard keys.
On April 19, 2016, Apple updated the Retina MacBook with new sixth-generation Intel Core M processors, Intel HD 515 graphics, faster RAM, longer battery life, faster storage and a new rose gold finish.
On 5 June 2017, Apple again updated the MacBook with Intel Kaby Lake m3, i5, and i7 processors (previously known as m3, m5, and m7). The MacBook also features faster SSD storage and RAM.

Design
The MacBook is designed with thinness in mind; the aluminum enclosure is 13.1 mm at its thickest point at the hinge end of the computer. The MacBook includes Intel Core M processors (Kaby Lake architecture) which requires no fans or heat pipe, allowing the logic board to be much smaller than the one in the MacBook Air. The storage cannot be upgraded. Despite its small size, the computer features a full-sized keyboard and a large trackpad.
The battery was custom-designed to fill the available space in the small enclosure. It uses a new 39.7 watt-hour lithium-polymer terraced battery cell which is advertised to provide "all day" battery life. It is said to last up to 9 hours for Internet browsing or 10 hours of iTunes movie playback. The battery was improved in the 2016 refresh, with Apple claiming to provide 10 hours for Internet browsing, and 11 hours for iTunes movie playback.
The MacBook does not include any beryllium, BFRs, or PVCs in its construction. The display is made of arsenic-free glass and contains no mercury. It is made of recyclable materials such as aluminum and glass, meets Energy Star 6.1 standards, and is rated EPEAT Gold.
Keyboard and trackpad
The MacBook has a new keyboard design and trackpad. Compared to previous models, the individual keys have a larger surface area. Apple replaced traditional scissor mechanism keys with a new, Apple-designed butterfly mechanism keys, making the keyboard thinner and, as Apple claims, individual keys more stable. However, individual keys, especially shift and space, tend to stick because of the extremely short travel. The keyboard's backlight no longer consists of a row of LEDs and a light guide panel, but instead uses a single LED for each key. The letters on the MacBook's keyboard are set in the San Francisco typeface, whereas previous laptops made by Apple used VAG Rounded.
The 2015 MacBook was the first to introduce the Force Touch trackpad, a solid-state trackpad that measures pressure sensitivity, and replicates a click with haptic feedback. The trackpad was later brought to the Magic Trackpad 2. A similar technology is also used in the Apple Watch and newer iPhones.
Ports
To achieve its thin chassis, the MacBook only has a single, multi-purpose USB-C, and a 3.5 mm headphone jack. The port supports transmission speeds of up to 5 Gbit/s, and can be used for charging, output and input of data, and output of video and audio. Apple markets an adapter that can provide a full-size USB connector, and a "Digital AV Multiport Adapter" with a charging pass-through, full-size USB port, and HDMI output. Although Thunderbolt 3 technology uses USB-C connectors, the MacBook's USB-C port does not support Thunderbolt. Thunderbolt devices, such as storage media and the Apple Thunderbolt Display, are not compatible with the MacBook. Shortly after the MacBook's introduction, various companies began announcing cables and adapters for the USB-C port.

Reception
Reception for the new MacBook has been generally positive, with critics praising the design and overall quality of the product. However, several described it as a limited first-generation product designed to avoid extensive use until the MacBook reached greater maturity, and its price dropped sufficiently for mainstream adoption. The slow performance of the Intel Core M processor was regarded as the new MacBook's main deficiency, relative to the cheaper and faster MacBook Air and Pro. Among the other criticisms of the new MacBook are the lack of various popular ports, particularly USB Type-A ports, which limits data transfer and overall convenience without the use of an adapter.
The keyboard also received criticism as being poor for long-term use: developer Marco Arment described the laptop's build and small size as "absolutely amazing, revolutionary, and mind-blowing... until you need to use the keyboard for something." He also criticised the trackpad as worse than on previous MacBooks, and said that he would be returning the model he had bought.
Apple's introduction of a gold MacBook finish has been cited as an example of positioning itself as a luxury-style brand. The choice follows the introduction of the gold iPhone 5S after Apple found that gold was seen as a popular sign of a luxury among Chinese customers. Noting the appeal of Apple introducing gold laptops, IT and science journalist Casey Johnston commented, "I'm marrying one."
Technical specifications
Notes:
1 Apple states the processor specifications as "1.1 GHz, turbo boost 2.4 GHz ", "1.2 GHz, turbo boost 2.6 GHz", and "Configurable 1.3 GHz, turbo boost 2.9 GHz", but there are no Intel Core M processors that correspond to these specific specifications that have been publicly announced. It can be inferred that Apple adapts the newest Core M models launched in Q4'14, which support Configurable TDP. The Core M-5Y31 runs at a base frequency of 900 MHz, M-5Y51 at 1.1 GHz and M-5Y71 at 1.2 GHz, the clock speeds of which seem to have been raised up to 1.1 GHz, 1.2 GHz and 1.3 GHz, respectively. All of three models match the Max Turbo Frequency specification given by both Apple and Intel.
