The MacBook (marketed as the "New Macbook") is a line of Macintosh portable computers introduced in March 2015 by Apple Inc.[1] The MacBook has a similar appearance to the MacBook Air, but is thinner and lighter,[2] and is available in space gray, silver and gold. Other features include a high-resolution Retina Display, a Force Touch trackpad, a redesigned keyboard, and only two ports: a headphone jack and USB 3.1 Type-C port for charging, data transfer and video output.

In the Macintosh product line, the MacBook sits below the MacBook Pro in terms of average specifications, while compared to the MacBook Air its features reflect different priorities. The base model MacBook has a 256GB SSD and 8GB of RAM, both double that of the MacBook Air base models, and a better display, but the MacBook's 1.1GHz processor clock speed is slower than the latter's 1.6GHz processor. Many reviewers have also criticised its keyboard for being more uncomfortable than that on the MacBook Air.[3][4][5][6]

The MacBook is designed for thinness, the aluminum enclosure is 13.1 mm at its thickest point.[7] The MacBook includes Intel's Core M processors (Broadwell architecture) which requires no fans or heat pipe, which allows the logic board to be smaller than the one of the MacBook Air. The computer features a high-resolution 12" IPS 2304×1440 Retina Display and a full-size keyboard, as well as a large trackpad that responds to multi-touch gestures – such as pinching, swiping and rotating – as well as pressure.

The battery was redesigned to a custom shape to fill the available space in the smaller enclosure. It uses a new 39.7 watt-hour lithium-polymer terraced battery cell which is said to provide "all day" battery life. It is said to last up to 9 hours for internet browsing or 10 hours of iTunes playback.[8]

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 and trackpad. Compared to previous models, the individual keys have a larger surface area. Apple replaced the scissor-like mechanism with a butterfly mechanism, making the keyboard thinner overall and, as Apple claims, individual keys more stable. 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 San Francisco, whereas previous MacBooks used VAG Rounded.[9]

Apple replaced the click mechanism of the trackpad with force sensors and a linear actuator called Taptic Engine to provide haptic feedback whenever the trackpad is pressed down. Similar technology is used in the Apple Watch.


The MacBook has a single port and a jack: a USB 3.1 Type-C (generation 1, up to 5 Gbit/s) port on the left side and a 3.5mm headphone jack on the right. The USB Type-C port serves as the MacBook's power source, replacing Apple's proprietary MagSafe connector. Through adapters it is also capable of interfacing with DisplayPort, HDMI, VGA, previous USB connectors and Ethernet, among other things.[10] Some devices such as the Apple Thunderbolt Display, which is not backward compatible with USB 3.0, cannot be used. Shortly after the MacBook's introduction, various companies began announcing cables and adapters for the USB Type-C port.[11] Unlike other USB connectors, USB Type-C is reversible.[12]


Reception for the new MacBook has been generally positive, with critics praising the design and overall quality of the product, though several described it as a limited first-generation product to avoid for extensive use until the category reached greater maturity.[13][14][15][16][17][18] Among the main criticisms 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, and the inclusion of the low-power but slower Intel Core M processor.

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."[19] He also criticised the trackpad as worse than on previous MacBooks, and said that he would be returning the model he had bought.[20]

Soon after the launch, the 2015 MacBook became the object of a humorous Ratones Coloraos interview meme, featuring Spanish comedian El Risitas in Jesús Quintero's show. In the meme, a Spanish-language interview was given subtitles claiming to present an engineer who worked on the prototype of this MacBook laughing at how limited its features were. Within a month of its uploading, the video received over five million views on YouTube.[21]

Apple's introduction of a gold style has been cited as an example of its positioning Apple 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 product among Chinese customers.[22] Noting the appeal of Apple introducing gold laptops, IT and science journalist Casey Johnston commented, "I'm marrying one."[23]

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.
