- Apple designed this MacBook with thinness in mind.
- Indeed, the aluminum enclosure is 13.1 mm at its thickest point at the end of the computer next to the place where it pivots.
- Intel Core M processors (Skylake architecture) require no fans or heat pipe, allowing the logic board to be much smaller than the one of the MacBook Air.
- However, storage upgradeability is no longer possible, and the MacBook still features a full-sized keyboard and trackpad.
- The Retina MacBook (released in 2015) battery was redesigned to a custom shape to fill the available space in the smaller enclosure.
- The battery was improved in the 2016 refresh. For a new battery Apple claimed to provide ten hours for Internet browsing, and eleven hours for iTunes movie playback.
- As to ecology and environment issues, the MacBook does not include any beryllium, BFRs, or PVCs in its construction.
- The computer’s display is made of arsenic-free glass and contains no mercury.
- The device is made of recyclable materials such as aluminum and glass, meets Energy Star 6.1 standards, and is rated EPEAT Gold.
- Many reviewers have criticized the Retina MacBook (April 2015) for its keyboard being less comfortable than that on the MacBook Air.
- However, 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. Apple also claims that individual keys are 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 new Macbook’s keyboard are set in San Francisco fonts, whereas previous MacBooks used VAG Rounded.
- Retina Display MacBook (April 2015) was the first to introduce the Force Touch trackpad, allowing for pressure sensitivity, and replicating a click with haptic feedback.
- The trackpad was later brought to the MacBook Pro line, and the Magic Trackpad. Apple uses similar technology the Apple Watch and new iPhone models. Apple had to remove all prviously existing ports to achieve the thinness, except the headphone jack. A USB Type-C port was placed instead.
- The headphone jack supports headphones with integrated microphone. It is located on the right side of the MacBook 8,1 and is located right next to two openings that house the microphone for handsfree talk.
- The USB-C port allows charging, output and input of data, video and audio. Adapters can be used to offer backward compatibility. Thunderbolt devices cannot function, however, since there is no adapter available for that function.
- Shortly after the MacBook’s introduction in April, 2015, various companies began announcing cables and adapters for the USB Type-C port.
- Unlike other USB connectors, USB Type-C is reversible.
- The lack of various popular ports has been the source of one of the main criticisms, the lack of USB type-A ports was particularly mentioned, as the situation limits data transfer and overall convenience without the use of an adapter.
- The inclusion of the low-power, but slower Intel Core M processor was also criticized by many users.
