The 12-inch MacBook (also called the Retina MacBook, officially marketed as the new MacBook) is a discontinued Mac laptop made by Apple, which sat between the MacBook Air and MacBook Pro in Apple's laptop lineup. It shares the same name as its predecessor that was discontinued three years prior to the release of this one.

Introduced in March 2015, it was more compact than any other notebook in the MacBook family at the time and included a Retina display, fanless design, and a Butterfly keyboard with lower key travel. It only had a single USB-C port, used for both power and data. It was revised in 2017, and discontinued in July 2019, a year after the release of the MacBook Air with Retina display.

Overview

[edit]

The MacBook was announced at an Apple special event on March 9, 2015, and was released a month later on April 10. It employed Intel's Broadwell Core M processors at a TDP of around 4.5 watts to allow for a fanless design and a logic board that is much smaller than in previous MacBooks. It had a similar appearance to the MacBook Air, but was thinner and lighter, offered (at the time of introduction) more storage and memory, and a higher-resolution 2304×1440 Retina display, but lower processor and graphics performance.[2] The MacBook has at times been available in space gray, silver, and gold finishes.

USB-C on MacBook

The MacBook has only one port, a single, multi-purpose USB-C port; it was the first Mac with USB-C. The port supports transmission speeds of up to 5 Gbit/s, and can be used for data, and audio/video output, and charging; it was the first MacBook without MagSafe charging. Apple markets an adapter that can provide a full-size USB-A connector, and a "Digital AV Multiport Adapter" with a charging pass-through, full-size USB-A port, and HDMI output.[3] Although Thunderbolt 3 technology uses USB-C connectors, the MacBook's USB-C port does not support Thunderbolt. It was one of only two Macs, along with the 2012 Mac Pro, to not support Thunderbolt since it was introduced to Macs in 2011.[4] Thunderbolt devices, such as storage media and the Apple Thunderbolt Display, are not compatible. Shortly after the MacBook's introduction, various companies began announcing cables and adapters for the USB-C port.[5]

Despite its small size, it features a full-sized keyboard and a large trackpad. The MacBook introduced a new Butterfly keyboard, with traditional scissor mechanism keys replaced with a new, Apple-designed butterfly mechanism, making the keyboard thinner and, as Apple claims, individual keys more stable. The keyboard's backlight no longer consisted of a row of LEDs and a light guide panel, but instead used a single LED for each key.[6] It also introduced 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 and the 2015 MacBook Pro. A similar technology (3D Touch) is also used in the Apple Watch and introduced with the iPhone 6S.

The aluminum enclosure is 13.1 mm at its thickest point at the hinge end.[7] The battery was custom-designed to fill the available space in the small enclosure. It uses a 39.7 watt-hour lithium-polymer terraced battery cell which was advertised to provide "all day" battery life. Apple claimed nine hours of Internet browsing or ten hours of iTunes movie playback. The battery was improved in the 2016 refresh, with Apple claiming ten hours for Internet browsing, and eleven hours of iTunes movie playback.[8] The MacBook did not include any beryllium, BFRs, or PVCs in its construction. The display was made of arsenic-free glass. It was made of recyclable materials such as aluminum and glass, meets Energy Star 6.1 standards, and was rated EPEAT Gold.

On April 19, 2016, Apple updated the MacBook with Skylake Core M processors, Intel HD 515 graphics, faster memory, longer battery life, faster storage[9] and a new rose gold finish.[10]

On June 5, 2017, Apple updated the MacBook with Intel Kaby Lake m3, i5, and i7 processors (previously known as m3, m5, and m7). It featured the second-generation butterfly keyboard, which introduced new symbols for the control and option keys. It also features faster storage and memory.[11] On October 30, 2018, Apple quietly eliminated two color options (rose gold and the original gold) and added a new color option (new gold) to match the Apple devices's 2018 color scheme.[12][13]

On July 9, 2019, Apple quietly discontinued the MacBook line.[14] On June 7, 2021, Apple announced macOS Monterey which dropped support for early 2015 model MacBook.[15] On June 30, 2021, Apple added the early 2015 model MacBook to its "vintage products" list, making it eligible for only limited product support.[16] On June 6, 2022, Apple announced macOS Ventura which dropped support for the early 2016 model MacBook. On June 5, 2023, Apple announced macOS Sonoma which dropped support for the 2017 model, marking the end of macOS updates to the family. On June 30, 2023, Apple added the early 2015 model MacBook to its "obsolete products" list, making it end of product support and discontinues all hardware service.

Design

[edit]
A side view of the MacBook

Externally, the MacBook follows the design of the MacBook Air with a tapered aluminum enclosure. It has a flush screen with black bezels similar to the MacBook Pro. The Apple logo on the rear of the display is glossy and opaque, rather than backlit and white as seen on every Apple notebook since the 1999 PowerBook G3 and 2001 iBook.[17][18]

The design was very similar to the Touch Bar MacBook Pro (2016 - 2019) and the Retina MacBook Air (2018 - 2019), with a glass force touch trackpad, butterfly keyboard, and retina screen.[19]

The letters on the MacBook's keyboard are in the San Francisco typeface, whereas previous notebooks made by Apple used VAG Rounded.[6]

Apple updated the typeface of the model name MacBook on at the bottom of the screen bezel to San Francisco in the 2017 model.

Reception

[edit]

Reception for the MacBook was mixed. Critics praised the design and overall quality of the product, with some regarding it as a potential successor to the MacBook Air, as the Air had an aging design and low resolution screen.[20] However, Apple continued to offer the MacBook Air while selling the MacBook at considerably higher price. Several described the MacBook as a limited first-generation proof-of-concept design for early adopters, and recommended against buying the MacBook until it reached greater maturity, and its price dropped sufficiently for mainstream adoption.[21][22][23][24][25][26] 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 MacBook Pro.[27] Among the other criticisms of the new MacBook are the lack of various popular ports, particularly USB Type-A ports, and that it only contains a single port which limits data transfer and overall convenience without the use of an adapter.[28]

The keyboard received considerable criticism as being poor for long-term use: developer Marco Arment described the notebook's build and small size as "absolutely amazing, revolutionary, and mind-blowing... until you need to use the keyboard for something."[29] He also criticised the trackpad as worse than on previous MacBooks, and said that he would be returning the model he had bought.[30]

A report by AppleInsider had claimed that the updated butterfly keyboard fails twice as often as previous models, often due to particles stuck beneath the keys.[31] Repairs for stuck keys have been estimated to cost more than $700.[32] In May 2018, two class action lawsuits were filed against Apple regarding the keyboard issue with one alleging a "constant threat of nonresponsive keys and accompanying keyboard failure" and accusing Apple of not alerting consumers to the issue.[33] In June 2018, Apple announced a Service Program to "service eligible MacBook and MacBook Pro keyboards, free of charge".[34]

The 12-inch MacBook was an ultraportable laptop computer family designed, manufactured, and sold by Apple Inc. from 2015 to 2019, positioned between the MacBook Air and MacBook Pro in Apple's lineup as the thinnest and lightest Mac notebook at the time. It featured a fanless aluminum unibody enclosure, a 12-inch Retina display with 2304-by-1440 resolution at 226 pixels per inch, and a single USB-C port serving as the sole means for charging, data transfer, and video output. The device weighed just 2.03 pounds (0.92 kg) and measured 0.14 to 0.52 inches (0.35 to 1.31 cm) in height, emphasizing extreme portability over expandability. Apple unveiled the 12-inch MacBook on March 9, 2015, at a special event in , with shipping beginning on April 10, 2015. The initial model was powered by a 1.1 GHz or 1.2 GHz dual-core M processor (with Turbo Boost up to 2.4 GHz or 2.6 GHz), 8 GB of LPDDR3 RAM, and either 256 GB or 512 GB of PCIe-based flash storage, starting at a price of $1,299. Key innovations included a full-size butterfly-mechanism keyboard that was 34% thinner than previous designs, a Touch trackpad with haptic feedback, and a battery life of up to 9 hours of wireless web browsing or 10 hours of video playback from its 39.7-watt-hour lithium-polymer battery. Available in silver, gold, and space gray finishes, it introduced to Apple's portfolio and supported HD Graphics 5300 for external displays up to 3840x2160 resolution. The lineup received minor updates in subsequent years to improve performance while retaining the core design. In early 2016, Apple refreshed the model with Intel Core m3, m5, or configurable m7 processors (Turbo Boost up to 3.1 GHz), faster 1866 MHz RAM, a 41.4-watt-hour battery for up to 10 hours of web use or 11 hours of video, and added a rose gold color option. The 2017 version further enhanced capabilities with a 1.2 GHz Core m3 (configurable to 1.3 GHz i5 or 1.4 GHz i7), optional 16 GB RAM, Intel HD Graphics 615, Bluetooth 4.2, and extended battery life to 10 hours web or 12 hours video playback. Throughout its run, the 12-inch MacBook maintained its single-port architecture, stereo speakers, dual microphones, and 480p FaceTime HD camera, prioritizing a silent, efficient operation without internal fans. Apple discontinued the 12-inch MacBook on July 9, 2019, without a formal announcement, as it removed the product from its online store alongside updates to the and 13-inch . The decision was driven by the refreshed , which adopted a , better performance, and a lower starting price of $1,099, effectively absorbing the ultraportable segment previously occupied by the 12-inch model. As of 2025, the 12-inch MacBook (2015–2019 models) is considered obsolete by Apple, with no hardware service available worldwide, and software support for macOS has ended or is impending due to the shift to Apple Silicon processors. The 12-inch MacBook received widespread praise for its groundbreaking design and portability but faced criticism for its limited performance and connectivity. Reviewers highlighted its "unbelievable" thinness, stunning , and premium build as engineering triumphs, often calling it the most impressive laptop since the original . However, the single port was a frequent point of contention, requiring adapters or docks for most workflows, and the low-power processors were deemed underpowered for demanding tasks compared to the or Pro. Later models addressed some performance issues, earning scores like 8.5/10 from for improved speed and the adopted butterfly keyboard from higher-end Pros. Overall, it appealed to users prioritizing mobility and aesthetics over versatility, cementing its legacy as a bold but polarizing experiment in minimalism.

Overview

Product Positioning

The 12-inch MacBook was positioned as an ultra-portable within Apple's lineup, bridging the gap between the larger 13-inch and the more powerful models by prioritizing extreme thinness, lightness, and extended battery life over high-end performance capabilities. At just 13.1 mm thick and weighing only 2 pounds, it represented the thinnest and lightest Mac notebook ever produced at the time, with a fanless enabling silent operation and up to 9 hours of wireless web browsing or 10 hours of video playback. This focus on portability made it a specialized option for users who valued mobility and in a device featuring a 12-inch . It targeted students, frequent travelers, and users with light computing needs, such as web browsing, document editing, email management, and media consumption, rather than demanding professional workloads like or . The device's streamlined form factor and single port for charging and connectivity further emphasized its role as a secondary or on-the-go companion , appealing to those willing to trade expandability for compactness. The 2015 model marked Apple's return to the 12-inch laptop category with an all-aluminum unibody construction, the first such design in that form factor since the discontinuation of the polycarbonate 12-inch MacBook in 2008. This revival updated the concept with modern materials and integration, while maintaining the emphasis on portability that defined the original line. At launch, the base configuration started at $1,299, positioning it as a premium entry-level option above budget alternatives but below the pricier .

Development and Announcement

The development of the 12-inch MacBook originated in amid Apple's ongoing initiative to produce thinner and lighter laptops, building on the unibody redesign of the introduced in 2010. Reports from that year indicated that Apple had initiated low-volume production of components for a new ultra-thin MacBook model, targeting a potential launch by late or early 2015 to emphasize portability and in its laptop lineup. Apple officially announced the 12-inch on , , during a media event at its Town Hall in , presenting it as an entirely new line of notebooks dubbed simply the "new ." The device was positioned as Apple's thinnest and lightest to date, measuring just 13.1 mm thick and weighing 2 pounds, with a focus on integrating advanced features into a compact form factor. It launched in three colors—gold, silver, and space gray—and shipped beginning April 10, , equipped with dual-core Intel Core M processors based on the Broadwell architecture, available in configurations starting at 1.1 GHz. In April 2016, Apple quietly updated the MacBook without a formal event, introducing sixth-generation Intel Core m3, m5, and m7 processors (Skylake architecture), faster graphics, and the new rose gold color option alongside the existing palette. This refresh also enhanced storage speeds and battery life, maintaining the model's emphasis on ultra-portability. A further update arrived on June 5, 2017, replacing the Core m-series with seventh-generation Intel Core m3, i5, and i7 processors (Kaby Lake architecture) and expanding RAM options to a maximum of 16 GB of LPDDR3, while retaining the same color choices including rose gold.

Design and Build

Physical Construction

The 12-inch MacBook employs a tapered aluminum unibody enclosure, machined from a single block of aluminum for structural integrity and a premium finish. This design measures 11.04 inches (28.05 cm) in width, 7.74 inches (19.65 cm) in depth, and tapers in height from 0.14 inches (0.35 cm) at its thinnest front edge to 0.52 inches (1.31 cm) at the rear hinge area across all models from 2015 to 2017. The chassis weighs 2.03 pounds (0.92 kg) across all color options. The laptop adopts a fanless , eliminating fans to achieve completely silent operation during use. Heat dissipation relies on through the aluminum itself, which serves as a conductor to spread and radiate warmth evenly without mechanical components. This approach aligns with the device's emphasis on and portability, though it limits sustained high-performance tasks to prevent thermal throttling. Available colors evolved across generations, starting with silver, gold, and space gray upon its launch. Rose gold was introduced in the update, expanding aesthetic options while maintaining the same anodized aluminum finish for color consistency and scratch resistance. Durability is enhanced by precision CNC machining of the aluminum body, which provides rigidity despite the ultra-thin profile, along with reinforced hinges that support the display's full without flexing. Later models from 2017 incorporate a highly recyclable aluminum , contributing to environmental goals, including beryllium-free construction and compliance with standards. The battery is seamlessly integrated into the unibody , with capacity increasing from 39.7 watt-hours in the 2015 model to 41.4 watt-hours in later models starting in , enabling up to 10 hours of wireless web browsing on a full charge. This design maximizes internal space efficiency, positioning the lithium-polymer cells to support the device's all-day portability claims.

Input Devices

The 12-inch MacBook featured Apple's butterfly keyboard mechanism, introduced with the 2015 model as a low-profile design that replaced the traditional scissor-switch architecture to achieve a thinner profile while maintaining key stability through a lever-like structure with a dome under each . This mechanism made the overall keyboard 34 percent thinner than previous models, with individual LED backlighting for all 78 (U.S.) or 79 (ISO) keys, including a full row of 12 physical function keys and dedicated , adjusted for the compact . An automatically illuminates the keys in low-light conditions. However, the butterfly design proved prone to mechanical failures, such as stuck or unresponsive keys and repeated character input, often triggered by minor debris accumulation under the shallow . The laptop's trackpad integrates haptic feedback via an internal Taptic Engine to simulate physical clicks without moving parts, enabling pressure-sensitive interactions across its entire surface. This allows for advanced gestures, clicks for right-clicking or contextual actions, and variable pressure levels for tasks like drawing or scrolling, with customizable sensitivity settings in macOS. The trackpad's larger size relative to the device's 11.04-inch width provides precise cursor control despite the overall compactness. Positioned at the top center of the display bezel, the 12-inch MacBook includes a HD webcam for video calls and basic imaging, supporting standard macOS camera features without advanced capabilities like higher resolution or depth sensing.

Hardware Specifications

Processor and Performance

The 12-inch MacBook utilized low-power dual-core processors from the Broadwell, Skylake, and architectures across its model years, optimized for the device's fanless, ultrathin design with a 5W (TDP) envelope. The initial Early 2015 model featured M processors at base clock speeds of 1.1 GHz to 1.3 GHz, with Turbo Boost capabilities up to 2.9 GHz, enabling efficient handling of everyday while prioritizing battery life and portability. Subsequent updates in and 2017 refined this approach with newer generations, incrementally improving clock speeds and efficiency without altering the core philosophy of .

These processors integrated Intel HD Graphics, specifically the HD 5300 in the 2015 model, HD 515 in 2016, and HD 615 in 2017, all sharing system memory without a discrete GPU option, which limited graphical demands to basic tasks like web browsing and light media playback. The absence of active cooling meant performance was calibrated for short bursts rather than sustained workloads, with the device excelling in productivity applications such as document editing and web-based services when paired with up to 16 GB of LPDDR3 memory. In benchmarks, the processors delivered single-core Geekbench scores ranging from approximately 2,000 to 3,000 in 4, reflecting solid responsiveness for ultraportable use but underscoring limitations in multi-threaded scenarios. Under prolonged loads, thermal constraints in the fanless caused clock speeds to by up to 10-30%, reducing performance to prevent overheating and prioritizing longevity over peak output. This made the MacBook ideal for casual users but less suitable for demanding tasks like or compilation, where sustained power draw exceeded the passive design's capacity.

Memory, Storage, and Display

The 12-inch MacBook utilized soldered LPDDR3 memory that could not be upgraded by users after purchase. The Early 2015 model was equipped with 8 GB of 1600 MHz LPDDR3 RAM. The Early 2016 model upgraded to 8 GB of 1866 MHz LPDDR3. The 2017 model retained the 1866 MHz LPDDR3 standard but introduced an optional configuration of 16 GB, doubling the capacity available at the time of purchase. Storage in the 12-inch MacBook consisted of non-upgradable PCIe-based onboard SSDs offered in 256 GB or 512 GB capacities across all models. These SSDs provided sequential read speeds up to approximately 1,500 MB/s and write speeds up to 1,000 MB/s in the 2016 and 2017 models, representing a significant improvement over the 2015 version's roughly 700 MB/s reads and 500 MB/s writes.

Connectivity and Accessories

Ports and Charging

The 12-inch MacBook features a single port as its primary connection for charging, data transfer, video output, and peripherals, marking a significant simplification in I/O options compared to previous MacBook models. This port supports USB 3.1 Gen 1 data transfer speeds of up to 5 Gbps, allowing connectivity to USB devices via adapters or hubs. It also enables native 1.2 video output, which can drive one external display up to (5120x2880) at 60 Hz when using a compatible USB-C to DisplayPort adapter. Additionally, video adapters sold separately support VGA, , DVI, or outputs, though the port itself does not include native Thunderbolt 3 functionality. The absence of traditional ports such as an slot, Ethernet, or power connector underscores the device's ultraportable design but limits direct connectivity, often necessitating USB-C hubs or docks for multi-peripheral use or simultaneous charging and expansion. A 3.5 mm headphone jack is included for analog audio input and output, supporting speakers and high-impedance up to 150 ohms. However, for users requiring additional ports, third-party USB-C multiport adapters are essential, as the single port cannot handle charging and multiple high-bandwidth connections without such accessories. Charging is handled exclusively through the port using a compact USB-C power adapter and included USB-C charge cable. Early 2015 models ship with a 29W USB-C power adapter, providing up to 9 hours of wireless web usage on a full charge. Starting with the 2016 update, the battery increased to 41.4-watt-hour capacity for improved endurance. All models include a 29W USB-C power adapter and support USB Power Delivery (PD) for charging. The design eliminates the proprietary connector, relying instead on reversible USB-C for a more universal charging standard.

Included Accessories

The 12-inch , across its 2015, 2016, and 2017 models, shipped with a minimal set of standard accessories focused on basic charging needs. Each configuration included the MacBook itself, a USB-C charge cable measuring 2 meters in length, and a compact 29W USB-C power adapter. Apple offered an optional extended warranty program called AppleCare+ for the 12-inch MacBook, which could be purchased at the time of buying the device or within 60 days afterward. This plan extended the standard one-year limited warranty and 90-day complimentary to up to three years, adding coverage for accidental damage with a service fee per incident. To address the device's single USB-C port—which limited simultaneous charging and peripheral connectivity—Apple recommended several official adapters as complementary accessories. These included the Digital AV Multiport Adapter for video output and additional USB ports, and the to USB Adapter for connecting legacy USB-A devices. Starting with the 2017 model, Apple also endorsed hubs that provided multiple ports, such as , Ethernet, and extra USB options, to expand functionality without interrupting charging. No protective case or was included in the box, leaving users to source these separately. Third-party manufacturers like Incase offered form-fitting sleeves specifically designed for the 12-inch 's compact dimensions, providing padded protection for portability.

Software Support

macOS Compatibility

The 12-inch line, introduced in early 2015, shipped with versions of OS X and macOS tailored to each model's release. The initial Early 2015 model came pre-installed with OS X 10.10 Yosemite, while the Early 2016 update shipped with OS X 10.11 , and the Mid-2017 model with macOS 10.12 Sierra. All models received free upgrades to subsequent compatible macOS releases via Apple's Software Update mechanism, extending their software lifespan beyond initial shipment. Compatibility varied by model due to incremental hardware improvements, particularly in processor generations (Intel Core M series). The Early 2015 model supports upgrades through macOS Big Sur 11, including intermediate versions such as OS X El Capitan 10.11 (2015), macOS Sierra 10.12 (2016), High Sierra 10.13 (2017), Mojave 10.14 (2018), and Catalina 10.15 (2019).

Later macOS releases, starting with 14 (2023) and macOS Sequoia 15 (2024), dropped support for the entire 12-inch MacBook line. As of November 2025, macOS Tahoe 16 also excludes these models. Security updates for the final supported versions—Big Sur, Monterey, and Ventura—continued for several years post-release but ceased for Big Sur in November 2023, for Monterey in October 2024, and for Ventura in September 2025. As of November 2025, all security updates have ended for these versions. Within supported macOS versions, the 12-inch benefited from optimized features emphasizing its compact design and . For instance, (introduced in Catalina 10.15) enabled wireless use of the MacBook as a secondary display for compatible iPads, leveraging its high-resolution screen. Universal Control (from Monterey 12) allowed seamless cursor and keyboard sharing across multiple Apple devices, suitable for the model's portability. However, as Intel-based systems without , these machines experienced performance limitations in resource-intensive features like desktop widgets or in later updates, lacking the unified memory architecture and neural engine accelerations available in newer hardware.

Windows and Third-Party OS

The 12-inch MacBook supports installation of through Apple's Boot Camp Assistant, allowing users to dual-boot between macOS and Windows on the same hardware. Official Boot Camp compatibility extends to , with Apple providing the necessary drivers for key components such as the Force Touch trackpad, butterfly keyboard, and integrated Intel HD Graphics 5300. However, there is no native support for , as the device lacks firmware-based TPM 2.0, a mandatory requirement for Microsoft's latest operating system on Intel-based hardware. To install Windows via Boot Camp, at least 64 GB of free storage space is required on the Mac's startup disk, with Apple recommending 128 GB or more for optimal performance. The process involves downloading a 64-bit ISO file, partitioning the drive using Boot Camp Assistant, and installing Apple's Windows Support Software package, which includes drivers to ensure hardware functionality like gestures on the trackpad and integration. Once installed, users can switch between operating systems by restarting and holding the , though the low-power m processor may limit performance for demanding Windows applications. For third-party operating systems, Linux distributions such as can be run on the 12-inch MacBook either through native installation or software like Parallels Desktop or . Native installs are possible but often encounter hardware compatibility issues, including unreliable connectivity due to the BCM4350 chip and inconsistent trackpad responsiveness, requiring custom kernel modules or tweaks for partial resolution. provides a more stable alternative for lighter workloads, as it leverages macOS drivers, though it inherits the device's overall performance constraints. The 12-inch MacBook's Intel Core m-series processors, designed for efficiency rather than high performance, result in limited capabilities for both Windows and , making it suitable primarily for lightweight applications like web browsing or office productivity rather than resource-intensive tasks. Users seeking broader OS flexibility are advised to consider external peripherals or cloud-based solutions to mitigate hardware limitations.

Reception and Issues

Critical Reviews

Upon its launch in April 2015, the 12-inch received praise for its exceptional portability and design, with reviewers highlighting its slim profile and lightweight construction at just over 2 pounds and 13mm thick. The Verge described it as "beautiful" and "a thin machine with no loose pieces and no unconsidered lines," positioning it as a standout in Apple's lineup for its premium aesthetics. Similarly, noted its "amazingly thin and light" build, 24% slimmer than the 11-inch , emphasizing the groundbreaking design available in multiple colors. The also garnered acclaim for its sharpness and brightness, with a 2304-by-1440 resolution at 226 ppi that reviewers like those at The Verge said "puts the screen on the MacBook Air to shame." However, initial reviews criticized the device's performance and limited connectivity. The Intel Core M processor was seen as underpowered for its $1,299 starting price, with benchmarks comparable to a four-year-old and struggles in tasks like video or photo editing. echoed this, stating it "falls short of the and Pro" for professional workloads, despite being faster than other Core M systems. The single port drew significant complaints for requiring multiple adapters, which The Verge called "almost immediately frustrating" and a damper on portability, as no additional ports were available beyond a headphone jack. Subsequent updates in 2016 and 2017 addressed some performance concerns, earning improved review scores. The 2016 model, with faster Skylake processors, enhanced storage, and graphics, was praised by for delivering "nippier performance" that made OS X run more smoothly, alongside terrific speakers and up to 10 hours of battery life. Battery endurance remained a strength, often exceeding nine hours in light use. The 2017 refresh further boosted scores with a 1.2GHz m3 processor, better RAM options, and an upgraded butterfly keyboard mechanism for more satisfying typing, as noted by in a 4.5-out-of-5 verdict calling it "surprisingly great" for everyday tasks. CNET awarded the 2017 version 8.5 out of 10, highlighting the processor and RAM improvements for better overall speed. Persistent issues with the single port continued to frustrate reviewers, who recommended it only for users needing minimal connectivity. Aggregate professional reviews placed the 12-inch in the 8 to 8.5 out of 10 range across major outlets, reflecting strengths in design, display quality, and battery life but weaknesses in expandability and power for demanding applications.

Keyboard Controversy

The keyboard introduced in the 12-inch MacBook models from 2015 to 2017 featured a shallow key travel distance of 0.5 mm, which made it susceptible to failures caused by debris accumulation under the keys. Users commonly reported issues such as keys repeating characters, sticking, or becoming unresponsive, as small particles like dust or crumbs could easily lodge in the mechanism and interfere with its operation. These problems affected not only the 12-inch MacBook but also broader and lines produced between 2015 and 2019. Widespread user complaints led to multiple class-action lawsuits alleging design defects in the butterfly keyboard. In the United States, a significant suit was filed in , claiming Apple knew of the flaws but failed to disclose them, resulting in frequent keyboard malfunctions. Similar actions were pursued in the during 2018 and 2019, with plaintiffs arguing that the keyboard's vulnerability to everyday debris constituted a manufacturing defect. In response, Apple launched the Keyboard Service Program in June 2018, which offered free repairs for affected models, including the 12-inch MacBook, for up to four years from the original purchase date. The program initially covered single-key replacements but was expanded in 2019 to include full top case assemblies, which encompass the keyboard, trackpad, and battery, to address more severe failures more efficiently. The program ended in 2024. Apple also settled a major U.S. class-action in July 2022 for $50 million, providing compensation of up to $395 per claimant for those who had paid for prior repairs on 2015–2019 models. The controversy surrounding the butterfly keyboard contributed significantly to the discontinuation of the 12-inch MacBook in July 2019, as ongoing reliability issues damaged consumer trust and highlighted design shortcomings. In subsequent releases, such as the 2019 and models, Apple transitioned to a more reliable scissor-switch mechanism with greater key travel, effectively ending the use of the butterfly design across its laptop lineup.

Discontinuation and Legacy

Production Timeline

Apple introduced the 12-inch on March 9, 2015, with availability beginning April 10, 2015, marking the launch of a new ultra-portable lineup positioned between the and . The initial model featured M processors, a single port for all connectivity, and availability in silver, space gray, and gold colors, achieving strong initial sales as consumers embraced its thin (0.14–0.52 inches) and light (2.03 pounds) aluminum design. In April 2016, Apple quietly updated the lineup with sixth-generation m3, m5, and m7 processors, faster LPDDR3 memory at 1866 MHz, improved battery life up to 10 hours, and expanded color options to include rose gold, enhancing its appeal for style-conscious users. This refresh maintained the core design while addressing early performance critiques, contributing to sustained interest through mid-2016. The final major hardware update arrived on June 5, 2017, introducing seventh-generation m3, i5, and i7 processors, Intel HD Graphics 615, up to 50% faster SSD storage, and configurable RAM options up to 16 GB of 1866 MHz LPDDR3, alongside minor refinements to the butterfly keyboard mechanism. No further significant revisions followed, as the model entered a maintenance phase with software compatibility extending through macOS updates as detailed in related sections. Following the 2017 refresh, sales began to decline amid growing reports of reliability issues, particularly with the butterfly keyboard prone to failures from debris and wear, leading to widespread service program expansions by Apple. The lineup was ultimately discontinued on July 9, 2019, without a direct successor, as Apple shifted focus to the redesigned 13.3-inch featuring a and more versatile ports.

Post-Discontinuation Status

The 12-inch MacBook lineup was discontinued on July 9, 2019. The Early model was added to Apple's products list on June 30, 2021, and classified as obsolete on June 30, 2023. The Early model was classified as obsolete in September 2024. The 2017 model is classified as as of November 2025, eligible for limited hardware service through Apple Authorized Service Providers in most regions, though availability varies by location. Obsolete models ( and ) are no longer eligible for any official hardware repairs or parts ordering from Apple worldwide. The final major version of macOS natively supported is Sonoma (version 14), released in September 2023. It does not support macOS Sequoia (15), macOS Tahoe (26), or subsequent releases. Sonoma continues to receive security updates as of November 2025 (latest: 14.8.2, released November 3, 2025), with support expected until approximately September 2026. Third-party solutions, such as the OpenCore Legacy Patcher, enable installation of newer macOS versions like Sequoia or Tahoe on unsupported hardware, but these are unofficial, may introduce stability issues, and do not receive Apple's security patches. In 2025, used 12-inch MacBooks typically sell for $150–350 on platforms like eBay and Amazon, depending on condition, storage capacity, and model year (2015–2017), with higher values for well-preserved 2017 units due to their collectible appeal among enthusiasts seeking the unique compact form factor. In Hong Kong's second-hand market (e.g., Carousell, Facebook Marketplace), demand for the discontinued 12-inch MacBook (2015–2017 models) remains low due to its Intel processor, limited performance compared to Apple Silicon models, and the impending end of official macOS software updates. Current used prices typically range from HKD 800–3,500 depending on condition, specs (e.g., 2017 models fetch more), and storage/RAM. Market reaction is lukewarm—many listings sit unsold or sell quickly only at bargain prices. By 2026, resale value is likely near zero or collector-only as Intel Mac support ends and the device becomes unsupported. However, potential buyers face risks from battery degradation, as original lithium-polymer batteries often require replacement after years of use, and the butterfly keyboard mechanism—subject to past repair programs—remains prone to failure without official support. Environmentally, the device is eligible for free recycling through Apple's Reuse and Recycling Program at Apple Stores or via mail-in, contributing to responsible e-waste management. According to Apple's 2017 Product Environmental Report, the embodied carbon footprint for a base 12-inch MacBook (1.2GHz processor, 256GB storage) is approximately 306 kg CO2e over its lifecycle, primarily from production (87%). In August 2025, rumors suggested Apple might revive the line with a budget 12.9-inch model starting at $599, though no such product has launched as of December 2025.
