About this MacBook

This version of the MacBook has been fully redesigned with the MacBook 2015 models. In 2015 Apple’s focus was to create a powerful internal capacity, but using lighter and thinner models.

Another change that was made from previous MacBook models is that the connectivity options for external devices were reduced to 2-USB-C ports including a headphone jack. The MacBook 12 Inch computer with a 1.2 GHz Intel Core M processor (M-5Y51) continues to remain a customer favorite to this day. Further specifications and capabilities for this device can be found below.

This device has 8 GB of RAM and 512 GB of onboard PCIe-based flash storage (cannot be upgraded). The thickness of this device was drastically reduced to between 0.14 – 0.52 inches and the weight decreased to 2.03lbs. This MacBook is thinner and lighter than the MacBook Air series. This MacBook came with macOS 10.10.2 and could be updated to macOS 11.

Storage

The storage includes a 512 GB of PCIe-based flash storage soldered to the mother board (unable to be upgraded). The storage speed of the hard drive is estimated between 451.7 – 738.2 MB per second.

Screen Size and Resolution

This MacBook came with a 12-inch screen that incorporates an upgraded resolution of 2304×1440 and a new TFT LED-Backlit active-matrix “Retina” display. This allows for millions of colors to be displayed clearly because the pixel density is 226 pixels per inch. This higher pixel density ensures that individual pixels are not easily detectable at a normal viewing distance. This device utilizes IPS technology with the ability to support other resolutions such as: 1440×900, 1280×800 and 1024×640.

Processor& Graphics Processing Unit (GPU)

The pre-installed operating system on this device was MacOS X 10.10.2 (14C2061). Apple also made a return to Intel for the provision of a graphics processor with the Intel Integrated HD Graphics 5300 graphics processor replacing the NVIDIA GeForce that was used in the last 2010 model. This processor shared the memory of the onboard 8 GB 1600 MHz LPDDR3 SDRAM.

Memory & Architecture

This devicewas powered with a 4 MB Level 3 cache and 8 GB of onboard 1600 MHz LPDDR3 SDRAM (cannot be upgraded). This is centered around a 64-Bit architecture.

Battery Life

As a result of Apple’s innovative new-terraced design packing of battery cells this device includes39.7 -watt-hour lithium polymer battery that guarantees 10 hours of battery life.

Available Upgrades

This device has 8 GB of RAM and 512 GB of onboard PCIe-based flash storage (cannot be upgraded). The thickness of this device was drastically reduced to between 0.14 – 0.52 inches and the weight decreased to 2.03lbs. This MacBook is thinner and lighter than the MacBook Air series.

Common questions

Is MF865LL/A the same as A1534?

Not exactly. MF865LL/A usually points to a specific retail configuration, while A1534 identifies the broader Apple hardware family. Always check the EMC and model identifier too.

What MacBook is model A1534?

A1534 is the Apple A-number shown for this MacBook family. Use the order number, EMC, and model identifier on this page to narrow the exact configuration.

What does EMC 2746 mean?

The EMC number is another Apple hardware identifier. It helps separate closely related models that may share a similar name, year, or A-number.

Can the RAM or SSD be upgraded?

Check the spec table for the exact configuration. Many newer Apple Silicon Macs have memory and storage integrated into the board, so RAM and SSD upgrades are often not practical after purchase.

What macOS versions work with this model?

Use the model identifier, release year, and processor family from the spec table when checking macOS compatibility. Compatibility can change as Apple releases new macOS versions.

Is this MacBook still worth buying used?

It can be, depending on price, battery health, memory, storage, and condition. Compare this exact order number and model identifier against similar Techable listings before buying.

How much is this MacBook worth?

Value depends on RAM, storage, battery health, cosmetic condition, accessories, and market demand. Use the SellMac path on this page for a quote or use the identifiers here when comparing resale prices.

What should I search if this page is not the exact configuration?

Search the order number first when available, then compare the A-number, EMC, model identifier, year, chip, RAM, and storage. The same A-number can cover more than one configuration.
