New 12-Inch MacBook Teardown Reveals Tweaked USB-C Hardware and Tamper-Evident Screws

iFixit has completed an in-depth hardware teardown of the new 12-inch Retina MacBook that Reveals only mi**r under-the-hood changes to Apple's ultra-slim **tebook compared to the 2015 model.


Specifically, Apple has slightly Tweaked the **tebook's USB-C Hardware by permanently affixing the cable to the USB board. The new arrangement is **t compatible with the original 12-Inch MacBook.

Apple has also switched from using a tri-wing screw to a repair-friendly Phillips screw, but the **tebook's Torx hinge Screws are filled with a Tamper-Evident substance that disintegrates when you insert a screwdriver.


iFixit confirmed that the slightly-longer-lasting 41.4-watt-hour battery in the 12-Inch MacBook is **t visually distinguishable compared to the 39.7-watt-hour battery in the 2015 model, suggesting improved battery chemistry.

The logic board and other internal components yielded ** significant surprises, while the **tebook's exterior looks virtually the same beyond a new Rose Gold color finish and an updated EMC number of 2991.

iFixit lists the new 12-Inch MacBook's logic board chips as follows:

- Intel SR2EN Intel Core m3-6Y30 Processor (4M Cache, Up to 2.2GHz)
- Toshiba TH58TFT0DFKLAVF 128 GB MLC NAND Flash (x2, 256GB Total)
- Micron MT41K256M16LY-107 4Gb DDR3L SDRAM
- Universal Scientific Industrial 339S0250 Wi-Fi Module
- Broadcom BCM15700A2

- Texas Instruments CD3215B01 61AHXHW
- Intersil 95828


The new 12-Inch MacBook retained a repairability score of 1 out of 10, which is the lowest score possible, as the processor, RAM, and flash storage are still soldered to the logic board, and the battery remains entirely glued into the lower case.
