This document provides a detailed teardown of the 2019 16-inch MacBook Pro (Model A2141, EMC 3347). It highlights the internal layout, component identification, and repairability challenges. The device features a 16-inch Retina display (3072 x 1920), Intel Core i7 processor, 16GB RAM, 512GB SSD, and a 100Wh battery.
Tools required
- Spudger
- Suction Handle
- iFixit Opening Picks (set of 6)
- Tweezers
- T5 Torx Screwdriver
- T3 Torx Screwdriver
- T8 Torx Screwdriver
- P2 Pentalobe Screwdriver
Keyboard analysis
The 2019 model features a redesigned Magic Keyboard with a scissor switch mechanism. Unlike previous butterfly keyboards, this design does not include a dust membrane. While the keycaps are removable, the keyboard assembly itself is riveted to the chassis, making it difficult to repair or replace.
Internal components
The teardown reveals several key internal upgrades:
- Logic Board: Contains the 9th Gen Intel Core i7 processor, Micron DDR4 SDRAM, AMD Radeon Pro 5300M GPU, Samsung GDDR6 RAM, Toshiba flash storage, Apple T2 coprocessor, and Intel Thunderbolt 3 controller.
- Cooling System: Features larger fans and a redesigned heatsink that allows for 28% more airflow and higher power dissipation.
- Battery: A 100Wh (11.36 V, 8790 mAh) battery, which is the largest capacity seen in a MacBook, designed to meet FAA limits.
- Sensors: A new lid angle sensor is integrated into the left hinge, requiring calibration after repairs.
Repairability assessment
The MacBook Pro 16-inch 2019 receives a repairability score of 1 out of 10. While the trackpad is relatively easy to replace, most other components are highly integrated. The processor, RAM, and flash storage are soldered to the logic board. The keyboard, battery, and speakers are secured with glue or rivets, significantly increasing the complexity of repairs.
