Apple MacBook Pro 16" 2021 M1 Max Logic Board — Genuine OEM Replacement
A genuine Apple logic board pulled from a MacBook Pro 16" (2021, model A2485), featuring the M1 Max SoC with 10-core CPU, 24-core GPU, and 32GB unified memory integrated on-chip — plus a 1TB NVMe SSD soldered to the board. Professionally tested and graded by Reboot IT before dispatch. Backed by a 12-month warranty and free standard AU shipping.
Key Features
-
Apple M1 Max SoC — 10-core CPU: 8 performance cores + 2 efficiency cores, up to 3.2GHz — Apple Silicon's fastest single-core performance in the 2021 MBP generation.
-
24-core GPU integrated on-chip: Pro-grade GPU delivering extraordinary graphics throughput; supports up to four Thunderbolt displays simultaneously.
-
32GB unified memory — on-chip: High-bandwidth 400GB/s memory shared between CPU and GPU; soldered into the M1 Max die — not removable.
-
1TB NVMe SSD — soldered: Fast PCIe Gen 4 NVMe storage soldered directly to the logic board, transferred intact from the donor unit.
-
Full I/O controller suite: Three Thunderbolt 4 (USB4) ports, HDMI 2.1 controller, SD card controller, MagSafe 3, and headphone jack interface — all on-board.
-
Genuine Apple OEM: Pulled from a screen-damaged donor unit with fully functional board — not aftermarket, not a third-party compatible clone.
Repair & Refurbishment Use
This board is sourced from a MacBook Pro 16" (2021) donor unit where the display assembly was damaged but the logic board remained fully functional. It's the highest-value harvestable component from this generation — combining M1 Max compute, 32GB memory, and 1TB storage all on a single unit. For repair shops, ITAD operators, and experienced technicians, this is a proven path to restoring a screen-damaged or liquid-damaged 16" MBP to full working condition.
After installation, the system delivers Apple's flagship 2021 laptop performance: professional-grade ProRes acceleration, sustained CPU performance under load, and exceptional power efficiency. The M1 Max sustains 30W under extended compute without thermal throttling — a key advantage over Intel predecessors. Final post-install testing should verify all Thunderbolt ports, HDMI controller, Wi-Fi module connections, and battery management via the power connector.
Both the unified memory (32GB) and NVMe (1TB) are permanently attached to this board and transfer with it. There is no standalone SSD blade or RAM module to handle separately.

Frequently Asked Questions
Will this board fit a MacBook Pro 14" (2021)?
No — the 14" (A2442) and 16" (A2485) use different logic board form factors and thermal assemblies. This board fits the 16" model only.
Can I upgrade the RAM or SSD after installation?
No — the 32GB unified memory is integrated inside the M1 Max SoC and cannot be removed or upgraded. The 1TB NVMe is soldered directly to the board. Both transfer with the board as purchased.
Is this a genuine Apple part or a third-party clone?
This is a genuine Apple OEM logic board pulled from a screen-damaged MacBook Pro 16" donor unit. It is not an aftermarket or third-party compatible board.
What has been tested on this board?
Reboot IT tests CPU and GPU function, memory stability, all three Thunderbolt 4 ports, HDMI 2.1 controller, MagSafe power controller, Wi-Fi and Bluetooth antenna connections, SD card reader, and SSD read/write speeds before grading.
What's the difference between the 24-core and 32-core GPU M1 Max?
Apple offered the M1 Max in two GPU configurations: 24-core and 32-core. This board has the 24-core GPU variant. Both use the same 10-core CPU and 32GB unified memory; only the GPU core count differs. For most repair and resale purposes the performance difference is modest.
