Product Overview

Don't gamble your client's MacBook on cheap, aftermarket knockoffs. Designed specifically for the 2021 MacBook Pro 16-inch (A2485), this is a 100% Genuine Apple OEM Logic Board, pulled from a working unit and verified by our micro-soldering experts.

Powered by the revolutionary M1 Pro chip, this complete assembly restores peak factory performance to dead or liquid-damaged 16-inch MacBooks.

Available Configurations:

Frequently Asked Questions 

Q: Is the Touch ID sensor strictly required to use this logic board?

 A: Yes. Apple ties the Touch ID sensor directly to the M1 Pro's Secure Enclave. If you install a logic board without its originally paired Touch ID button (which we include), the Mac will boot, but the fingerprint scanner will be permanently disabled, and Apple Pay will not function.

Q: Are these boards locked to an MDM profile or Apple ID?

 A: Never. We run a strict serial number check and DFU restore on every single board. They are guaranteed to be clear of Activation Locks, iCloud accounts, and corporate MDM profiles.

Q: Do I need specialized software (like Apple Configurator) to install this board?

 A: Once physically installed, you may need to run a DFU "Revive" or "Restore" via Apple Configurator 2 using a second Mac to pair the board to the new display and top case, which is standard procedure for Apple Silicon (M-Series) logic board replacements.

Q: How does the defective board Buyback Policy work logistically?

A: If you select the Buyback variant, you receive the discounted price upfront. We will ship you the working logic board. Once you complete your repair, simply pack your old, defective A2485 board into the same box and contact our support team to arrange the reverse pickup.

Q: Will this 820-02100 board fit the 14-inch A2442 model?

 A: No. While they share the same M1 Pro chip, the chassis architecture and thermal module standoffs are different. This board is exclusively for the 16-inch A2485.
