Key Features
-
Magic Keyboard with Touch ID: Full-size backlit keyboard with scissor-switch keys, Touch ID sensor, and dedicated power button — all genuine Apple OEM components.
-
Force Touch trackpad: Large haptic Force Touch trackpad with full gesture support — one of the best trackpads on any laptop, carried intact from the donor unit.
-
Complete upper chassis: Full palmrest, bottom case, speaker grilles, and structural frame — everything above the logic board in one assembly.
-
Space Grey finish: Genuine Apple anodised aluminium in Space Grey — not a colour-matched replacement, the original OEM surface.
-
Genuine Apple OEM: Pulled from a MacBook Pro 16" (2021) donor unit — not aftermarket, not third-party compatible.
-
Backlit keyboard: Full per-key backlighting with ambient light sensor compatibility, consistent key travel and tactile feel.
Repair & Refurbishment Use
This top case assembly is the go-to solution for MacBook Pro 16" (2021, A2485) repairs involving keyboard damage, liquid ingress into the upper chassis, worn or broken trackpad, or cosmetic damage to the palmrest. Because the keyboard, trackpad, and palmrest are integrated into a single bonded assembly on this model, replacing the top case is the standard professional repair path — individual key replacement is not supported by Apple's design.
The Touch ID sensor in this assembly is electronically paired to the original donor MacBook's logic board via the Apple Secure Enclave. After installation into a different A2485, the physical power button works normally, but Touch ID biometric authentication requires re-pairing by Apple. Repair shops with Apple Service Provider access can complete the pairing; otherwise the user uses a password at login. This does not affect keyboard or trackpad usability.
All keys, backlight zones, trackpad click mechanism, haptic engine, and Force Touch pressure sensitivity are verified during inspection. Aluminium surfaces are assessed for dents, deep scratches, or corrosion before grading.

Frequently Asked Questions
Will this fit a MacBook Pro 14" (2021) or MacBook Pro 16" (2023)?
No — this top case is designed exclusively for the MacBook Pro 16" (2021, model A2485). The 14" (A2442) and 2023 models use different assemblies that are not interchangeable.
Will Touch ID work after installation?
The physical Touch ID button works as a power button immediately after installation. However, Touch ID biometric authentication requires re-pairing with the logic board via Apple's diagnostics — available through Apple Authorised Service Providers. Without re-pairing, the machine uses a password at login. This is standard behaviour for any top case swap on Apple Silicon Macs.
Is this a genuine Apple part?
Yes — this is a genuine Apple OEM top case assembly pulled from a MacBook Pro 16" (2021) donor unit. It is not an aftermarket or third-party compatible part.
Does the keyboard backlight work?
Yes — the full keyboard backlight is verified as functional during our inspection. All backlight zones and ambient light sensor connections are tested before grading.
What is included in the assembly?
The assembly includes the keyboard, Force Touch trackpad with haptic engine, palmrest upper chassis, bottom case, and speaker grilles. The logic board, display assembly, battery, and I/O boards are not included.
Is shipping free?
Yes — free standard Australia-wide shipping is included with every order.
