About this part
The Ethernet Board Connector Cowling Screw (5 Pieces) (Apple part number 923-12506) is a genuine Apple part that fits the Mac Studio M3 Ultra 2025 and Mac Studio M4 2025. This cowling is the small metal cover that secures the Ethernet Board connector Screw (5 Pieces) connection. Its job is to keep that connector seated and shielded inside the case. Match the cowling and its mounting hardware to the listed device model.
Before you order, match the model identifier on your Mac (Apple menu, About This Mac, System Report) to one of the identifiers listed for this part: Mac15,14 and Mac16,9.
Signs the cowling needs replacing
- The cowling went missing after a previous repair
- A bent cowling that no longer sits flat
- A connector underneath that keeps working loose
- A component that cuts out after the bottom case was opened
