Cowling, Antenna Coaxial Cable, (5 Pieces)

About this part

The Cowling, Antenna Coaxial Cable, (5 Pieces) (Apple part number 923-12518) is a genuine Apple part that fits the Mac Studio M4 2025. This cowling is the small metal cover that clamps the Antenna Coaxial cable, (5 Pieces) connector to the logic board. That connector links the logic board to the antennas in the display hinge or housing. If it is missing or bent, the connector can lift slightly and the Wi-Fi and Bluetooth can become unreliable.

Before you order, match the model identifier on your Mac (Apple menu, About This Mac, System Report) to the identifier listed for this part: Mac16,9.

Signs the cowling needs replacing

• Wi-Fi shows weak bars even next to the router
• Bluetooth mice or headphones drop out or will not pair
• "No hardware installed" for Wi-Fi after the case was opened
• Signal that changes when the lid angle changes
