About this part
The Cowling, TIO Flex Cable to Logic Board (Apple part number 923-03428) is a genuine Apple part that fits the Mac Pro (2019) and Mac Pro M2 Ultra 2023. This cowling is the small metal cover that secures the TIO flex cable to Logic Board 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: MacPro7,1 and MacPro14,8.
Signs the cowling needs replacing
- The cowling went missing after a previous repair
