Use a T4 Torx screwdriver to remove the two 15.5 mm‑long screws securing the outer edge of the I/O board.

Use a T6 Torx screwdriver to remove the two 20 mm‑long screws securing the inner edge of the I/O board.

Partially tighten the four screws securing the board.

Lay your Mac Studio down and plug a cable into one of the ports to ensure proper fit and alignment, adjusting the port as necessary—the cable should be easy to insert and remove.

With the cable plugged in and the board in position, fully tighten all four screws.

Unplug all cables before continuing.
