Boardview for an Apple MacBook main logic board under the M42B and M42C project codes, PG1/PG3 version, with board reference 051-7173, marked as a DVT (design validation test) stage layout. The file comes in a 195 KB RAR archive. Because DVT boards are pre-production, small layout differences from retail units are possible, so compare component positions with your PCB. A boardview viewer such as OpenBoardView lets you find parts, nets and test points when tracing power and signal faults.
