OK so I've googled around and just don't really want to take my macbook to the genius bar if I don't have to. I bought a sweet mbpro 13.3" for $290 at a pawn shop I routinely do business with. They sold it cheap cause they don't want to hassle with the firmware password issue. Do I have any other option than going to apple to get this sucker unlocked? I don't want to desolder and replace a chip either.
