Wiping the hard drive of a broken mac Hi all, I have a 15" mac book pro that I want to sell for parts. The computer is totally broken and does not function at all. I need to wipe the hard drive because I think some of my personal information is still on it. Is there a way to do this? I can't see the screen at all. Some keyboard functions may still work, but not very likely. Any help appreciated! I'm computer illiterate so sorry if this doesn't make much sense.
