Hi everyone, my mac just suddenly died today and I'm now planning to have it checked/repaired at one of the Apple's authorized service providers here in the metro tomorrow. So my question is: How safe are my files from being download/copied by the technician who's going to repair my mac? I have files and passwords that I don't want people to see. So what can I do to protect my files since my mac won't even start properly anymore. TIA.
