Hello Friends, Long time reader new poster here. I recently received an offer to sell my old 2009 MB Pro. I want to wipe all my personal data. Normally I would just restore the thing and be done with it, but I have Microsoft Office installed, and I don't have the original CDs to reinstall it. What's the best way of removing personal information without reimaging the whole thing? Does Mac OS deleting really delete the file or just label it so you can write on it again? Or Is there a DBAN for Mac? I have little experience with Mac OS. Sensitive Info would be things like Passwords saved to Firefox and documents from work.
