I'm selling my old MacBook 2007 (aww) and getting a new MBP 2011 (YAY!) Well I want to know if my data is save, this is a little easy because I just replaced my old hard drive with a brand new one. But data from websites, like passwords and stuff, are they save or should I change them once the computer is out of my hands? I haven't saved any passwords on keychains or anything. In the mean time of selling it I need do to do some projects on Photoshop. If I just delete Photoshop and the files I make, is that sufficient? Thanks for you help guys!
