Okay, so I am a total idiot when it comes to certain things like this. I am selling my 2007 MacBook and I want to get all my pictures and files off of it. I am in the process of transferring the files to my new mac now, which is long and agonizing as well, but I want to delete everything off the old laptop before I sell it. No, I do not have the original software so is there any easy way for a beginner like me to delete all of my documents?? Or can i buy some software that will do this? Any help is greatly appreciated! Thanks!
