I'm trying to completely wipe my MBA 13'' (the latest model), and am wondering besides just reinstalling Lion on it, the safer route would be. I plan on selling this and granted I don't have sensitive info, I just want to be on the safe side. With my old Macbook Pro's, I just 7-layer wiped it, but with these SSD's I understand that things aren't that simple anymore. Being completely technical-illiterate, how should I go about doing this? I did a search and read about encrypting, but the whole thing sounds very complicated and confusing. Not really sure on how to begin this... Comments and suggestions appreciated. Thanks!
