Hello, I am considering selling my early 2011 13' MBP and buying a 15' rMBP for law school. I did a quick search on the forums here, but wasn't able to come across a quick guide about how I should go about getting my MBP ready to sell. I am mainly concerned with getting my apple ID off of the machine, and backing up all of my information so that when I get the new laptop I can transfer all of my settings/programs over with ease. So how do I go about making such a back up? How can I be sure that the person I sell the laptop to won't be able to access any of my information? Should I wipe the hard drive and reinstall OSX (but isn't OSX associated with my Apple ID?)? Sorry if this has been asked a million times before, but I couldn't come across anything and this seems like a topic that has a guide out there somewhere. Thanks.
