So I went to Best Buy to exchange my 2015 MacBook for a 2016 one. That's above the point, however. I was just a bit sketched out by the entire return process at Best Buy. I have a few questions: 1) Do they delete all the information off the laptop? 2) The guy took me to the back to log into iCloud on one of their computers (to make sure it wasnt associated with my iCloud account anymore) I came home and changed my password, but is this usual procedure? 3) The next person to buy it shouldnt have my information, right?
