just bought the latest MacBook Pro, 15 in, and trying to find best way to copy over the stuff i want. Using wireless network, it started copying over Everything and i had to abort. The point of new computer was clearing out the junk (plus was slow). How best to copy only files and folders i want? Also, iMessage did not update and give me all my messages. Or apple mail. Or iBooks. And i did check my iCloud settings. What am i missing?
