Hello all. I'm new to the Mac world, just picked up at 13" rMBP. Two questions: 1) In finder, I have a folder for documents on the left side, but no locations for pictures or videos. Any help? 2) I'm trying to use migration assistant to transfer my files, but it isn't recognizing my Seagate external hard drive. I'm transferring from Windows 7 if that helps. Thanks in advance!
