I've had a Mac Mini for 2 years and love it. It was my first non-Windows machine. I've never really DONE anything with it, though. I use my programs and that's basically it, so I'm clueless about some stuff. I just ordered a MacBook Pro, and now I'm realizing that I know so little about what I can do with a Mac, so I have a few questions: 1) My MBP will have a considerably smaller hard drive than my Mini, and I don't want to transfer all of my music (I have an enormous collection). Is there a way I can transfer just select albums and that data from my library (like playlists and play counts), as well as my iTunes settings without transferring everything? Will the play counts and playlists stay synced, or will they be different? 2) My external drive is full with my Time Machine backup(s). How can I best transfer files to the new computer? Is there a way I can transfer settings from programs like my iMessage settings, Sublime Text settings, GIMP settings and libraries, or must that all be done manually? 3) I've never had a laptop before and have always been connected by ethernet. Are there any security settings I should know about to keep it is safe as possible? I'll mostly be using it at home, but sometimes I will be using it at coding meetups, for example. I'd appreciate any help! I'm very green with all of this.
