I recently acquired a new to me 2009 13" MBP. I want to mirror all the applications (essentially everything on the computer) from my 15" MBP to the 13". What would be the best way to do this, should I use carbon copy to mirror my computer onto the drive and pop it in the 13" or should I use a time machine backup of my 15" system on a new drive and put it in the 13"? Thanks
