In anticipation of replacing my 2007 MacBook Pro, I'm trying to figure out the best way to use my existing files on the new computer without transferring the entire contents of the hard drive to the new computer. I want to start fresh and only pull files from my old computer on an "as needed" basis. My existing machine has a relatively new SSD and upgraded memory. I'm thinking that I'll clone the contents of the SSD to a portable hard drive which I will attach to the new computer when I need to search for something. Anything I use, I'll keep on the new computer. The other stuff will stay archived on the ancillary hard drive. Is there a better a way to do this than what I've proposed?
