Hello, I want to give my old MacBook to my gf, and while at it, I want to put in an SSD, too. I want to keep some applications, but otherwise I want it to be like a clean-install. So I prepared a new user, cleaned up my old one, and now, ready to delete that one, I want to copy Macintosh HD to the new SSD. What are some files I can delete apart from my old user files? Is there away to reset library files, crash files etc. but keep the applications? Thanks alot in advantage!
