Just got a apple certified refurbished 2015 rMBP and loving it. it came with el capitan. I want to do a clean install of sierra. How do i backup the apps that came with my mac? (imovie, pages, numbers, etc etc) Coming from using windows my whole life, app installations in windows is more complicated and you cant simply always drag an app folder to a hard drive to back it up but so far with macOS, the apps just seem to sit in the application folder, there is no hidden files. Do i simply drag all the apps i want to backup from the application folder to a backup location and drag them back into application folder after a fresh install? or is there more to it?
