Apple Resources - New Mac Clean Installation

New Mac Clean Installation

  When you do a clean installation, you let macOS run its
  Setup Assistant and create a new, empty user account. During
  the process, you enter some information, such as your Apple
  ID, so your iCloud account is activated, but, for the most
  part, your Mac will be a tabula rasa-a blank slate. It will
  contain the default apps that are part of macOS, but nothing

  If you go this route, you then must manually copy files from
  your old Mac, or from a backup. This part of the process can
  be time-consuming, but it can allow you to sift through your
  files to find what you really need, and slim down your Mac.
  When you do this, you may be surprised to find how much you
  can ignore from your old Mac.
  Your Home Folder: you want to copy most of the files from
  your home folder (that's the folder with the house icon and
  your username). You don't want to copy the folders at the
  top level of your home folder-Desktop, Documents, Downloads,
  Movies, Music, and Pictures-but rather the contents of these
  folders into the identically-named folders on the new Mac.
  Again, take this opportunity to check whether you need to
  keep all of the files in these folders.
