I reinstalled my OS today, on the advice of an Apple customer support person. I used the utility in recovery mode to do it. They said that it wouldn't take any extra space, but after doing so I have about 5GB less of available memory than I do before. So I figure I must have some extra operating system files on my computer taking up space. Is there a place on my machine where extra operating system files are stored so I can delete them? Thanks.
I am using macOS Sierra 10.12.16 on a MacBook Pro (Retina, 13-inch, Early 2015).
