On Mojave macOS, Finder here says that I am using 72 gigs of space.
But when I open my HD it all adds up to about 42 gigs. Which is size of the system folder as shown in About This Mac, however, here the system folder holds 10 gigs.
Here's what it shows when I press manage in about this mac> storage.
So how should I fix this? I don't even have 72 gigs worth of stuff on my mac to begin with. Time machine has also been disabled so there are no time machine backups at the moment.
