One of the biggest ones from past days was media files and especially photos. They are large, users like to arrange/rearrange, compress, and manually back them up (or “back them up” depending on the knowledge level of the user). They are also rarely modified after being initially tweaked. And on the other side: Apple computers typically don’t have upgradeable hard drives so for anyone who takes photos/video it’s an inevitable countdown to zero free space.
