System Data is 330 GB on New iMac 24, why?
Why does System Data take up 1/3 the space of my storage? The iMac 24 is new and only has my photo library, which uses 320 GB, installed. The iMac 24 came with 1TB storage, but now is has only 278 GB free space. Why? Why is System Data (330 GB) using up so much space and what is it?
