hard drive space is low
My MacAir says "Dropbox can't sync until you free some disk space on your computer" I have deleted photos and videos, many docs, emptied trash. The 'about this Mac' storage window says I have 2.28 GB available of 121.12 GB. Documents are taking up 57.78 GB, Mail 15.83 GB, Apps 8.23 GB, system 11.08 GB, Other 20.71 GB.
I think I don't want to sync with Dropbox anymore. I don't know what to do next.
MacBook Air 13″, macOS 10.15
