in the past i was able to sync my Macbook desktop to dropbox automatically so anything i creat on my mac desktop will sync to a file in dropbox without me actively draging the file to dropbox (same was for my Mac native download file). This features apeears to be still working in windows but my mac intel on Sequoia 15.2 does not seem to support it. This feature was a game changer as it was like having iCloud but for people who use multiple operating systems.
