We’re reaching out with an update about Dropbox on the upcoming macOS 12.3 release. For this release, Dropbox doesn’t have full support for online-only files just yet. We’re actively working on full support, and the beta version will begin rolling out in March 2022.
What you might notice after updating to macOS 12.3
Some apps on your Mac might have trouble opening Dropbox files while they’re online-only. You’ll still be able to open Dropbox files by double-clicking them in Finder.
