Specifically macOS. These features would be extremely useful.
Also, I noticed that when the client tries to autoupdate on macOS the process launches DropboxMacUpdater.app which in turn mounts a Volume that contains the update in a path which is randomized and attemtps to launch .dbx_installer.app
For security purposes I do not allow end users to launch applications from mounted volumes, causing them to view repeating prompts that say that they do not have permission to execute the .dbx_installer application.
As a temporary measure I have blocked DropboxMacUpdater from running, but I would like clients to autoupdate or at least manage said updates.
