Multiple users on one machine and Dropbox If UserA logs in to an OS X machine (at the GUI) and starts Dropbox, UserB logs in via ssh and adds a file to their Dropbox, will Dropbox work for UserB? Or does UserB need to log in via the GUI also, and then "switch" (not log out) to UserA?
DropBox does not support not-logged-in users. The solution seems to be the following:

Log in and start Dropbox from the command line:

alias dropbox='/Applications/Dropbox.app/Contents/MacOS/Dropbox &amp;'
dropbox # start it.

ps aux | grep -i dropbox # shows multiple instances running


The above technique seems to work. Error messages are sent when the second Dropbox launches:

already someone listening at socket

RegisterApplication(), FAILED TO establish the default connection to the WindowServer, _CGSDefaultConnection() is NULL.


But everything appears to work.
