In the MacOS Finder select the GO menu then choose Connect to Server (Or even simpler Command-K).

Add Server Address :

Code:

https://www.box.net/dav

At the login screen, enter Username as your full email address you used when creating your Box.net account, and the password . (Don’t worry using HTTPS creates a secure connection).

On your desktop you will now find a little drive called ‘dav’. You can now drag files on and off that drive as you would any other.
