In Mac OS X, connection can directly be made to a remote FTP (File Transfer Protocol) server, from within the OS, without using any additional software.
The easiest way is to open the Finder Window and select the from the main menu Go -> connect to Server. A dialog box will appear. Enter the server name (including ftp://) and click connect.
You can then login either as a guest user or enter username/password for registered accounts.
Alternatively, you can type the ftp server name in the Safari’s address bar for quick access to the built-in FTP client.
The downside of this simple method is that it can only be used for downloading files. Moreover, if the user name/password consists of the symbol ‘@‘ then, well, Finder fails to connect!
