Downloading MacSFTP 1.0 for Mac from our website was free. The application lies within Internet & Network Tools, more precisely General. This Mac application was originally designed by Jean-Pierre Stierlin.
From the developer:
MacSFTP is the only SFTP (Secure File-Transfer over SSH) client for MacOS 8.1 up to X. It features an easy to use drag & drop interface, SSH1 and SSH2 protocols support, and uploads MUCH faster than MacOSX 10.1.2 built-in command line sftp client.
