Transmit is an excellent FTP (file transfer protocol), SFTP, S3 (Amazon.com file hosting) and iDisk/WebDAV client that allows you to upload, download, and delete files over the internet. With the most Mac-like interface available, Transmit makes FTP as simple, fun, and easy as it can possibly be.

Compatibility: OS X 10.11 or later 64-bit
