Yummy FTP Pro is an FTP client for macOS made by Yummy Software. It supports FTP/S, SFTP and WebDAV/S. It is noted for its speed and reliability, and automation capability using AppleScript.
Its programmer died in August 2018 and there seems to be no one continuing his work. As the program is 32-bit, it will fail to work starting with macOS 10.15 Catalina.
