The gold standard of macOS file transfer apps just drove into the future.
There are many different FTP clients for macOS, some are better than others, and I'm glad about Transmit, which is an FTP program where you can save your users, group them in folders and connect across hosts and systems.
In fact, I would say that Transmit is more than just an FTP program, it can be much more than what I associate with a normal FTP program such as FileZilla which is also a really good FTP program you can transmit to your Amazon S3 if it Is necessary and many other things.
So, are you looking for an FTP application that is more than just connecting to ports 22 and 21? Then you definitely have to take a look at Transmit.
