Tel-FTP for macOS High Sierra has been released

WinOnMacs released Telnet FTP for MacOS High Sierra today. Tel-FTP is our initial release, we now have full support for macOS High Sierra.

About FTP

The File Transfer Protocol (FTP) is a standard network protocol used for the transfer of computer files between a client and server on a computer network.

FTP is built on a client-server model architecture and uses separate control and data connections between the client and the server.[1] FTP users may authenticate themselves with a clear-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it.

About Telnet

Telnet is a protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. User data is interspersed in-band with Telnet control information in an 8-bit byte oriented data connection over the Transmission Control Protocol (TCP).

Supported Protocols:

  • Telnet
  • FTP

About WinOnMacs:

There is a multitude of software developed only for the Windows operating system and even when software vendors port their applications to another platform, generally it lacks features that the Windows version contains. The only solution these developers face is to have access to both systems for testing which leads to increased infrastructure demands, and wasted project resources. Our goal is to have native ports of essential Windows tools and applications made available for MacOS users.

Version 1.0.0 New Features:

  • Native FTP Support
  • Native Telnet Support

We now use FastSpring as our preferred storefront, you can pay with Credit / Debit Cards, PayPal, Amazon payments, Wire Transfer etc. etc. This store is very secure, simple and fast.


Putty brings Telnet and FTP support back to macOS High Sierra

With the release of macOS 10.13 High Sierra Apple has decided to remove basic Telnet and FTP support from their flagship operating system, mainly due to security concerns. While reading over some forum post I came across post like this one.

“Apple in all their “infinite” wisdom has decided to remove Telnet and FTP from their command line tools. Now this is so brain dead, I can’t believe it! I read a few forums where people were like, “Well use SSH and SFTP instead. Telnet is not secure.” Who the F**K are you to tell me what tool to use? I work with devices every day that have nothing but telnet and don’t have SSH on them! Apple has basically decided to screw developers and cripple their Unix.”

Well it’s not the end of the world you know, their are other solutions to bring these basic tools back to your Mac. One of the easiest and simplest solutions is to spend $15.00 and purchase a PuTTY for Mac license. PuTTY has support for SSH, FTP, SFTP, Telnet, rlogin and more.

Purchase Putty 8.7.0 now and have Telnet SSH FTP SCP on your Mac made easy!

I know it is not optimal and hopefully we will be able to support resizing sometime in the future.
