Have you tried to use Telnet on MacOS only to find out it wasn’t there?You’re not alone, many have been disappointed to find out that Telnet hasbeen removed from modern versions of the system software starting fromMacOS Mojave and newer. These instructions will work for MacOS Mojave andnewer, I happen to be running Big Sur and this is what I did to get Telnetback.

Installing Telnet on MacOS with Homebrew

First I would like to mention that there is an easier route, that is usingHomebrew. I see a lot about it and many people seem happy with it but I havean aversion to putting it on my machine. If you don’t already have Homebrewon your machine, navigate over to the brew website and followthe installation instructions. I would caution against following themexactly though for security purposes. I would do it like this instead:

Multiple installations. Create a Homebrew installation wherever you extract the tarball. Whichever brew command is called is where the packages will be installed. You can use this as you see fit, e.g. A system set of libs in the default prefix and tweaked formulae for development in /homebrew.

• Homebrew (brew) is a free and open-source package manager that allows installing apps and software in macOS, depending on the user’s desire. It has been recommended for its simplicity and effectiveness in saving time and effort. Its famous description is “The missing package manager for macOS”.
• Homebrew is a package management software that simplify the installation of the softwares made for mac but it also work on linux. If you are not sure if brew is install on your mac, I recommend to checkout this stack-overflow threads.In this post, I will be focusing on how to install redis and run it at background.

Open and inspect the install.sh script to see what it does and make sure you feelcomfortable running it on your machine. And then run it.

After installing Homebrew, install Telnet

Installing Telnet on MacOS by Building Telnet from Source

This was the method I used. There are some prerequisite steps though, if youdon’t already have them you’ll need to install the MacOS command line tools.

Step 1: Installing the command line tools

Open a terminal and enter the following line, you’ll then be shown a pop upprompt.

Click install when the prompt pops up.

After that you’ll be shown a license which you’ll have to agree to in orderto install.

After that you’ll see the download progress and the install will happenafter that. Unfortunately I forgot to get screen shots of the followingmessage boxes.

Step 2: Getting the Telnet source

For this step you’ll be getting the GNU network utilitiesnavigate to the download pageand find the latest source. At the time I’m writing this it’s 1.9.4:

Step 3: Extract the source

Step 4: Configure and build

Now that the source is extracted change into the directory:

Run the configure command:

Run the make command to build:

And then install:

Either way you choose is fairly easy, the build for this is pretty straightforward and was very quick. I don’t think it even took me 10 minutes tobuild and install.
