I didn't suggest applications that are not suited for telnet, directly. Just install telnet via homebrew. Telnet is completely insecure, so make sure you are on an isolated network connection to the host. Or, find a install Linux on it to telnet into the host.

To get the latest features and maintain the security, stability, compatibility, and performance of your Mac, it's important to keep your software up to date. Apple recommends that you always use the latest macOS that is compatible with your Mac.

Check compatibility

The version of macOS that came with your Mac is the earliest version it can use. For example, if your Mac came with macOS Big Sur, it will not accept installation of macOS Catalina or earlier.

If a macOS can't be used on your Mac, the App Store or installer will let you know. For example, it might say that it's not compatible with this device or is too old to be opened on this version of macOS. Red alert 4 free download.

When macOS High Sierra (10.13) was released, the telnet utility disappeared. This has probably been a good move by Apple since telnet is outdated and not a secure protocol; it shouldn't be used in general. However, telnet did serve a useful function - checking if it was possible to connect to a remote server on a particular port. Luckily there is a much better tool for this included in macOS - nc (netcat).
Using nc is simple and it has command line arguments that are very similar to telnet. I like to use the -vz arguments whenever I need to check if a remote server can be reached on a particular port. These arguments make nc have this behaviour..

-v Have nc give more verbose output.
-z Specifies that nc should just scan for listening daemons, without sending any data to them.
