KB01902: How to enable Telnet on macOS High Sierra - Big Sur

Telnet is no longer included with macOS starting in High Sierra. Telnet is still a widely used technology in the AV industry and is helpful for troubleshooting Atlona products.

There are a few ways to get telnet on macOS:

1.) You can run Windows in a VM like VMWare Fusion or Parallels. This would allow you to use the wide variety of terminal emulators like Putty, Hercules, or TeraTerm.

2.) Re-install telnet using Homebrew:

  • Install Homebrew on macOS using terminal: /usr/bin/ruby -e "$(curl -fsSL"
  • Use Homebrew to install telnet: brew install telnet
  • Run telnet: telnet device-ip-address

3.) Use a stand-alone terminal emulator such as ZOC:

  • Note: ZOC comes with a 30-day free trial and then it must be purchased.
