Reboot your mac. Browserstack for mac os x. Before the apple logo appears hit CMD+r. Select 'Utilities' then 'Terminal'. Type 'csrutil disable' at the command line. Then reboot normally. Place the telnet application in the /usr/bin directory. Then reenable SIP by doing the steps above but using 'csrutil enable' Working great for me now!

Will you be using the disk with another Mac? If the other Mac isn't using macOS High Sierra or later, choose Mac OS Extended (Journaled). Earlier versions of macOS don't work with APFS-formatted volumes.

1. Mac Install Telnet
2. Telnet Mac Os Terminal

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 This has probably been a good move by Apple since telnet is outdated and not a secure protocol; it shouldn't be used in general.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..

The result is nc tries to connect to the server and then immediately terminates if it succeeds. Here's an example..
nc output
If a connection cannot be established and a timeout is reached the output is like this (timeout can be controlled via the -G option i.e. -G 5)..
nc output
If a connection is refused, the output is like this..
