OSX High Sierra telnet crash Abort trap: 6
Already have the answer, just IDNK why can't replay in the original post, here is the solution:
just do this in a terminal window:
$ brew unlink inetutils
and then this one
$ brew install telnet
it will reinstall patched version of telnet for High Sierra
Hope this works for everyone, it did it for me.
