Unable to connect to x3270 terminal from Mac machine

[Dhanya]

Hello Team,
On MacOS, I have both x3270 and the robotframework-mainframe3270 library loaded/installed, but the code is giving me the message "FileNotFoundError: [Errno 2]" No such file or directory: 'x3270'" 
Please see the code below:
*** Settings ***
    Library Mainframe3270
     Library String
     Library BuiltIn

*** Variables ***
     ${hostname} 10.10.101.10
     ${port} 23
***Test Cases *
Example
         Open Connection ${hostname} ${port}
          Change Wait Time 0.4 seconds
          Change Wait Time After Write 0.4 seconds

And even I tried manually to check x3270, getting command not found.

Used this command to install: brew install x3270 

and other libraries like s3270 and c3270 is working except x3270.

If someone could assist, it would be beneficial.
