body: <p>I am using a mac os machine and when I installed Putty I got this error. I have installed all the required software to install Putty but it didn't work.</p>
  <p>I have installed :-</p>
  <ul>
  <li>MacPorts</li>
  <li>Homebrew</li>
  <li>Command Line Tools for Xcode</li>
  <li>Xcode (accepted the license agreement)</li>
  </ul>
  <p>I resolved this issue using another application that needs to be installed.</p>
  <p>The main problem is with X11.</p>
  <p>I installed <a href="https://www.xquartz.org/" rel="nofollow noreferrer">XQuartz</a></p>
  <p>After installation open it and go to Application on top.</p>
  <p>Click on Terminal and type putty. (command + N) - shortcut for opening terminal</p>
