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.
I have installed :-
- MacPorts
- Homebrew
- Command Line Tools for Xcode
- Xcode (accepted the license agreement)
I resolved this issue using another application that needs to be installed.
The main problem is with X11.
I installed XQuartz
After installation open it and go to Application on top.
Click on Terminal and type putty. (command + N) - shortcut for opening terminal
