The following steps have been tested on OS X El Capitan.
1. Install Xcode
2. Install Command Line Tools
Launch the terminal, found in /Applications/Utilities , type this command :
xcode-select –install
3.Download and install MacPorts
4.sudo port -v selfupdate
5. type this command sudo port install putty
6. Type Putty into terminal
7. create a shortcut cp /opt/local/bin/putty ~/Desktop/PuTTY

TIP: “sudo port install putty”… this will take a long time if you are installing it for the first time…. and make sure you are connected to the internet

For the 4th step it doesn’t say where to type “sudo port -v selfupdate”. Can some one tell me what to do at this step?
LikeLiked by 1 person
In steps 4 onward, you type those commands into the terminal mentioned in step 2, found in Applications > Utilities folder.
However, some people report this process works better if you have closed and re-opened the terminal after the MacPorts step in step 3.

You need to reboot the terminal….i spent half a day trying to figure out why port command is not working…after reboot, it worked

Yes, quit the Terminal application and restart it. It shouldn’t be necessary to restart your computer–only the Terminal app. Then the port command should work.

open a terminal, then write:

I am also on Sierra and it is telling me it can not open display. It did prompt me for python and python2 which I chose 2 after looking them up. Did it prompt you for these things? I just find it strange to not work for me but work for you and thought maybe you could give some insight.

Installing XQuartz is sufficient to run PUTTY on MacOS. Once XQuartz is installed, launch the application. Right-click on the X icon and go to “Applications” and select “terminal”. Once you open terminal, you can launch the putty application by just “putty” command. Tried and Tested this.

FYI…With OSX 10.15.6 Catalina OS, Putty works perfectly okay by simply following the instructions.
just simple 3 pieces to it
Xcode from the App Store
Command_Line_Tools_for_Xcode_11.5.dmg
XQuartz-2.7.11.dmg
+ the following commands
sudo port -v selfupdate
sudo port install putty
[RESTART]
