        Sure, macOS has ssh built it, just run the command @Clyde suggested from a terminal window.

            @chaska04 With successful you don't mean a working connection, I presume? Because the connection seems to have been closed right after the start of the key exchange. Normally the debug1: SSH2_MSG_KEXINIT sent is followed by a debug1: SSH2_MSG_KEXINIT received and more messages about the key exchange.

            Can you read the log file /var/log/auth.log from Retropie and show us the lines with timestamps that correspond with your connection attempt?

            Does ssh show more than

            debug1: SSH2_MSG_KEXINIT sent
            Connection closed by <MyIp> port 22
            

            if used with -vv or -vvv?

            By the way, I'm not an expert in ssh or networking, I'm just trying to collect more information for people who are. So if anyone here with more knowledge wants to step in, be welcome. :)

              When I meant successful I was referencing to when it didn't work on my PC. Because Termin Doesn't have SSH built in!

                @chaska04 I thought as much, but it's better to know for sure. You can display the contents of /var/log/auth.log with this command on the Retropie terminal console:

                cat /var/log/auth.log

                  @clyde When I run this command it displays a long output which is impossible to manually copy. Is there a certain part I should Copy.

                        @chaska04 You ssh server on the retropie is broken - how did you install the system ?
                        Try reinstalling ssh on the retropie:

                        sudo apt-get install --reinstall openssh-server

                          @mitu I installed it with an image from retropie website. In late 2017. Trying the command now.

                            @chaska04 Sorry, No Luck. I ran the command and re-installed then rebooted.

                              @chaska04 Then try a complete uninstall then install again

                              dpkg -P openssh-server
                              apt-get install -y openssh-server

                                        @chaska04 What's the actual error and when does it occur - during the uninstall or the install ?
