I'm following the instructions of https://gswiki.play.net/Mac_Installa...ich_(software)

I'm up to:
This should return one line that looks like * system. If you see that line, you can proceed. If not, seek assistance. If you are proceeding, then enter these commands in Terminal, one at a time, and press ENTER. Allow the system to complete the command before moving on to the next one.

rbenv install 2.6.6
rbenv global 2.6.6
ruby -v
If everything worked, the last line will return the version of Ruby that is currently active. It should look something like this: ruby 2.6.6p146 (2020-03-31 revision 67876) [x86_64-darwin19]

If you did not receive that line, or if you received a line like this: ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin20] seek assistance.

install went fine
global did nothing
ruby-v did nothing

hence received the ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin20] and it says to seek assistance.

So here i am
rbenv versions says ruby 2.6.6 but it won't let me go any further with next steps.
I am not a mac programmer just trying to follow simple instructions.

If you can help i'm resurrecting an over 20 yr old account and would love to play again, from what i have seen this addon is awesome.
