In Order to make sure central works , if you are familia with OSX terminal and typing CLI commands , while Central ia on you can open terminal and type:
tail -F /Users/[USER_NAME]/Library/Application\ Support/Waves\ Audio/Waves\ Central/Logs/wlc.log
> Make sure that [USER_NAME] is the current user name.
you can see Central log being written in real time , and in case you see the word “Peer_closed” you can understand that something is wrong in the connection and you need to close/reopen it.
And While central works you will see text jumping much like in the Matrix movie
