Rezo, you don't need to do anything else. It's all pre-installed in the Teensyduino.app when you unzip it. The instructions haven't been updated for the super easy Catalina install. The main odd
thing, but doesn't really matter is the Application is called Teensyduino in the finder and info but Arduino in it's menu bar. Probably should move it to the Application folder, but it doesn't matter.
