Using the following instructions to install Jack: https://obsproject.com/forum/resources/advanced-audio-capture-mac-os-x.142/ When I get to step 4, there is no JackRouter choice listed in System preferences/Sound/Output and select JackRouter. Do the same for input. What do you suggest I do in order to complete the installation and operation of Jack on my Mac in order to have game sounds and live commentary as I stream games. Thank you, stoicmom
