@tetsuya Welcome!Before I begin answering your question,please do try to type in English,even though you do not master it.Just type what you want in
Google Translate & copy-paste the translated sentence to here.
So,basically this person is stating that his AverMedia C710 isn't detected in OBS 0.16.2.
I'm sorry to state this,but AverMedia doesn't make drivers for Macs to use,so any AverMedia products will not be detected until the company fixes this.
