Ambient sound reduction not there under Sierra
Hi Folks,
I just upgraded to a refurbished 27" iMac and have installed macOS Sierra 10.12.5. In the sound preferences, when choosing the internal microphone for input, there used to be a checkbox for
“Use ambient noise reduction.”. This does not appear on my system. Does anybody have any advice?
Respectfully,
JC
