Yes, I am using the latest version of NoMachine on this Mac.
I just reinstalled NoMachine and did not see it request microphone access at any point, it only asks to enable permissions under “accessibility” as pictured above.
I do not see the NoMachine app under microphone permissions, is there a way in which I can force the app to request microphone permission? Also, is this the reason why no audio is being streamed from the mac?
