Why should I allow access to the Microphone when mirroring to the TV with system audio?
To be able to mirror the screen to the TV with system audio. You should allow access to the microphone after installing Oka Mirror Audio Driver and enable audio when mirroring. It doesn't use the microphone on your Mac. It just takes the system audio of your Mac to send to TV.
If you choose "Deny" the first time, to make the sound work on TV, you should allow accessing the microphone manually:
1. Please open "System Preferences" and go to "Security & Privacy"
2. Select the "Privacy" Tab, then choose "Microphone" on the left side.
3. Check the Oka Mirror app on the right table list.
