iPhone Hijacking Facetime connection

Hello jdrobnsn1,

Thanks for those additional details. To stop the continuity microphone from turning on, you can change the default microphone with these steps:

1. On your Mac, choose Apple menu > System Settings, then click Sound  in the sidebar. (You may need to scroll down.)

2. Select the built in mic in the list of sound input devices.

Use your iPhone as a webcam on Mac

If you want to just completely disable the continuity function, on the iPhone go to Settings > General > AirPlay & Handoff, and turn off the Continuity Camera option.

Cheers!

Hey jdrobnsn1,

Welcome to Apple Support Communities. We understand that you're having an issue with using FaceTime on your Mac. We'd like to help.

From what you've described, it sounds like this resource can help sort out the microphone use during FaceTime calls: Control access to the microphone on Mac - Apple Support

1. Choose Apple menu  > System Settings, then click Privacy & Security  in the sidebar. (You may need to scroll down.)

2. Click Microphone.

3. Turn access to the microphone on or off for each app in the list.

If you turn off access for an app, you’re asked to turn it on again the next time that app tries to use your microphone.

Note: The Recording Indicator light in Control Center shows when your computer’s microphone is in use or has been used recently. This light increases security and privacy on your Mac by letting you know if an app has access to the microphone.

Let us know if that helps.

Cheers!

Hi jdrobnsn1,

At this point, we'd advise to contact Apple Support, so they can look into what's happening further.
