BoxView Microphone

BoxView Microphone is a small audio driver. Once it's installed, your phone's microphone appears on the Mac as an input called BoxView Microphone, which apps on the Mac can choose like any other microphone.

#Install it (once)

You need an administrator's password on the Mac.

1. On the Mac, choose Install BoxView Microphone… from BoxView Helper's menu.
2. macOS asks for an administrator's name and password. Enter them and click OK.

The Mac's sound stops for a second or two while Core Audio restarts. The menu then reads BoxView Microphone: installed, and BoxView Microphone is listed in System Settings › Sound › Input.

#Use it

1. In BoxView, open the session controls and tap Mic under Mac sound & devices. It reads On the Mac while your phone's microphone feeds the Mac.
2. On the Mac, choose BoxView Microphone as the microphone in the app you're using.

Your phone cancels the Mac's own sound out of what it sends back, so people on a call don't hear themselves when the Mac's sound also plays on your phone.

Until it's installed, the Mic tile reads Not on Mac. The first time, iOS asks whether BoxView may use the microphone: tap Allow. If you said no, turn on Microphone for BoxView in the iPhone's Settings.

#Remove it

In Terminal on the Mac, run these two commands. The first asks for your password.

sudo rm -rf "/Library/Audio/Plug-Ins/HAL/BoxView Microphone.driver"

sudo launchctl kickstart -k system/com.apple.audio.coreaudiod
