# Setup and every function.

The steps from download to a paired device, then each function in one or two lines.

## Setup

### Download and open

Open the disk image, drag AirExtend to Applications and open it. It lives in the menu bar and has no Dock icon.

### Install the audio driver, once

Click Install under Audio driver in the panel and enter the administrator password. Two devices appear on the Mac: AirExtend (output) and AirExtend Mic (input).

### Allow three permissions

Microphone, Screen Recording and Local Network. The panel shows a Permissions needed row until all three are given. Screen Recording applies after a restart of AirExtend.

### Pair a device

Scan the QR code with the phone’s camera, or open the address under it and type the six-digit code. The code changes every ten minutes and can be renewed by hand. Pair once per device.

### Choose a mode

Communicator or Broadcast, in the panel. Every device follows the Mac.

### Pick what to share

In Settings, Sources: the whole Mac or chosen apps. Chosen apps can be muted on the Mac while they stream.

## Functions

## On the other side

Functions marked “next Mac update” are built and not yet in the downloadable version.
