Your Mac’s sound comes out of the tablet speakers, and each tablet shows up as its own output device in macOS. This page explains why that needs a small audio driver, and what happens while it installs.
A connected tablet appears as a separate output device in the macOS Sound menu. Sending sound there, taking it back and setting the level all happen from the menu bar or the keyboard keys as usual — there is no separate audio panel of ours to learn.
Your choice is remembered: because each tablet has its own device identity, reconnecting the same tablet routes the sound back to it on its own. The device also stays in the menu when the tablet goes to the background — the speaker belongs to the connection, not to being in the foreground.
On macOS, sound can only reach another device if that device appears as an output device in the system. Without one, the sound indicator still says “MacBook Speakers”, and the volume keys and device selection never reach the tablet.
The driver ships inside the app — there is nothing extra to download, and it carries the same signature Apple notarized. The administrator password, though, is unavoidable: macOS loads audio plug-ins only from a system folder, and there is no way to write there without authorization.
When you want audio on the tablet, the app shows a bar — nothing is installed on its own.
If you accept, the administrator password is asked; it is not asked again on later connections. Only an app update that also refreshes the driver asks for it once more.
⚠️ During the install all audio on the Mac cuts out for a moment, because the macOS audio service restarts. Do not do it in the middle of a meeting or a call.
The driver is needed only to send audio to the tablet. Skip it and the screen, the controls, the pen and everything else work exactly the same; sound keeps coming from the Mac’s own speakers.
The audio driver is optional; nothing is installed unless you ask for it.
