How to remove the opaque volume dialog?

[aurora72]

Hello, I use Mojave on a MacBook Late 2009. When I'm watching Youtube videos, I adjust the volume quite often.

Mojave's got a big opaque volume dialog which distracts the video. (screenshot)

Is there a way to remove that volume dialog?

There is no simple setting.
Without modifying system files, this seems to be the easiest way:

How do I disable the volume control overlay?

When changing the volume on a Mac, you get a big ugly gray bezel showing the change in volume. This is super annoying when (say) watching a movie. Is there any way to disable this?

In automator, create a new service that takes no input. Give it a single action: Run AppleScript Enter the following AppleScript:

set x to get output volume of (get volume settings)
if x > 10 then
set volume output volume (x-10)
else
set volume output volume 0
end if

Save the service with the name "Volume down", and bind the service to F11.
