hi how do you do this?
For the volume use this AppleScript:
if output muted of (get volume settings) is true then set Lautstarke to "Muted" else return "Volume: " & output volume of (get volume settings) & "%" end if
The Screen brightness is a bit more tricky, as it needs to be run either through UI Scripting (which is a pain in the and amazingly resource needing/workflow disturbing), or you'd need to install a brightness tool from Github or homebrew to be able to extract a useful value.
Or you run
do shell script "nvram backlight-level" in Apple Script once with every possible screen brightness, and add manually as a return the accurate brightness each time
The final script has to be run set in the Named & Other Triggers Section as a Menu Bar Widget.
beautiful, thank you!
