The starting "bong"—Sometimes I hear, sometimes not
Hi
Is there a way to turn on/off the bong sound when starting up my MacBook Pro?
For as long as I've had it, when starting up my mid 2015 MBP, sometimes I hear the "bong" sound, then for a while, without knowing why, I won't hear it.
The change from on to off, or off to on, seems to happen for no reason, tho I wonder if I have somehow accidentally hit the keyboard shortcut that toggles it on/off, if that shortcut exists.
