I have a MacBook Pro, running Mojave, that I take between work and home.
When at home, I plug a set of speakers into the headphone jack and play music through the speakers. In order to get a reasonable volume level on the speakers, I need to crank the volume on the Mac all the way to the top.
I forget about that volume setting when I take it to work and put on some actual headphones, and then blow my ears out with the full volume!
Is there a way to make the Mac reset to a default (reasonably low) volume for the headphones after I unplug?
