How to mute High Sierra power chime
I keep my MacBook Pro with High Sierra plugged-in all of the time. It plays the power chime periodically, seemingly when the power reaches 100%. This drives me crazy. I want to turn the power chime sound off, but can't find a setting. Before upgrading, I used the following command in Sierra to disable it, but this command doesn't work on High Sierra: defaults write com.apple.PowerChime ChimeOnAllHardware -bool false;killall PowerChime
Is there some way to turn off the power chime in High Sierra? It would be nice to control this in Notifications like other sounds.
MacBook Pro with Retina display, macOS High Sierra (10.13.3)
