How do I stop my MacBook for automatically turning sound volume down in System Preferences.
My volume on my MacBook Pro is very low. I have it turned up all the way. I go into system preferences and the volume there is very low (about ⅓ of the way up). I turn it up and the next day it is back to the low setting again. How do I stop this from happening?
MacBook Pro 15″, macOS 10.13
