Macbook Air Volume Suddenly Max

Lately, my volume would be on near 1 or 2 bars, and I start to watch a video with audio and it'll suddenly blast it at full volume. When I check, it's full bar. This happens sometimes when I open my laptop and it was originally on 1 or 2 bars. It happens even without anything plugged in. Is there a way to fix this or can someone tell me why does it do this?

Hey there cxguo,


It appears that the volume on your Mac is unexpectedly increasing while watching videos. We would love to assist you with this.


First, try force quitting the app that you are watching the video in and restarting the Mac, using these steps:




If the issue persists, try starting the Mac up in safe mode: How to use safe mode on your Mac


Also, test the sound issue in another test user account: Set up users, guests, and groups on Mac


Hope these steps help!


Take care.
