My cat walked on my keyboard/mouse/touchbar and now my volume is too low. It happens with both headphones and using the internal speakers. I've looked at Audio/Midi settings and everything seems okay there, but testing still plays the audio too quiet.

What kind of secret "low volume" setting did my cat engage and how do I reverse it?

I just solved my own problem with an NVRAM/SMC/PRAM reset. The world may never come to understand what secret Mac fu cats possess.

  • This answer still works as of today. No sound, low volume, .... why Apple never gets this right? Nov 10, 2020 at 18:15

In my case, I don't want to restart the computer. A simple sudo pkill -9 coreaudiod did the trick for me. You can also try this command if your mac has no sound.

  • Quick and easy solution here. Thanks :)
