Alternative Ways to Control The Volume Level Of My Mac In OS X?
- Use the volume keys on your keyboard (hold Shift + Option for finer control)
- Go to the Sound pane of System Preferences
You mentioned alternate ways to control the volume. Here is one from the terminal:
sudo osascript -e "set Volume 5"
You can change to "5" to a higher or lower number to make the volume go up and down in intensity.
sudo osascript -e "set Volume 0.1"
This will put your volume at super quiet
As @Tortilla stated, for finer control without the terminal, you can hold Shift + Option while using the F11 or F12 keys to adjust the volume by 1/4 (0.25) increments.
