Smaller volume increments in macOS
Heads up! This post was written in 2014, so it may contain information that is no longer accurate. I keep posts like this around for historical purposes and to prevent link rot, so please keep this in mind as you're reading.
Ever wish you turn the volume up or down just a tiny bit more on your Mac? Well, you can.
You already know you can increase and decrease your Mac's volume with the keyboard, but sometimes the intervals are a bit too much. I usually end up adjusting my external speakers just to get that perfect volume. But that's silly. There's a better way to fine-tune your volume without leaving the keyboard.
Simply pressing option + shift + volume up/down will result in quarter intervals, which means you can achieve that perfect volume without having to do secondary adjustments.
