Smaller volume increments in macOS

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.
