I have a 2012 13" MacBook Pro. However the volume at its highest setting is still not loud enough in many scenarios.
I set the volume to highest in System Preferences. VLC gives me a way to increase the volume over 100% but I want to make the change across the system.
Can someone tell me how to make this change?

http://froyosoft.com/soundbooster.php. Soundbooster comes as lite free version and paid version in App Store (currently around 7 EUR). Does what it say. You set boost once (system-wide), then your volume control works normally, but louder. It is nice to the processor, uses only 2% on my 2011 MBP You have also EQ there and selective volume, but works simple enough to just enable boost and forget. No noticeable quality loss
