First time Mac owner so not sure if I'm missing the option, but is there a way to disable brightness change when the MBP is plugged in? When plugged, the brightness goes up by a few bars from what it's set on when not on battery. I have auto brightness turned off (at least when not plugged in, forgot to check while plugged in). It's really annoying that I have to keep adjusting the brightness every time I plug, and then again when I unplug, the charger. P.S. I tried googling it, but all I got was how to change the brightness.
