    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.

    Yes, you can disable it in the energy settings in the system preferences.

    Specifically, there's a checkbox on the battery tab of the Energy Saver preference pane in System Preferences (found under the Apple logo menu) to toggle this effect.

    If you're using your non-admin account (you use a non-admin account for regular use of course, for extra security), you'll have to click the padlock icon to unlock and then enter your admin login/password in order to change this setting.
