Hi everyone, I've searched quite a bit for a solution to this but have yet to find exactly what I'm looking for. I should mention that I'm relatively new to the Mac platform, so pardon my ignorance. On my Windows-based laptop there was a feature which would automatically adjust the screen brightness level depending on whether or not the laptop was running on AC power or on battery power (for example, 50% brightness on battery, 100% on AC). I can't seem to find any built-in way of doing this in OSX on my MacBook Pro. Can anyone suggest a 3rd party tool which may be able to accomplish this? Thanks in advance for any help.
