OSX energy controls redux

It's not the first time I find myself complaining about one design aspect of OSX, despite appreciating most parts of it.

This time is the Energy Control panel, which in newer versions is merged in a single slider, instead of having the usual configurations "when plugged-in" and "when battery".

Luckily there is a way to restore everything properly this time, thanks to this helpful trick (from MacRumors forum).

edit "/System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/PlugIns/X86PlatformPlugin.kext/Contents/Resources/Your-Mac-Model.plist"
find:
<key>UnifiedSleepSliderPref</key>
<true/>
replace:
<key>UnifiedSleepSliderPref</key>
<false/>

Unfortunately I couldn't find a matching model number so I just ended up editing all of them >_<
But it worked, so yay!
