"Use font smoothing when available" is no longer available in System Preferences / General. Text looks blurry and kinda bold on my 27" 2560x1440 screen. Especially in Safari. Anyone has a magic command line?
give it some time and you'll never want to turn it on again.
defaults write -g CGFontRenderingFontSmoothingDisabled -bool NO
Yea, logic is inverted here.
defaults -currentHost write -g AppleFontSmoothing -int 0
