How to change Font Smoothing in OS X

If you wish to change the font smoothing, the drop down selection is no longer available in OS X.
 
Instead, you have to delve into terminal.
 
The levels are:
Light = 1
Medium = 2
Strong = 3
 
So in terminal, type:
defaults -currentHost write -globalDomain AppleFontSmoothing -int *
 
(where * is the level you want)
 
Now refresh Finder to see the changes by typing killall Finder into terminal.
 
 
To completely disable subpixel rendering, type:
defaults write -g AppleFontSmoothing -int 0
 
Again, you have to restart the application to see it take effect (e.g. Finder as above). Map
