How can I enable Trackpad tap-to-click for the login window in OS X 10.8? In older OS X versions, this used to work just fine:

defaults write /Library/Preferences/.GlobalPreferences com.apple.mouse.tapBehavior -int 1


It would enable tap to click for built-in MacBook Trackpads for the root user, which would also affect the login screen. There are similar commands to enable it for Bluetooth-based Magic Trackpads as well.

Unfortunately it doesn’t seem to work in OS X 10.8 anymore. Is there some other way of doing this in Mountain Lion?
Turns out you can add this as a function in the Terminal:

sudo defaults write com.apple.driver.AppleBluetoothMultitouch.trackpad Clicking -int 1

That worked for me, thanks to these guys - http://forums.macrumors.com/showthread.php?t=1218257
