Tap to click on OS X login screen?

This Mac OS X Hints article explains how to do this.

Quote:

After some digging, I found it in a hidden preferences file called .GlobalPreferences.plist in my user's Library/Preferences folder. I found the same file in the top-level /Library/Preferences folder, and then added the com.apple.mouse.tapBehavior setting as a class of Number with a value of 1 and saved the file.

EDIT: Or, a user suggestion:

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

EDIT2: Since I don't have a Mac with a trackpad and OS 10.5 or later (The only Mac with a trackpad I have access to is a Powerbook running 10.4), please let me know what the output of

ls ~/Library/Preferences/com.apple.driver*

is. Hopefully you'll have a file like /Users/jnet/Library/Preferences/com.apple.driver.AppleHIDMouse.plist which you can copy to /Library/Preferences to make this behavior work.

EDIT3: I'm playing with a MacBook Pro at an apple store right now. I think the file is ~/Library/Preferences/com.apple.systempreferences.plist -- Try copying that file to /Library/Preferences/...

yes, Open - settings, - trackpad - there should be an option listed that allows taps for clicks.
