Notification Center keyboard shortcut broken

http://support.apple.com/kb/PH11243

I tried resetting pram, too, but it did not work. Other keyboard shorcuts work, but not notification center. I have tried many different key combinations and they are all accepted in System Settings -> keyboard, but the notification center just doesn't open when I press them.

Resetting PRAM did not fix the problem for me, either.

I worked around it locally by using the MacOS Automator to create a new Workflow. The workflow had a single "Run Applescript" action in it where the applescript is as follows:

on run {input, parameters}

tell application "System Events"

tell process "Notification Center"

click menu bar item 1 of menu bar 1

end tell

end tell

end run

Then I saved the workflow and used BetterTouchTool (http://www.boastr.de/) to bind a "Start Automator Workflow" trigger to a a keyboard shortcut.

Resetting PRAM didn't work for me. This solution is great, but I don't think the AppleScript is compatible with Mavericks or Yosemite.

This AppleScript works in Yosemite:

tell application "System Events" click menu bar item 1 of menu bar 2 of application process "SystemUIServer" end tell

BetterTouchTool, as mentioned, or Alfred (http://www.alfredapp.com/) can be used to assign a hotkey to the script.

Resetting PRAM worked for me.
