I have iTunes on set up of my iMac to share an iTunes library between two different users. This means that if one person forgets to quit iTunes, the other user has to log in to the other account and quit itunes before they can use it on their own account.
So is there a way to use applescript to quit an application for all users? I know it's easy to tell it to quit an application for the current user, but haven't been able to figure out if it is possible to have it quit another user's instance of that application.
You can simply use an shell (terminal) command.
You can either enter killall iTunes in the terminal, or do shell command "killall iTunes" in Applescript.
It doesn't sound very healthy, but it's actually just a 'Forced Quit'.
