I don't have a server or anything, but I have 1 iMac running Snow Leopard in my office that a nontechie uses. I would like for it to automatically install any new updates when the computer is told to shut down every day. I know I can set Software Update to check for updates daily, and download them if they exist. But what about actually installing them without confirming each time. I don't want to do a cron job, because if that person is working late it wouldn't be good if it tries to shut down on them. Also that person is running with a std user account, so to install updates I have to enter my admin level account's credentials. Is there any way to do this?
