It seems that Mac OS X Software Update does not automatically check for updates if the current user is not privileged to install them. For security reasons I am using a standard account and I have set Software Update to check for updates on a daily basis, but it does not bother to check because I'm not running as admin. I have to manually do the check. I can do that in my standard account, it just asks me for an admin password. Is there a way to force Software Update to do the automatic check even if I'm using a standard account?
