Since postflight/upgrade/install scripts run with privileges (assuming the package requires RootAuthorization), couldn't you just have your plugin write the data some place world-writable (like /tmp) and then have the postflight script read that and write to the system-wide prefs file? I'm writing an Installer plugin which needs to perform a privileged operation (writing to a system-wide preference file), and I'm wondering how I can reuse the authorization already made when installing the files. I have witnessed many installer plugins that execute after the file copy stage that make changes to otherwise protected files without requiring the user to re-authenticate, but I cannot understand how they do it. Currently, I create a new Authorization reference and have the user authenticate, which means the user will have to type its password in a new authentication dialog, before calling a helper tool with AuthorizationExecuteWithPrivileges to carry out the actual operation. I would really like to avoid having the user type its credentials in two dialogs in a row (first for copying files, second for writing to the preference file). P.S. I sent the previous email from the wrong address. Blame Thunderbird. This email sent to greg.neagle@disneyanimation.com This email sent to site_archiver@lists.apple.com
