Question about performing actions with privileges

[spieglt]

A comment here (https://github.com/potionfactory/LetsMove/blob/master/PFMoveApplication.m#L481-L485) says "AuthorizationExecuteWithPrivileges is deprecated. We want to still use it since there's no good alternative (without requiring code signing)." Does anyone know if there is any alternative?

In my application, I need to add a wireless network to the top of the preferred networks list and later remove it. For this I can use this function: https://developer.apple.com/documentation/securityfoundation/sfauthorization/1417652-obtainwithright. But then the password is still in the user's Keychain, and I'd like to clean that up as well. There is another function, CWKeychainDeleteWiFiPassword, but it does not have a parameter to pass in an authorization, and so unless you're running it as root, you can't delete from the system Keychain. I don't want to use SMJobBless as I don't want to install privileged helpers (this is a standalone utility that should not require installation), and I don't want to pay Apple $99/year just to allow a user to delete a password. Thanks for any help you can provide.
