How can I make the OS X privilege escalation popup less annoying?
Solution 1:
Mac OS X's authorization rights and behaviours can be adjusted through the /etc/authorization file.
You must take care when altering this file; mistakes can lock you out of your Mac. There are instructions at the top of the file to get you started.
To extend the period of time authorization is granted, look for the appropriate timeout field and increase the value as needed.
