My kids (somehow) talked me into installing Minecraft on my iMac. I have separate accounts for them with the Parental Controls feature enabled for each account. When they start up Minecraft on their account it prompts for admin access as expected. If I enter my username/password and click 'Allow Always' the dialog goes away for a couple of seconds then pops back up. If I click 'Allow Once' the games starts up and they can play.
How can I allow them to always play without requiring me to come over and enter my info?
