Parental Controls Always Allow does not work
This gave me enough info to fix the Minecraft launcher.  The prior answer works, but has an ugly menu name, which my son would pester me about.  So instead, I fixed the Minecraft.app setup.

In a nutshell, in terminal:

cd /Applications/Minecraft/Contents/MacOS
mv JavaApplicationStub Minecraft
cat &gt; JavaApplicationStub &lt;&lt; EOF
#!/bin/sh

exec `dirname $0`/Minecraft "$@"
EOF
chmod +x ./JavaApplicationStub


Basically, it would appear that ParentalControls expects the application being run to match the name of the executable (which is not the case with the distributed app: It's Minecraft.app, and JavaApplicationStub), so by moving the executable to match the app name, it works.  I had to create a shell script to actually exec the executable because I got "Path not found" otherwise.

This seemed to work.

I only put this here because it worked for me.  If you do not understand the code block again, please keep in mind you might have to re-download the app (or make a copy first).
