Manage parental controls from another Mac
After you set restrictions for a child on a Mac, you can manage parental controls from a different Mac. Both computers must be on the same network.
On the Mac the child uses, choose Apple menu > System Preferences, then click Parental Controls.
Note: When you open Parental Controls preferences, if you see the message “There are no user accounts to manage” you need to add a new user account and turn on parental controls for it.
Don’t select the child’s account at this time.
Select “Manage parental controls from another computer”.
If you don’t see this option, there may be a user selected on the left side of Parental Controls preferences. Command-click the selected user so that no user is selected.
On the Mac you want to use to manage the child’s parental controls settings, choose Apple menu > System Preferences, then click Parental Controls.
Click the lock icon to unlock it, then enter an administrator name and password (or if your Mac has Touch ID, use Touch ID).
Select the Mac the child uses.
Enter the administrator name and password for the Mac the child uses.
Select the user to be managed.
You can now change the child’s parental controls settings and monitor the activity logs.
