How to check a Mac
If we emailed you that someone tried to turn off SentryScreen on a Mac, or that a Mac has not checked in, these steps take a few minutes.
-
Open SentryScreen on that Mac
Click the SentryScreen icon in the menu bar. It should say Protected. If it says anything else, or the icon is missing, sign in to an administrator account, open SentryScreen from the Applications folder and follow what it says.
-
Make sure your child's account is Standard
Open System Settings, then Users & Groups. Your child's account should say Standard, not Admin. Anyone with an administrator account can stop or remove any app, SentryScreen included.
-
Change the parent PIN if you are unsure
If your child might know it, choose a new one: click the SentryScreen icon, then Settings…, then Change PIN.
