Sorry, real amateur here. I read about this thing and how dangerous it is to have it open. https://support.apple.com/et-ee/HT204012 I haven't opened enabled it deliberately and the instructions look pretty big to do it by accident. At the login window, log in with the user name ”root” Does it mean I would notice immediately if Root is enabled? I only have one account since I got this mac, Administrator one. It would be impossible to accidentally enable root account? And how to make sure it is NOT enabled? Can I check somewhere?
