User profiles

[jamesg1985]

Is there a way of making it impossible to create a new user, even if you're the administrator?

No, sorry. That's part of the administrator rights.

It's not possible, as vmachiel offers.

My workaround, used in the small company I own is to create a Standard (or Managed) user account from a single Admin user account, then make the Admin account hidden using Terminal. I have a couple of Macs for my clients' use that just have the Guest user account enabled, with the Admin user account hidden - the KISS principle for their usage needs.

https://support.apple.com/en-us/HT203998 offers a pretty good description of the process IMHO. Unhiding an account is also pretty simple.

I guess doing this is like corrupting the iOS. Nope not possible.
