Cannot delete account in Mojave Mac os
I have the same situation - I set up another account to work on issues. Now, I no longer need it but cannot delete the account. I've tried all steps - nothing. Please, can you help?
If you've tired all the steps then there's nothing left! But I'll give it a shot anyway.
To start with have you tried all the steps here and what happens when you try?
