macOS Catalina - change account name?

Thanks, but I already saw this - the problem is that I don't get the "Advanced Options" menu when logged onto the new/alternative admin user I created.

The "Advanced Options" menu is only accessible from my original admin user - and that obviously doesn't help, when the change has to be made from another admin user :(

Hi, thanks for your reply!

Yes, I checked the box to make the new user an admin.

When logged onto my orignal admin user, and in the "Advanced Options" menu, my full name is spelled correctly with uppercase initial letters. It is only the account name which has the lowercase initial letter (the account name being "janne" with a lower case j.

From my original admin user I can change the account name of my new/alternative admin user, and there I can use an uppercase initial letter.

But, if you mean that this account name is by default supposed to have a lower case initial, I guess I'll just have to leave it.. However, is seems strange to me - as I am able to change it for the alternative admin account.

Sorry if I was being unclear; when I am logged onto the alternative admin user that I created solely to fix this issue, it doesn't give me the "Advanced Options" at all when I right click.

I only get the "Advanced Options" when I am logged onto my original admin user, that was created when I set up this new Mac.
