use a user name instead of your name?

[StarJump]

So if any furry who has a apple account have you used your furry name ? im making a secondary account for the imac just so i can update it and for how old it is i dont want to risk signing in my main one to a old version of mac os becouse of well security flaws but i have to sign in just to download the update XD

so i was wondering if anyone had any problems making a apple account using their furry name or any username instead of your real name ?
