Q: appleidauthagent on startup.

So I did reinstall my Mac through system recovery a long time ago. When it was finished I had to set it up as a new Mac (including adding a root user)

After I logged in on my own account I deleted that extra user. But since then a screen randomly pops up on startup asking me for that users password. (My main account password doesn't work on it, only the one I used for that extra account)

It is really annoying, but the worst part is that when it happens after login. When my Mac goes to standby/sleep/screen off and I wake it up again, it forgets my Wifi password and won't auto connect. So I have to click on my network and enter my password. After that it connects but it gives me an error saying I have to reset keychain to default. When I click on the reset button on the popup I have to enter a password again but I can't enter anything to the field. When I click on OK even when the password is wrong or the field is empty, the popup disappears.

This only happen when he asked for the Appleidauthagent paswword on login.

O and he randomly asks to enter my iCloud password after login.

I don't know the name of the removed root account btw.

Thanks,
