Cannot disable parental controls for Admin user
I found a solution thanks to @nohillside,
I created a new admin user, loged out of the old one and loged into the new one but I was not able to downgrade the old admin account to standard, so I did this :

dscl . read /groups/admin GroupMembership


then

sudo dscl . delete /groups/admin GroupMembership Anakojm


Then I restarted my mac and created a stantard user with the same name (Anakojm) and I get this message :


  A home folder named Anakojm already exist use it ?


Then I clicked yes and disabled parental control, and upgraded it again.
