User status changed from Admin to Standard after macOS reinstallation on my iMac.
During an update to the above recent MacOS we had a power blackout. When power returned my Mac would not complete the restart. I rebooted into Recovery Mode and did Reinstall OS From Internet. All good after that except I am now a "Standard User" and NOT an "Admin User" as I was before. There is NO listing for an Admin User, only me. As a result I cannot change my User Details to Admin or Add Another User as Admin as there appears to be no Admin User Name nor Password to enter at the prompt. Any help or advice would be gratefully appreciated. Thanks and cheers! Sam
