Re-running OS X Setup Assistant in Catalina

Apparently I should’ve not copied and pasted things I read on the Internet into Terminal. Managed to demote my user account to a Standard one.

My machine had no other Admin account #FML

This old single-user mode & .AppleSetupDone removal workaround didn’t work in Catalina. How to re-run the OS X Setup Assistant

What finally fixed the issue for me:

1. Cmd+R to enter Recovery mode
2. Enter my account password
3. Use Disk Utilities to mount the FileVault disk (Macintosh HD)
4. rm /Volumes/Macintosh\ HD\ -\ Data/private/var/db/.AppleSetupDone
5. reboot

6. Create a new temp account with admin privilege
7. Log in to that account & promote my existing one to Admin
8. Reboot
9. Log back in to that account & remove the temp one
10. Let out a big sigh #NoteToSelf

This might also work: Enable the root account and use it to promote my standard one. Enable root in Catalina
