AppleSetupDone not working on Catalina

I have been trying to log on to my MacBook Pro but the computer doesn't seem to recognize my admin account. The issue happened before I updated to Mac OS Catalina and now I can’t use AppleSetupDone in terminal to recover the admin account. When I try to mount in terminal the computer displays a message saying read/write mode. How can I use the terminal without being in read/write mode and use the command AppleSetupDone?

What happens when you boot up under an external drive? Are you able to gain access to the internal drive or are you still blocked?

When I start up the Mac I get to the login screen, but I can only access one account. As if the Mac does not find the other admin.

I could fix the problem before I updated to Mac OS Catalina, but now the commands that I used in Terminal don’t work anymore.

Here are the commands that i used before.

mount -uw /

rm /var/db/.AppleSetupDone

I fully understand... Can you please give the external drive a try.

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

Can you give me a detailed step by step guide on how to do that?

Look for the Catalina OS Installer app using your systems File Search to see if you have it already, if not go to the App store and download it again. Once its downloaded, it will automatically run. Exit out of the app and locate it again with File Search as you want to make a copy as the original will often be erased after its run.

Get a fresh USB-C drive or one you don't care to wipe out. Run Disk Utility app to format the drive to GUID/APFS, then run the OS installer again this time making sure you are pointing to the external drive. Let it run at the end exit out and now when you restart with the drive connected press the Option (⌥) key to get to the Startup Manager now using the arrow keys select your external drive.

Reference: Mac startup key combinations
