Make my MacBook Air user account admin again

I tried to change the admin username on my Mac, but it accidentally changed the account to Standard, how can I get the admin account back? It’s refusing to take the old and the new user name

Here is an article written by a respected forum contributor which should allow you to do what @PeterChrisM was suggesting:

Restarting Setup Assistant to create Admin user account - Apple Community


If these instructions don't help to create a new admin user account, then you will need to perform a clean install of macOS as mentioned by @PeterChrisM.


FYI, after creating a new macOS user account, you will then need to fix what you broke on the old admin user account by using the instructions in this Apple article as a guide:

Change the name of your macOS user account and home folder - Apple Support


Keep in mind a clean install of macOS will destroy all data on the drive, so make sure you have a backup of your data. If you don't have a current backup, then you will have to do a lot more work to be able to access the data to back it up now that you don't have a valid admin user anymore. How this can be done may depend on the exact model of Mac involved since it may be impossible to access that data on a 2018+ Mac if you are unable to authenticate when accessing Recovery Mode.

You need to create a new admin user, 


reboot into Single User mode:


Boot to single user mode while powering up  hold down (⌘-S)


Launch Terminal and type exactly


sbin/fsck -fy  and press run or return


/sbin/mount -uw / and press or return


m /var/db/.AppleSetupDone


Restart




Setup Assistant should display and prompt you to create a new user. New user will automatically have admin rights. Should work for you.
