I need to change a sharing-only account to a standard one.
From the Advanced options in System Preferences's Users and Groups I can choose the login shell and select a home directory, however there is no option to build the latter.
How do I build a home directory for a existing user account?
I'm on macOS 12.5 Monterey.
Please note: this question is different from OS X: Change sharing-only account to 'normal' account because in that case the user's home folder is present.
