For an unknown reason all the system features of my mac (macOs High Sierra, Mbp late 2012) are inaccessible and it is impossible to launch the applications. An error message shows that the application is incomplete or damaged. All documents are intact. It seems to be a problem in the root of my administrator user account. I managed to create a second admin user account from which I can use my applications. But, since the file sharing of my first admin user account has not been enabled, I cannot access my documents from the new admin user account.
Is there a Terminal command addressed from the new admin user account, which allows to enable file sharing from my second user admin account?
This will allow me to overwrite the first corrupted admin account and use my 32bit!!!!!!! applications with my files without having to completely reinstall the system at this point in my backup.
