macOS is not permitting me to change the file permissions of any file! whenever I try to add the admin which is me, finder gives me this error:
you don't have necessary permission - operation not permitted
In spite of the fact that I am the sole user
I have tried chmod, again same error - operation not permitted
The permissions are as follows!
Screenshot of the operation not permitted error I getting


Terminal.app.Terminal.appis stored in/Applications/Utilities, there is no relation to the home directory as such. Changing the permissions of applications which are part of macOS is not possible as all of them are protected by SIP. – nohillside Nov 28 '17 at 12:32
