Macbook Pro admin permission

First of all, you cannot grant admin permissions to yourself.

Only an admin account can grant admin permissions to others (obviously).

Second of all, you need to logged out from the account to which you want to grant these permissions.

So, to summarize:

If account A is an admin and you want to make account B an admin as well:

1) Log out from account B if you are logged in (do not just use Fast User Switching)

2) Log in to account A, select account B is System Preferences->Users & Groups, and check "allow user to administer this computer"

you press "Click the lock to make changes." then enter an administrator name and password, and click the user you want to allow to admin. the "Allow user to administer this computer" buuton shouldn't be grayed out then.

Use the Terminal command below to verify if your account is an Administrator

id -Gn username | grep -q -w admin && echo True || echo False

If the $USER  is admin, then True will result.
