how do I remove my own master login?
New to Apple products. Just Bought MacBook Air and somehow while creating users I have created a master login to turn on the Macbook Air. After entering the password for that, then a login for my account and other users to access shows up. How do I remove this so that only one login password is required by whichever user to access and use?
I have tried to access and change through user preferences / users / apple ID or iTunes. No luck
MacBook Air (13-inch, Early 2015), OS X El Capitan (10.11.3)
