How to Access Administrator in a Macbook

Click the 'Apple' icon in the upper-left corner of the screen and select 'System Preferences.' Click the 'Accounts' icon.
Look at the list of accounts on the left side of the window. Under the name of an account is the privilege level of the account. These can be 'Admin,' 'Standard' or 'Sharing Only.' If 'My Account' is listed as an 'Admin' account, you are currently logged in as an administrator. If it is not, proceed to the next step.
Click the 'Apple' icon and select 'Log Out.' Confirm that you want to quit all applications and log out in the pop-up window. Once logout is complete, the login window displays on the screen.
Click on a user account with administrator privileges and enter the password. Press return to access the administrator account.

How to Use an iPhone as an Apple TV Remote

Turn on your iPhone and launch the App Store via the 'App Store' icon. This is the blue icon that is located by default on the bottom row of icons on the home screen of your iPhone. It will be listed literally as 'App Store.'
Search for the Remote app by typing 'Remote' into the App Store's search bar. Choose to install this app on your iPhone. You will have to input your iTunes username and password to confirm the installation procedure.
Turn on Home Sharing within iTunes. Click on the 'Home Sharing' listing on the left navigation screen within iTunes once you have launched the iTunes program.
Enter your Apple ID and password when prompted.
Connect your iPhone to your home Wi-Fi network. If you do not already have this connection established, click on the 'Settings' icon of your iPhone.
Click on the second listing within 'Settings' that reads 'Wi-Fi - Not Connected.' Ensure that the 'Wi-Fi' setting within this listing is switched to 'On.'
Select a network in the 'Choose a Network...' field. There will likely be more than one listing here. Be sure to select your home Wi-Fi network. This will connect you to Wi-Fi. If your Wi-Fi network is password protected, when selecting it for use, you will need to input this password into your iPhone.
Launch the Remote app and sign into Home Sharing when prompted using your iTunes ID and password.
Control your Apple TV by using your iPhone as the remote with the Remote app now launched and Home Sharing and Wi-Fi enabled. The Remote app uses an interface that is identical to how you navigate and browse videos on your iPhone, iPad and iPod Touch, so finding and purchasing movies and controlling them on your Apple TV will be immediately intuitive. You can back out of the Remote app and resume normal use of your phone whenever you like. The physical remote that ships with the Apple TV can still also be used.
