Make Airport not accessible
I have an Airport Express in my LAN, which is connected to my HiFi System and my Printer. The other MacBooks in this room are in the same LAN, but i want them to have NO access to the Airport, especially AirPlay. If i try to set an AirPlay password via the AirPlay Speaker password others can just open the AirPortUtility and delete the password.
Anyone got an idea how to make the AirPlay only accessible for me?
Thanks in advance.
