What does the option "Allow AirPlay for: Current user" do?

The option "Allow AirPlay for: Current user" specifically enables AirPlay access exclusively for the user currently logged into the device. This means that only this individual can stream audio and video to compatible AirPlay devices, ensuring that personal content remains private and secure. By restricting access in this way, it prevents other users of the same device from unintentionally accessing or controlling AirPlay features, which is particularly useful in shared environments or when multiple user accounts are present on the same system.

The other choices do not reflect this targeted approach to user access. Limiting access to guest users or disabling AirPlay entirely would not allow the current user to make use of AirPlay, while allowing any user on the network would disregard the security and privacy intended by this particular setting.
