Ensure both devices are on the same Wi-Fi network and verify that mDNS is enabled on your router.

Step-by-Step Instructions:

1. Verify Network: Ensure the MacBook and ViewBoard are connected to the exact same SSID.

2. Enable AirPlay Receiver:

• Open the vCastReceiver app on your ViewBoard.

• Go to [Settings] and ensure the AirPlay toggle is "On."

3. Refresh Connection: Turn the Wi-Fi off and on again on your MacBook, then check [Control Center] > [Screen Mirroring].

4. Network Configuration (For Admins):

• Ensure AP Isolation is disabled on the router.

• Verify that mDNS (Multicast) is allowed on the network, as AirPlay relies on it for device discovery.
