Hi @wendycollins4 ,

Welcome to Trend Micro Home Users Community!

There could be several reasons why screen mirroring isn't working between your iPhone 12 Pro Max and Apple Box. Here are some common issues and troubleshooting steps you can try:

  1. Ensure Both Devices Are Connected to the Same Wi-Fi Network: Screen mirroring requires that both your iPhone and Apple TV are connected to the same Wi-Fi network.

  2. Restart Your iPhone and Apple TV: Sometimes, simply restarting for few seconds both devices can resolve temporary glitches.

  3. Update Software: Make sure that your iPhone and Apple TV have the latest software updates installed. Updates can often include bug fixes that address issues like screen mirroring problems.

  4. Check AirPlay Settings on Apple TV: On your Apple TV, go to Settings > AirPlay and make sure AirPlay is turned on. Also, check if "Require Code" is turned off unless you specifically want to enter a code each time you connect.

  5. Check AirPlay Settings on iPhone: On your iPhone, swipe down from the upper-right corner to open Control Center. Tap and hold the Screen Mirroring button (rectangle with a triangle inside). This should show your Apple TV as an option. Tap on it to start screen mirroring.

  6. Disable/Enable Airplane Mode on iPhone: Sometimes toggling Airplane Mode on and off can refresh the network connection on your iPhone, which might help with AirPlay connectivity.

  7. Reset Network Settings on iPhone: If other methods don’t work, try resetting your iPhone's network settings. Go to Settings > General > Reset > Reset Network Settings. This will reset Wi-Fi networks and passwords, cellular settings, and VPN settings.

  8. Check for Interference and Range: Ensure that there are no physical obstructions or interference (such as large metal objects) between your iPhone and Apple TV that could weaken the signal.

  9. Try a Different Device: If possible, try using a different iPhone or iPad to see if the issue persists. This can help determine if the problem is with your specific iPhone or a broader issue.

Hope this helps!
