Why is my Mac not showing up on screen mirroring?

I recently tried to connect my Mac to my TV using screen mirroring, but it just isn’t showing up. I’ve checked all the connections and settings multiple times, but my Mac still doesn’t appear on the list of available devices for screen mirroring. It’s really frustrating because I was able to do this without any issues before. Everything seems to be up-to-date, and both my Mac and TV are on the same network. I just can’t figure out what’s changed or why this problem is happening now. It’s crucial for me to understand what might be causing this, as I rely on screen mirroring for work presentations and watching content on a bigger screen at home. Has anyone else experienced this issue? What could be causing my Mac not to show up on screen mirroring?

Sometimes the issue can be related to security settings. Here are a few things you should check:

  1. Check AirPlay settings on your Mac: Open ‘System Preferences’ > ‘Displays’ and make sure AirPlay Display is set to ‘Mirror Built-In Display’.
  2. Adjust Security Settings: Go to ‘System Preferences’ > ‘Security & Privacy’ > ‘Firewall’ and make sure ‘Block all incoming connections’ is not selected.
  3. Verify sharing settings: In ‘System Preferences’, go to ‘Sharing’ and make sure all necessary sharing options are enabled, particularly ‘Screen Sharing’ and ‘AirPlay Receiver’.

I’ve faced this issue as well, and what worked for me was resetting the network settings. Here are the steps I took:

  1. Ensure both devices are on the same Wi-Fi network: Check if both your Mac and TV are connected to the same network. Sometimes, even if it seems like they are, they might not be.
  2. Restart your router: Unplug your router for about 30 seconds, then plug it back in and wait for it to reboot fully. This can help reset any connectivity issues.
  3. Forget and reconnect Wi-Fi on both devices: On both your Mac and TV, forget the Wi-Fi network and then reconnect to it. This can often solve any hidden connectivity issues.

When my Mac didn’t show up on the screen mirroring list, I had to check and adjust some software settings. This is what you can try:

  1. Update macOS: Go to System Preferences > Software Update and make sure your Mac is running the latest version of macOS. Sometimes updates include fixes for screen mirroring issues.
  2. Check Firewall settings: Navigate to System Preferences > Security & Privacy > Firewall and ensure that mirroring is allowed. You might need to click the lock to make changes.
  3. Enable Bluetooth: While not always necessary, having Bluetooth enabled can sometimes help your Mac and TV find each other more reliably. Just go to System Preferences > Bluetooth and switch it on.

I had a similar issue and found that the problem was with my TV’s settings. Here’s how I fixed it:

  1. Update your TV’s software: Check if there are any firmware updates available for your TV. The process varies by brand but usually involves going into the settings menu and looking for a software update option.
  2. Enable screen mirroring or AirPlay on your TV: On your TV, go to ‘Settings’ > ‘General’ > ‘AirPlay Settings’ and make sure that AirPlay or screen mirroring is turned on.
  3. Restart both devices: Turn off your Mac and TV completely. Wait a few seconds, then turn them back on. This reboot can sometimes refresh the connection and make your Mac visible for screen mirroring.

I recently dealt with this issue and here’s what helped me:

  1. Check the hardware connections: Ensure there are no loose connections that might be disrupting the signal.
  2. Verify network stability: Run a speed test to make sure your Wi-Fi network is stable and not experiencing any interruptions.
  3. Use a direct connection: Temporarily use an HDMI cable to connect your Mac to your TV. This helped me verify that my Mac was working fine and the issue was with the wireless connection.
  4. Reboot everything: A full reboot of your Mac, TV, and router can sometimes solve the problem. Ensure all devices are powered down completely before restarting them.
