New iPhone 18 pro max not mirroring on Macs

Hi there

Please try this

• Toggle Wireless: Turn Wi-Fi and Bluetooth off and back on on both your iPhone and your Mac. 
• Verify Apple Account: Ensure both devices are signed in with the same Apple Account (Apple ID) and two-factor authentication is active. 
• Proximity & Lock: Keep your iPhone unlocked or nearby, and make sure it is not actively using a Personal Hotspot or sharing an internet connection. 

Advanced Troubleshooting Steps

1. Wired Jumpstart: Plug your iPhone directly into your Mac using a USB cable, force quit the iPhone Mirroring app (via Activity Monitor if necessary), and attempt to launch the app again. 
2. Revoke Access: Open the iPhone mirroring  app on your Mac, go to Settings in the menu bar, and select Revoke iPhone Access (or reset the iPhone Mirroring setup). 
3. Restart Both Devices: Perform a complete restart on both your Mac and your iPhone after clearing the access configuration, then re-pair them following the on-screen prompts. 
4. Sign Out of iCloud: If the connection continues to drop or fails to authenticate, sign out of your Apple Account on both devices, restart them, and sign back in. 

Thanks for getting back to me. I had already tried the top 3 bulleted points. No luck. So, I then connected my iPhone via a USB-C cable to my Mac and rather than force quit the app, I checked to see if it would recognize my phone. It did, and it mirrored correctly. I then closed out the app, disconnected from my Mac, and relaunched the mirroring app, and voilà, it works again. I'm now moving on to my laptop. 

Very much appreciate your advice!

Best,

Howard

Thank you. Connecting temporarily with a cable fixed the issue. After spending hours with ChatGPT and Gemini this was the fix!!

I already try usb connected and all steps, but nothing works,it use to work with my iPhone 15, but not with my new iPhone 18 pro max
