iPhone Mirroring not working on Mac

Update to my previous post. I was finally able to get it working. What I did wrong initially was that my Macbook was connected to wired Ethernet through a usb-c adapter. Even though it was on the same subnet as the WiFi, that was not enough. Both the Macbook and the iPhone have to be on WiFi. Ethernet will not work. I hope this is something that is changed later because I prefer Ethernet when docked with my external usb-c monitor.

This leads me to my second issue. Since I am docked to said monitor, I also use the built in external monitor speakers. MacOS cannot natively adjust volume of external speakers so that means the iPhone mirror app is playing audio at full blast, at least in games. So the iPhone mirror app needs a volume adjuster.

Last issue, the app window size. My usb-c monitor is a 43" 4K so I use the More space option in display settings which is 1:1 scaling. This means the iPhone Mirror app is way too small to see, even on the larger size setting. The window is fixed and the larger setting only increases it very little. I was hoping to be able to increase the window size much more than that.

So as it is now, the iPhone mirror app is not acceptable to me. I still stand by my previous comment of waiting a year or so before trying again.

Hallelujah - Success!!

After two months of hand-holding by a couple of senior apple support folks, we finally got mirroring restored. This session, we logged out both devices from iCloud, *waited for log out to complete*, restarted and logged back in. We then waited until contacts and calendars began repopulating before we tried to mirror iPhone.

This time, it worked perfectly, like it did during the public beta 2 months ago. I was able to change security settings, revoke access and reapprove it. It worked as it should and we’re not sure why.

I fixed it by turning off VPN on both devices even though they were both connected to same VPN host. So of no use to me if I can't use with a VPN running.

Problem solved by sheer luck. Settings > General > Airplay and Continuity > Set Automatically Airplay to "Ask". It won't connect on Automatic.

Same experience. Turned off VPN (Nord) connection to laptop, and mirroring worked fine (no phone VPN in use).

I found that if I have ExpressVPN enabled, Mirroring does not work.

1000 bonus points for you, thank you! This fixed it for me as well with the 'Can't revoke, try again later' variety of the bug. If you're worried about not having any devices to authenticate the 2FA through, in my case it also worked to go one at a time - I signed out on my Mac first, restarted and reauthenticated via the phone, then did the same for the phone and iPhone Mirroring just decided to treat it like a new device setup and worked. I checked after just resetting the computer and it did need this done on both devices.

On your Mac go to iPhone Mirroring app > Settings > Revoke Access. Then re-pair your iPhone.

This might not be new to you, but have there is a support document about iPhone mirroring here - iPhone Mirroring: Use your iPhone from your Mac - Apple Support - includes settings you need on both devices.

Good luck.

I can also confirm that as of macOS 15.1 and iOS 18.1, it still does not work. This is with iPhone 13 Pro and Macbook Air M3. I am also in the US and meet all the requirements, and I completed all troubleshooting steps on the support document including rebooting.

When I launch the iPhone Mirroring app, for a split second it will say Unlock iPhone and then promptly display unable to connect. The app gives the impression that it is not even trying.

I will just file this under broken/buggy new feature that will probably be fixed in the next year or so.

I had the same issue once I updated the IOS on my macbook and then I restarted the iphone and then it worked.

This instruction shows up in lots of help docs. For me there's nothing to revoke because my phone has never been listed.

In MacOS settings, iPhone Mirroring supposedly requires the following to be activated: System Settings > Desktop & Dock > Widgets > use iPhone widgets.

It doesn't seem to do anything whether on or off.

If you're using an outdated device it probably won't work, try updating iOS or macOS or resetting settings/network settings

I'm using M3 Macbook Pro / OS 15.1 and iPhone 13 Pro / iOS 18.1 and cannot get a connection.

I live in the U.S. and I've followed all troubleshooters on the official iPhone Mirroring help doc without success.
