It’s one of those moments that can really throw a wrench in your workflow. You’re trying to show something on your iPhone to a colleague or perhaps just want to use your Mac’s bigger screen for a presentation, and suddenly, that familiar "Connection Interrupted" message pops up. It’s frustrating, especially when it happens right after you’ve managed to get the mirroring started, only for it to drop after a couple of seconds.
This isn't a rare glitch, and it seems to be cropping up for users with various iPhone and Mac models, often after recent software updates. One user, for instance, found their iPhone 16 Pro mirroring to a MacBook Air (M1) worked flawlessly on standard Wi-Fi but faltered when relying on Starlink in a remote area. The connection would establish, show the iPhone screen for a brief moment, and then disconnect.
Another user experienced a similar issue after updating their M2 MacBook Air to macOS 15 and their iPhone to iOS 18. The mirroring would connect, allow interaction for a second or two, and then display the dreaded "Connection Interrupted" error, despite all devices being near, powered on, and with Wi-Fi and Bluetooth enabled.
What’s interesting is that the troubleshooting steps often tried – restarting devices, changing private Wi-Fi addresses, even logging out of iCloud – don't always hit the mark. This suggests the problem might be a bit more nuanced than a simple connectivity blip.
Digging a little deeper, some users have found that the culprit can lie within the network settings themselves. One significant clue came from comparing Wi-Fi modem settings. It turns out that not all Wi-Fi channels are created equal when it comes to iPhone mirroring. For one user, only specific channels on both the 2.4GHz and 5GHz bands worked reliably. Adjusting the IEEE802.11 Mode to 802.11n on the 5GHz band, along with selecting a particular Wi-Fi channel (W52), resolved the issue.
Another common thread points towards network congestion or interference, particularly with newer Wi-Fi standards. A user with a Wi-Fi 6 capable modem found that mirroring would interrupt every few seconds when both their iPhone and Mac were connected to the 6GHz band. Switching both devices to the 5GHz band completely eliminated the interruption, leading to smooth mirroring and even improved Continuity Camera performance.
Firewall settings can also play a role. In one case, after updating to newer OS versions and enabling a firewall, mirroring started failing. Disabling the software firewall on the Mac, followed by a reboot of both devices, surprisingly fixed the connection interruptions. It seems that sometimes, the firewall, even when seemingly disabled, might require a restart to properly reset its trust settings for new connections.
So, if you're finding your iPhone mirroring is cutting out, don't despair. While the exact cause can vary, it's worth looking beyond the obvious device restarts. Checking your Wi-Fi channel settings, experimenting with different Wi-Fi bands (especially if you have Wi-Fi 6), and reviewing your firewall configurations might just be the key to getting that seamless connection back.
