How do I fix connection drop when Mirroring iPhone to MacBook Air?

I was having this exact same issue and couldn’t find a single solution. Every fix I came across was for iPhones that wouldn’t connect at all, but like you, mine was connecting for 1-2 seconds before disconnecting with the “Connection Interrupted” message.

After weeks of troubleshooting — restarting all my devices, force restarting, disconnecting and reconnecting, forgetting iPhone on Mac iPhone Mirroring app (and vice versa), tweaking every single network and Wi-Fi setting imaginable, contacting IT about router settings (I’m on campus Wi-Fi), reaching out to Apple Support on three separate occassions, logging in and out of iCloud on both devices, manually changing DNS settings (even though I had no idea what I was doing), deleting VPNs and proxies, and even spending 5+ hours reinstalling macOS Sequoia in recovery mode which an AppleCare advisor suggested — I was completely stuck.

Finally, a senior AppleCare advisor (shoutout Tim!) helped me realize the solution was so much simpler than expected:

Change the Private Wi-Fi Address setting from “Fixed” to “Rotating” on both your Mac and iPhone.

Apparently, on some public networks, the default setting is “Fixed” for security reasons, but iPhone mirroring requires it to be “Rotating” to work properly. Here’s how to change it:

1. Open Settings on both your iPhone and Mac.

2. Go to Wi-Fi.

3. Tap the (i) icon next to your Wi-Fi network on iPhone / click Details next to your Wi-Fi network on Mac.

4. Find Private Wi-Fi Address with a dropdown menu next to it.

5. If it says Fixed, change it to Rotating. (If it’s already set to Rotating, unfortunately, this might not be your fix.)

6. Restart both your iPhone and Mac.

7. Enjoy seamless iPhone mirroring!

I totally understand how frustrating this issue is, so I really hope this helps someone who’s been struggling as much as I was! Let me know if this works for you!
