iPhone Mirroring & Continuity not working on MacBook Pro M1 (Continuityd missing)

Hi everyone,

I’ve been trying for days to get iPhone Mirroring and other Continuity features (copy-paste, Continuity Camera, Handoff, etc.) working between my iPhone and MacBook Pro M1 (2020), but nothing works — the devices simply don’t connect.

Symptoms

iPhone Mirroring app always shows “Try Again” / “Not Now”, never connects.

Continuity features like copy-paste, Continuity Camera, and Handoff don’t work either.

In Activity Monitor, I only see ContinuityAgent, but no continuityd process running.

In the iPhone Mirroring app’s Open Files and Ports, I see this key path:

/Users/helmybouchiha/Library/Containers/com.apple.ScreenContinuity/Data

This suggests it’s using the ScreenContinuity framework, but it looks like the main Continuity daemon isn’t running or registering properly.

What I’ve already tried

• Signed out and back in to my Apple ID on both devices (same account, 2FA enabled).
• Restarted both iPhone and Mac multiple times.
• Turned Bluetooth and Wi-Fi off/on on both devices.
• Reset Handoff, AirPlay, and Continuity toggles on iPhone.
• Manually deleted these files/folders on Mac:

~/Library/Containers/com.apple.ScreenContinuity
~/Library/Preferences/com.apple.continuity*
~/Library/Caches/com.apple.continuity*

• Killed and restarted related services:

killall sharingd
killall ControlCenter
killall cfprefsd

• Verified that continuityd is still not showing in Activity Monitor after reboot.

System details

• Mac: MacBook Pro M1 2020
• macOS: (26.0.1)
• iPhone: 16 pro max iOS 26.0.1
• Apple ID / 2FA: Same account, 2FA enabled
• Network: Both devices on same Wi-Fi

Questions

1. How can I verify if continuityd is missing, disabled, or corrupted on macOS?
2. Is there a way to reinstall or reset the ScreenContinuity / Continuity services without reinstalling the entire system?
3. Could this be a macOS Sequoia bug or an iCloud pairing issue?
4. Are there any logs I can check (Console or Terminal) to confirm why iPhone Mirroring fails to launch the session?

Extra notes

I suspect the problem is not just with the iPhone Mirroring app but with the Continuity framework itself, since no cross-device features work and the continuityd process is missing.

Thanks for any help or commands to re-enable or diagnose Continuity!
