  1. Capture the exact failure state

    Reversible

    Name the failing app, user account, port or peripheral and one that still works. Expected behavior: advertise eligible activity between nearby devices on the same account.

  2. Isolate the component boundary

    Reversible

    Confirm both devices use the same account with Bluetooth/Wi-Fi/Handoff enabled. Swap only the app, account, cable, port or user profile while keeping the computer unchanged. Boundary to separate: Apple Account and feature eligibility versus Bluetooth, Wi-Fi and app support.

  3. Correct only the proven cause

    Reversible

    Update, sign into the correct account or restart the one failed service. Repair the isolated app, user profile, driver binding or physical path.

  4. Verify and stop safely

    Reversible

    Retest both contexts after sign-in and one cold restart. Do not sign out of the account without synced data and credentials.
