A computer feature or peripheral that has completely stopped should be separated into driver, permission and physical-connection layers before assuming component failure. For Apple Handoff and Continuity, first confirm both devices use the same account with Bluetooth/Wi-Fi/Handoff enabled.
What this covers
- Apple Handoff and Continuity with this exact failure state
- Diagnosis across Apple Account and feature eligibility versus Bluetooth, Wi-Fi and app support
What it does not cover
Try in this order
0 of 4 completedCapture the exact failure state
ReversibleCheck Device Manager or System Information for whether the hardware is even detected, and whether an error code is shown. Expected behavior: advertise eligible activity between nearby devices on the same account.
Isolate the component boundary
ReversibleConfirm both devices use the same account with Bluetooth/Wi-Fi/Handoff enabled. Test the peripheral on a different port or user account, and test a different peripheral on the same port. Boundary to separate: Apple Account and feature eligibility versus Bluetooth, Wi-Fi and app support.
Correct only the proven cause
ReversibleUpdate, sign into the correct account or restart the one failed service. Reinstall or roll back the driver, or grant the missing app permission.
Verify and stop safely
ReversibleConfirm the feature works after a full restart in at least two different applications. Do not sign out of the account without synced data and credentials.
