There is a special kind of frustration in starting an email on your iPhone, sitting down at your Mac to finish it, and discovering that Handoff has quietly stopped working — usually right after a macOS or iOS update. The Handoff icon no longer appears in the Dock, Universal Clipboard refuses to paste between devices, and calls no longer hand off smoothly.
The reassuring news: an update rarely breaks Handoff for good. What usually happens is that the update resets a wireless setting, quietly toggles a Continuity feature off, or leaves your devices disagreeing about which Apple Account they are signed into. Work through the short checklist below and Handoff almost always comes back.
How to fix Handoff after an update
- Check the basics: proximity, Wi-Fi and Bluetooth. Keep both devices close together, switch Wi-Fi and Bluetooth on for each of them, and join both to the same Wi-Fi network. Then confirm both are signed in to the same Apple Account: on iPhone, open Settings and tap your name at the top; on Mac, open System Settings and check the name at the top of the sidebar. Many “broken Handoff” cases turn out to be two devices on different accounts after an update.
- Confirm Handoff is still enabled on both devices. Updates occasionally switch Continuity features off without telling you. On iPhone, go to Settings > General > AirPlay & Handoff and make sure Handoff is switched on. On Mac, open System Settings > General > AirDrop & Handoff and check that “Allow Handoff between this Mac and your iCloud devices” is enabled. Apple lists every requirement for Handoff and its sibling features in its Continuity system requirements guide.
- Restart both devices. A full restart clears the temporary glitches that updates leave behind. Power the iPhone and the Mac completely off, switch them back on, then test Handoff in a supported app such as Safari or Mail. When OS updates have disrupted Handoff for large numbers of users, 9to5Mac’s reporting has pointed to restarting every involved device and toggling Handoff off and on again as the first things to try.
- Sign out of iCloud on each device, then sign back in. If Handoff still refuses to cooperate, refresh the trust relationship between your devices. On iPhone, go to Settings > [your name] > Sign Out; on Mac, go to System Settings > [your name] > Sign Out. Then sign back in with the same Apple Account on both. This re-establishes the Continuity handshake and resolves the most stubborn cases. A quick way to verify success is Universal Clipboard: copy text on your iPhone and paste it on your Mac.
Handoff shares its foundations — Wi-Fi, Bluetooth and one Apple Account — with the rest of Apple’s Continuity family, so while you are at it you may enjoy our guides to setting up message sync between iPhone and Mac and automatic hotspot connection from iPhone on Mac.
If it still doesn’t work
Make sure both devices run recent software — Handoff needs a modern iOS and macOS on both ends. Temporarily disable any VPN, and check that the date and time are set automatically on both devices, since mismatched clocks can silently break Continuity. If one app refuses to hand off while others work, it probably lacks Handoff support.
Frequently asked questions
Why does Handoff break after an update?
Updates rewrite system settings, refresh network configurations and sometimes sign services out and back in. Any of those steps can leave the two devices with mismatched Handoff states — for example, Handoff toggled off on one device but on on the other. The checklist above re-aligns them.
Do I need Wi-Fi for Handoff, or is Bluetooth enough?
You need both. Bluetooth Low Energy handles device discovery, while Wi-Fi carries the actual data. Both devices must also share the same Wi-Fi network and the same Apple Account for the handshake to complete.
Conclusion
Handoff failing after an update is almost always a settings hiccup rather than real damage: check proximity and radios, confirm one shared Apple Account, verify Handoff is enabled on both devices, restart, and re-sign into iCloud if needed. Your Handoff will be passing web pages, emails and clipboard contents between iPhone and Mac again.
