Follow these steps to restart Handoff on a Mac. On iOS devices, go to Settings>General>Airplay & Settings and turn the toggle bar off and then back on for Handoff. Restarting Handoff can fix any temporary issues you may be experiencing. Devices being on different networks will cause Handoff to malfunction. If you use a common home network for all devices, make sure it is working as intended. Make sure your devices are on the same networkĪfter ensuring that Bluetooth and WiFi are enabled across all devices, you need to make sure that the devices engaging in Handoff are also connected to the same network. If everything is connected, turn the WiFi and Bluetooth off and then back on. Do the same for your Macbook and Apple Watch. Swipe up and check the control centre to see if WiFi and Bluetooth are enabled on your device. Handoff requires a stable WiFi and Bluetooth connection between devices to function seamlessly. You do have to trust both iCloud for your login and APN for messaging, but if that works for you, Handoff will work for you.Apple Watch (all models) Check if WiFi and Bluetooth are enabled The encrypted connection and transfer maintains your security. Otherwise, Handoff does everything it can to make sure you own the devices, have them in close proximity, and want to move your activities over. If you don't want to use it, you can easily disable Handoff on both iPhone and iPad and Mac. Handoff begins with the same BT LE connection, then engages Wi-Fi until the transfer is complete. Transferring larger amounts of data -for example, a filed attached to an email draft - uses peer-to-peer Wi-Fi, similar to AirDrop, along with standard transport layer security (TLS). (This is done via Apple's established mechanism for shared web credentials). In other words, the Facebook app has to prove it controls the website. Handoff also can transfer information between websites and apps, but before it does, the app has to prove it controls the domain of the website. For example, the URL of the web page you're reading, or iCloud document you're editing. Once triggered, Handoff will transfer small amounts of data using BT LE or APN along with the same encryption that handles the connection. Only then will Handoff actually "hand off". ![]() In every case, it takes an explicit action from you, the user. On the Mac, you can click on the Handoff icon in the Dock, or use CMD-Tab to select the Handoff icon within the application switcher. ![]() You do that by swiping up on your iOS device's Lock screen, or swiping left and tapping on the Handoff card within that device's multitasking app switcher. You, the person, still have to expressly pull that activity and data over. It doesn't push your activities and data between your devices at all times instead, it just lets you know an activity is available to resume, when and if you choose to. The real beauty of Handoff is that very little data gets transferred unless you elect to have it do so. Occasionally, if BT LE isn't optimal, APN can also handle the communication, again using the same encryption. Most of the time, communication happens over BT LE using the aforementioned encryption. If you're working on a presentation, Handoff will let those devices know you're using Keynote. So, for example, if you're browsing a web page, Handoff will let other devices know you're using Safari. It doesn't highlight any data or documents, however - just the app that you're using. ![]() Once the connection is made, Handoff will advertise new activities as they occur. Apple claims it also protects this communication against replay attacks as well. That means it uses a similar type of security to iMessage, generating a symmetric 256-bit AES key for each device and storing it within each device's keychain. When Handoff establishes a connection between your devices, it's established out-of-band using the Apple Push Notification (APN) service. ![]()
