How to Use Continuity
1 Start setting up Auto Unlock
Ensure your Mac’s Bluetooth and Wi-Fi are on, then that your Mac and Watch are signed in to iCloud with the same Apple ID (go to > System Prefs > iCloud on your Mac, and the Watch app > General > Apple ID on your phone).
2 More Auto Unlock settings
If you haven’t already, set up a passcode in the Watch app > Passcode on your iPhone. In > System Prefs > Security & Privacy on your Mac, enable ‘Allow your Apple Watch to unlock…’ and wait for the feature to activate.
3 Set up Handoff
To use Handoff, a Mac’s Wi-Fi must be turned on, even if it’s using Ethernet for networking. On your Mac, go to > System Prefs > General and turn on ‘Allow Handoff between this Mac and your iCloud devices’.
5 Set up Instant Hotspot
On your iPhone, go to Settings > Mobile Data and turn on the Personal Hotspot feature. From the Wi-Fi icon on your Mac, choose the name of your iPhone. On another iOS device, tap your iPhone’s name in Settings > Wi-Fi.
7 Choose devices for calls
Pick devices on which to make and receive calls. Turn on Calls From iPhone in FaceTime’s prefs on your Mac, and in Settings > FaceTime on other iOS devices. Incoming calls show as a notification on a Mac and a call screen on iOS.
4 Switch devices for a task
Enable it on iOS in Settings > General > Handoff. To move a task from iOS to Mac, click the Dock icon left of Finder’s. The other way, swipe up from the app icon on the Lock screen, or double-click Home and tap the banner.
6 Phone calls on all devices
Sign in to FaceTime on each device using the Apple ID you use for iCloud. Ensure your iPhone and other devices are on the same network. In Settings > Phone > Calls on Other Devices on the iPhone, enable ‘Allow Calls on…’.
8 SMS and MMS, everywhere
Your iMessage account in Messages’ prefs (Mac) and Apple ID in Settings > Messages > Send & Receive (iOS) must match. In iPhone’s Settings > Messages > Text Message Forwarding, enable devices; enter the code they receive.
