macOS Sierra: Copy and paste across devices
With Universal Clipboard, you can copy text, images, photos, and videos on one Apple device and then paste the content on another Apple device. For example, you can copy a recipe you found browsing the web on your Mac then paste it into a grocery list in Notes on your nearby iPhone.
Copy on a device: Select the content you want to copy, then copy it. For example, on your Mac, press Command-C or choose Edit > Copy.
The copied content is available to paste on your other devices only for a short time.
Paste on a device: Position the pointer where you want to paste the content, then paste it. For example, on your iPad, double tap, then choose Paste from the options.
Note: To use Universal Clipboard, your devices must meet Continuity system requirements. They must also have Wi-Fi, Bluetooth, and Handoff turned on in System Preferences (on your Mac) and in Settings (on your iOS devices). You must be signed in to iCloud using the same Apple ID on all your devices.
