Use Universal Clipboard on your Mac
Copy content from one device, and paste it into another nearby device within a short period of time. The contents of your clipboard are sent over Wi-Fi and made available to all Mac and iOS devices that are logged in with the same Apple ID and have Handoff, Wi-Fi, and Bluetooth turned on. See Use Handoff on your Mac.
Note: To use Universal Clipboard, you need an iPhone, iPad, or iPod touch with the Lightning connector and iOS 10 (or later) installed.
Use across apps. You can copy and paste images, text, photos, and video between any apps that support copy and paste on your Mac, iPhone, iPad, and iPod touch.
Copy and paste files. You can quickly move files from one Mac to another using Universal Clipboard. Copy a file on your MacBook Pro and paste it into a Finder window, Mail message, or any app that supports copy and paste on a nearby Mac. You must be signed in with the same Apple ID on both Macs.
