Use Universal Clipboard on your Mac
Copy content from one device, and paste it to 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, iPhone, iPad, and iPod touch devices that are signed 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 or USB-C connector and iOS 10 (or later) or iPadOS 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 Air and paste it to 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.
